if proxy fails are too many then give up on queued lookups as they
likely will continue. i noticed a process continually spawning efl net
proxy helper because one queued lookup failed and could be looked up
so it kept trying again and again.

This is a new type representing a mutable string (no const).
Regular strings cannot be made mutable with @owned because
they might be hidden behind typedefs.
Summary: I had fixed some typos and wrong expressions, such as capital letters, $simbols in .eo and singulars in Ecore, Ecore_Audio, Ecore_Cocoa, Ecore_Con, and Ector API reference doxygen.

It's unlikely that we'll have other stuff under Ip namespace, also not
that likely to have other than Ip Addresses (to invert it to
Address.Ip), thus make a toplevel entry Ip_Address as suggested by
DaveMDS.
Gcc complains that 'flags' here may be used uninitialized. In looking
at the code, 'flags' does not seem to be needed in the debug prints
here. If we keep and initialize the variable to 0 during declaration,
it would only ever print out 0 anyway as 'flags' is never changed in the
code.

Summary:
The _ecore_con_post_event_server_upgrade() call adds an event to free
the server_upgrade object, svr, via _ecore_con_server_free(svr) so we
should assume srv is freed after it returns. Thus, perform the
pending_slice processing prior to calling it. Otherwise it triggers an
illegal access (USE_AFTER_FREE) error in Coverity.

for dialers we should also monitor "resolved" from inner TCP socket
and emit that ourselves, letting people know that we have an IP
address.
this is important for ecore_con_legacy.c, since the svr->ip is only
decoded and stored once when this signal is emitted.
Since efl_net_ssl_context is immutable for a dialer and we create the
dialer with the context, the SSL cases uses a trick to postpone dialer
creation using a job, then it allows one main loop iteration for the
user to call various ecore_con_server_ssl_*() methods.
However this breaks immediate ecore_con_server_send() after
ecore_con_server_connect() as used to be allowed and used by
azy/erssd.
Most people wouldn't notice that, since the most common case is to
either use ecore_con_url (which uses cURL and a complete different
code path) OR they would wait for ECORE_CON_EVENT_SERVER_ADD prior to
sending data.
Nonetheless it was a compatibility issue and must be fixed.

currently it's being defined in evil_fcntl.h, but the actual
implementation of fcntl() in evil_fcntl.c is causing problems with
sockets. So one possibility is to remove the ifdef, another is to
change the implementation.
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.

so ecore_con/efl_net were using the standard ecore_thread thread pool
for doing things like dns lookups (that can take multiple minutes
until timeouts) and actual http transactions. similarly they can block
thread workers for long periods or indefinitely thus basically
blocking the whole eocre_thread pool and stopping others from sharing
it. the best solution we have right now is to bypass the thread pool
queue and have dedicated threads for these actions. what we should
have is a dedicated thread pool with each thread taking on N
connections (via select etc.) and the ability to create and destroy
thread pools for specific tasks so you can separate the work out from
other work. but that is basically a redesign of our thread pool infra
so let's do the quick solution here until that day comes.
this partially addresses D4640
a dedicated thread per image load though is going to be a lot nastier...
After we call curl_multi_socket_action() we must call
_efl_net_dialer_http_curlm_check() in order to call
curl_multi_info_read() and be notified of handles that were
finished. Otherwise the handle is gone and we'll be waiting for an
action that will never happen.

Now you can't use the same syntax as you would for a method to
implement a property as whole, instead you need to specify the
getter and/or setter explicitly. This is to allow parent classes
to expand their properties without altering behavior of the child
classes.
