Summary:
eina: Implement Eina_Thread for native windows
The implementation design respects the fact that Eina_Thread is an
uintptr_t. Thus we allocate the thread struct in the heap and return a
pointer to it.
As such, we store the created thread structure in the target thread
TLS slot. For threads that were not created through eina API, in
eina_thread_self we allocate a new structure, push it to the TLS slot
and mark it to be freed on thread exit.

Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
EAPI is the only solution that worked for MSVC.

Eina Debug is a new layer aimed for EFL debugging. It offers scalability
by allowing registration of operations not specific to EFL core.
The protocol is simple and the APIs try to provide as much
functionalities/freedom as possible.
Summary: I had fixed some typos and some wrong expressions, such as capital letters, singular, and orders of groups in Eina API reference doxygen.

Built on top of the new 'postponed' free queue, the short-lived
strings API allows users to return new strings without caring
about freeing them. EFL main loop will do this automatically for
them you at a later point in time (at the end of an iteration).
The APIs provided will either duplicate (copy) or more generally
steal an existing string (char *, stringshare, tmpstr, strbuf),
taking ownership of it and controling its lifetime. Those strings
can then be safely returned by an API. From a user point of view,
those strings must be considered like simple const char *, ie.
no need to free() them and their validity is limited to the
local scope.
There is no function to remove such a string from the freeq.
The short lived strings API is not thread-safe: do not send a
short-lived object from one thread to another.

this adds eina_freeq api's for c land for deferring freeing of
pointers and can be used a s a simple copy & paste drop-in for free()
just to "do this later". the pointer will eveentually be freed as
eina_shutdown will free the main free queue and this will in turn free
everything in it. as long as the main lo0op keeps pumping things will
og on the queue and then be freed from it. free queues have limits so
if they get full they will clear out old pointers and free them so it
won't grow without bound. the default max is 1mb of data or 16384
items whichever limit is hit first and at that point the oldest item
will be freed to make room for the newest. the mainloop whenever it
finishes idle enterers will add an idler to spin and free while idle.
the sizes can be tuned and aruged about as to what defaults should be.
this also allows for better memory debugging too by being able to fill
freed memory with patterns if its small enough etc. etc.

As discussed in the mailing list, many people will use worker threads
to execute blocking syscalls and mandating ecore_thread_check() for
voluntary preemption reduces the ecore_thread usefulness a lot.
A clear example is ecore_con usage of connect() and getaddrinfo() in
threads. If the connect timeout expires, the thread will be cancelled,
but it was blocked on syscalls and they will hang around for long
time. If the application exits, ecore will print an error saying it
can SEGV.
Then enable access to pthread_setcancelstate(PTHREAD_CANCEL_ENABLE)
via eina_thread_cancellable_set(EINA_TRUE), to pthread_cancel() via
eina_thread_cancel(), to pthread_cleanup_push()/pthread_cleanup_pop()
via EINA_THREAD_CLEANUP_PUSH()/EINA_THREAD_CLEANUP_POP() and so on.
Ecore threads will enforce non-cancellable threads on its own code,
but the user may decide to enable that and allow cancellation, that's
not an issue since ecore_thread now plays well and use cleanup
functions.
Ecore con connect/resolve make use of that and enable cancellable
state, efl_net_dialer_tcp benefits a lot from that.
A good comparison of the benefit is to run:
./src/examples/ecore/efl_io_copier_example tcp://google.com:1234 :stdout:
before and after. It will timeout after 30s and with this patch the
thread is gone, no ecore error is printed about possible SEGV.
This is heavily inspired from Eo_Id infrastructure. Main change
are that the lower bit are always guaranteed to be zero and ignored
by all function. Also it may be a little bit less efficient in some
case, but we will tune it once we have real life usage of it.
Eo won't be migrated for 1.18 to it as Eo_Id is deeply integrated
and it is quite risky to touch it so close from a freeze. This can
wait.
Add a promise object that will allows Eolian interface to include promises
as a way to have asynchronous value return and composibility.
To understand better, let see the coming usage in a .eo file:
class Foo {
methods {
bar {
params {
@inout promise: Promise<int>;
}
}
}
}
Which will create the following API interface:
void foo_bar(Eo* obj, Eina_Promise** promise);
and the equivalent declaration for implementation.
However, the API function will instantiate the Promise for the user
and the implementer of the class automatically. So the user of this
function will treat it as a @out parameter, while the developer of the
function will treat it like a @inout parameter.
So, the user will use this function like this:
Eina_Promise* promise; // No need to instantiate
foo_bar(obj, &promise);
eina_promise_then(promise, callback);

This is a new feature for eina (and EFL) - a zero-copy thread message
queue for sending messages from one thread to another or from the
ecore mainloop to or back to the mainloop from threads. It has a
complete test suite too.
