Make overriding virtual methods more explicit and enable additional checks
provided by C++11 compilers when "override" is used.

Don't repeat the same code in all the ports, move it to the common base class
and add a new virtual DoYieldFor() for the really port-specific code.

This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

This commit changes wxExecute() to handle SIGCHLD to be notified about the
child process termination instead of detecting when the file descriptor
corresponding to the other end of a pipe opened in the parent process was
closed in the child as this was not reliable and could (and did) result in not
detecting the termination of the child processes that closed all their file
descriptors before exiting.
This commit also removes a lot of platform-specific code duplicating the
generic event loop sources support and reuses it for wxExecute() purposes too.
Final big change is that wxEndProcessData was merged into wxExecuteData and we
don't have two similar but quite different classes any more but just one,
which is used both to pass the information from wxExecute() to wxAppTraits
methods and to store this information until the child termination.
Closes#10258.

No real changes but use wxEventLoopSource::AddSourceForFD() instead of
wxFDIODispatcher::RegisterFD() for this pipe because this is the preferred way
and because it will allow reusing this class for wxExecute() purposes later.
See #10258.

Any event sources should be registered with all the event loops, including the
ones that will be started in the future, and not only the current (and
potentially not even existing yet) one. So make AddSourceForFD() method static.
To still allow it to do different things in console and GUI applications, as
it must, virtualize it via the new wxEventLoopSourcesManager class which has
different implementations in the two cases, returned via wxAppTraits as usual.
Notice that this required moving the implementation of this method from
src/osx/core/evtloop_cf.cpp to src/osx/core/utilsexc_cf.cpp as the former file
is base-only and didn't have access to wxGUIAppTraits.

This class can also be useful when it's used in the main thread only, so
leave the lock-less part of the code in wxWakeUpPipe and derive a separate
wxWakeUpPipeMT from it for the use in wxConsoleEventLoop where it can be used
by multiple threads.
See #10258.

Initialize m_pipeIsEmpty to true as we don't have anything in the pipe
initially and if this variable was false, nothing was ever written to the wake
up pipe and it was never set to true as nothing was read from it neither.

Generating many wake ups from the worker threads could result in overflowing
the buffer of the pipe used to communicate with the main thread which, in
turn, resulted in other serious problems (deadlocks...).
Avoid this by only writing to the pipe if it is empty.

Simply extract part of the code from evtloopunix.cpp into a reusable
wxPipe::MakeNonBlocking() function to be able to reuse it elsewhere.
See #12636.

Currently wxEventLoopSource can't be created directly and can only be used to
monitor file descriptors so reduce the API to just wxEventLoop::AddSourceForFD()
and remove AddSource(), RemoveSource() and RemoveAllSources() which couldn't
be implemented for all ports. This makes the code much simpler without any
loss of functionality.
Make wxEventLoopSource responsible for removing itself from the event loop
when it is deleted. This allows to remove IsOk() and Invalidate() methods
making the code simpler and gets rid of various sets/maps which were used
before.
This also allows to support event loop sources in Carbon as well: wxOSX/Carbon
now compiles and works with wxUSE_FSWATCHER==1.

Merges everything from the branch with only some minor changes, mostly renamed
wxUSE_FSWATCHER_{INOTIFY,KQUEUE} to wxHAS_{INOTIFY,KQUEUE}.
Add wxFileSystemWatcher and related classes.
Also introduces wxEventLoopSource.

We must unregister the wake up pipe file descriptor which we register with the
IO dispatcher in wxConsoleEventLoop ctor, otherwise doing it the next time
(i.e. if wxConsoleEventLoop is deleted and recreated) results in asserts, at
least when using wxSelectDispatcher and not wxEpollDispatcher (i.e. under any
non-Linux Unix system).

so Unix' wxConsoleEventLoop can also be shared by platforms not having
the complete ConsoleAppTraits of Unix (e.g. OS/2).
