so there are 2 problems behind T7113. first is a problem in the efl
selection manager being "sloppy" with selection data. it's doing a
strlen on the data but it's not a normal c string. it's a blob of
binary data + length value. this fixes that "sloppiness" by using the
len field.
there is also another bug in the dnd test code that again has to do
with "sloppy" handling of data buffers and assuming nul byte
termination and not using the len field properly.
this fixes T7113.

1. multiple loops per single thread make no sense. so if multilpe loop

2. the app object is not really sharable in this design so it cant be
accessed from other threads
3. it makes it harder to get the main loop or app object (well 2 func
calls one calling the other and more typing. it is longer to type and
more work where it is not necessary, and again it can't work from

This commit adds the "documentation" generator, which gets the

to be exported by MCS.
For items requiring some customization of the generated comments (e.g.
functions and its parameters), the helpers to generate the preamble
(summary), body (paragraphs) and epilogue (currently just the @since
tag) were added.
Currently we do not support converting Eolian references into xmldoc

As we explicitly generate Get/Set methods for properties, for now the
generator tries to get the get/set specific documentation first. If it
is not present, fallback to the common docs.
Later this could be changed to generate the common one as paragraphs of
the Get/Set.
Also some generated code like the wrappers for calling C# methods
from C can be private. This will cleanup the introspection results
and warnings when generating documentation.
Due to this visibility change, the binbuf tests had to be changed
to add redirect calls to the native methods instead of directly

This resolves a few issues and brings back the experimental features.
Also, disable some of the ugliest experiments:
- manual function overrides,
- define APIs only in eo_cxx namespace
Some APIs are generated behind EFL_CXXPERIMENT (eg. event_name_cb_add or
some weak pointer stuff). I believe they are useful but would like to
make sure there are no serious drawbacks with generating those.
It's VERY hacky, but works as expected: no leak, no extra unref. This is
a lucky case of simply overriding efl_part() implementation in C++,
without having to modify the declaration.
This is part of the experimental stuff.
Allows calling C functions without using ._eo_ptr() explicitly. Probably
not super useful, assuming the interfaces are done :)
I'll hide some controversial features behind this, until we come to an
agreement with @felipealmeida and people who actually know C++ (iow: not
just me^^).
Features protected:
- easy wref (using -> without locking)
- xxx_event_cb_add() functions in object classes
- instantiate(obj) to create a new object
- add as a synonym for instantiate (both in efl::eo)
When I first implemented the Efl.Container interface I made a mistake of
mixing "single slot" content API's with "multiple children" content
API's. This should fix that, by separating API's that are for a single
part and those that deal with a list of children.
Efl.Content: Single slot. This will be used a lot by efl_part()
objects, and for the default content of widgets (eg. the window
content).
Efl.Container: Multiple children. Used by lists, boxes, layouts
(edje/elm), etc...
I didn't see any class that implemented both interfaces (note: Layout
implements Container and Button implements Content, so technically
Button implements both through inheritance).
For now the eo_prefix is not changed in Efl.Container. I wonder if it
should be reset (to efl_container) or not. This would only affect the C
API.
Ref T5328
Note: this is C only, not legacy only.
The problem is that bindings will hold a strong reference to the window,
which will then die "under the rug" if autodel is enabled. This then
leads to at least ERR if not crashes.
Note:
elm_policy needs to support autodel and quit on last del only for C
applications. Bindings will require some other mechanism that doesn't
break all assumptions wrt. references.
The fix is not complete. We need to make efl_part() work nicely in C++:
- Get the refs work properly (maybe without auto-del)
- Generate the parts from the EO file as methods on the object
Final form should be close to:
slider.indicator().format_string_set("%1.2f");
Where everything autocompletes nicely :)

make examples now builds all c++ examples but some of them are in fact
empty skeletons. Those either need some c++ love or the final eo api to
be ready (eg. menu, popup, ...).
I removed some examples that don't have an exact equivalent in EO since
the widget is legacy only.
This is more of an experiment than anything else.
@felipealmeida I would like to know what you think.
Notes:
- events still need a better API (event_add isn't part of the object
definition...).
- references are an issue, when you want to actually delete an object.
This isn't meant to be installed. The canvas API in EO is based around
the interfaces Efl.Canvas and the widget Efl.Ui.Win. Anything else is
not EO (eg: ecore_evas, evas, ...)
Note: evas_canvas3d is the last remaining thing that is installed along
EO files, but those are all beta APIs.
Summary:
Currently user ask for the root_node from the evas_vg object and then attach its tree by setting the root node as parent.
With this change this process will be explicit. user has to set the root node to the evas_vg object and the object will take the ownership
of the tree. User can query the current vg_tree by root_node_get api.

Fixed the test app to reflects this change.

Reasons:
- This API has been confused with the min size of the widget, resulting
in badly laid out applications.
- The EO API was not very nice (Range is about numbers, the Gfx size
hint in a part is really ugly).
While I understand the value of this API and how it can be used in
scalable applications, it is in fact not absolutely necessary.
Alternatively to that span size, the widget min size can already be
defined from the application side, or the widget can simply be expanded
to fill in its parent.
This can obviously be reinstated later if the need arises for EO. For
now, keep this feature as legacy-only.
I think this closes the orientation vs. direction problem.
RTL vs. AnyRTL is not fully handled yet but this becomes a
widget-per-widget issue (eg. should a box in a RTL locale be mirrored if
set to horizontal?).

For this patch I decided to add a pseudo legacy wrapper as the function
is called in a very large number of places. Fixing all those calls to
use the size2d form is a lot of work and a greater risk of b0rking
something.
It's a complex struct but defined in EO as a simple struct. ABI-wise
it's equivalent to Eina_Rectangle. Some macros that use Eina_Rectangle
also work on Eina_Rect out of the box, most of the code dealing with
x,y,w,h will require no modifications either.
But Eina_Rect provides direct access to a size or position 2d component,
as well as the usual x,y,w,h. The field "rect" is provided as a
convenience for code dealing with both Eina_Rectangle and Eina_Rect. We
may or may not require it.
Note: Size2D could use unsigned values but I have spotted a few places
in the code that actually use -1 to indicate invalid size (as opposed to
0x0).

- rotate_3d

- perspective_3d

@feature
In the map examples, the map image UV size was based on the image
source geometry, rather than the image geometry itself.
In the example, this affects how the glass is mirrored. Before this
patch, the reflection is a single line stretched. EFL 1.18 and 1.19
seem to have the same issue, while 1.17 simply fails to show any
reflection. 1.16 fails miserably and the entire window is black.
If the original code was correct, then I believe that map and/or
proxy rendering have been modified in a way that affects the meaning
of those image UV parameters. But this seems like the regression (if
it is one) is in fact quite old.

This is the local socket for windows, analogous to AF_UNIX.
`Efl_Net_Socket_Windows` is the base class doing `ReadFile()` and
`WriteFile()` using overlapped I/O, as well as the close procedure
(`FlushFileBuffers()`, `DisconnectNamedPipe()` and
`CloseHandle()`). These are done on top of an existing HANDLE that is
set by `Efl_Net_Dialer_Windows` (from `CreateFile()`) or
`Efl_Net_Server_Windows` (from `CreateNamedPipe()`).
The overlapped I/O will return immediately, either with operation
completed or `ERROR_IO_PENDING`, which means the kernel will execute
that asynchronously and will later `SetEvent(overlapped.hEvent)` which
is an event we wait on our main loop. That `overlapped` handle must
exist during the call lifetime, thus cannot be bound to `pd`, as we
may call `CancelIo()` but there is no guarantee the memory won't be
touched, in that case we keep the overlapped around, but without an
associated object.
Windows provides no notification "can read without blocking" or
non-blocking calls that returns partial data. The way to go is to use
these overlapped I/O, with an initial `ReadFile()` to an internal
buffer, once that operation finishes, we callback the user to says
there is something to read (`efl_io_reader_can_read_set()`) and wait
until `efl_io_reader_read()` is called to consume the available data,
then `ReadFile()` is called again to read more data to the same
internal buffer.
Likewise, there is no "can write without blocking" or non-blocking
calls that sends only partial data. The way to go is to get user bytes
in `efl_io_writer_write()` and copy them in an internal buffer, then
call `WriteFile()` on that and inform the user nothing else can be
written until that operation completes
(`efl_io_writer_can_write_set()`).
This is cumbersome since we say we "sent" stuff when we actually
didn't, it's still in our internal buffer (`pd->send.bytes`), but
nonetheless the kernel and the other peer may be adding even more
buffers, in this case we need to do a best effort to get it
delivery. A particular case is troublesome: `write() -> close()`, this
may result in `WriteFile()` pending, in this case we wait using
`GetOverlappedResult()`, *this is nasty and may block*, but it's the
only way I see to cope with such common use case.
Other operations, like ongoing `ReadFile()` or `ConnectNamedPipe()`
will be canceled using `CancelIo()`.
Q: Why no I/O Completion Port (IOCP) was used? Why no
CreateThreadpoolIo()? These perform much better!
A: These will call back from secondary threads, but in EFL we must
report back to the user in order to process incoming data or get
more data to send. That is, we serialize everything to the main
thread, making it impossible to use the benefits of IOCP and
similar such as CreateThreadpoolIo(). Since we'd need to wakeup the
main thread anyways, using `OVERLAPPED.hEvent` with
`ecore_main_win32_handler_add()` does the job as we expect.
Thanks to Vincent Torri (vtorri) for his help getting this code done
with an example on how to do the NamedPipe handling on Windows.
While in UNIX we use 'select()/poll()' to query for read fds and this
will eventually callback with "can_read" event, use the loop to match
other implementations where can_read keeps true if not all data was
read.

Summary:
The axis type joystick event could occur without user's control if joystick is too sensitive.
The deadzone prevents this unnecessary event. The default value is 200.
The event value for an axis is a signed integer between -32767 and +32767.
Test Plan: Using example

Efl.Model.Container and Efl.Model.Item to efl/interfaces are used
to create Efl.Model objects with predefined property values.
This is useful to any situation where we want an Efl.Model with
explicit defined property values.
Efl.Ui.View and Efl.Ui.Factory are used to connect Efl.Models with
Widgets, Elm.Layout and Efl.Ui.Image has changed to use news interfaces

Use seat names as prefix, not as suffix, following
a top-down approach and avoiding issues
with applications that may be receiving
doubled signals (legacy + suffixed).
So instead of "mouse,in,seat1" signal will be
"seat,seat1,mouse,in".
