It's not really clear why, but clang 4.0 has decided to start giving warnings
about using the result of an expression constructed using the preprocessor
"defined" operation in #if checks, so trivially avoid doing this.
In addition to getting a major and minor OS version allow a micro
version to be retrieved. In case of running on e.g. OS X 10.10.3 this
allows the "3" to be retrieved again.
Use wxConvWhateverWorks when converting the command line given as a string to
individual arguments: we already used wxSafeConvertWX2MB() when converting the
arguments specified as an array, but not here.
Closes#16206.
Windows implements VerifyVersionInfo api since Win2k. Starting with Windows 8.1 GetVersionEx is deprecated and may not return the expected version number if the application does not contain the correct compatibility information in its manifest. VerifyVersionInfo works independent of manifest in the executable (and is the recommend way to check).
Existing code may already use wxPlatformInfo::CheckOSVersion() so the method forwards the call to wxCheckOsVersion if initialized for the current system.
The code for doing this was accidentally disabled in r74957, which intended to
disable it for Darwin, but ended up disabling it for everything but Darwin.
Reenable it for all platforms now, clearly it didn't hurt to have it enabled
under Darwin, and we do need to do it, e.g. see #12636.

wxExecute() closes all file descriptors in the forked child process.
This is a common practice, but it unfortunately breaks in combination
with libdispatch on OS X, which - instead of gracefully handling the
situation - intentionally(!) crashes when something closes its kevent
file descriptor in OS X 10.8.
There's doesn't seem to be a simple way to get this descriptor and
there's no telling when libdispatch is pulled into the executable, so
just leave the file descriptors be when running under Darwin, until a
better fix is found.

The code mistakenly assigned the lowest possible priority (0, in wx's
numbering), while the intention probably was to have the same default as
wxProcess, which is 0 in POSIX numbering and 50== wxPRIORITY_DEFAULT in
wx's.
Fixes permission denied errors if lowering priority is not permitted.

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.

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.

Get rid of the surprising src/common/execcmn.cpp which had a .cpp extension

The code closing all file descriptors inherited from the parent in the child
process created by wxExecute() was removed in r57324 by mistake (probably
due the fact that its meaning was poorly explained) but we still do need to do
this, of course, to avoid descriptor "leaks" (e.g. the parent couldn't really
close any of them).
Restore the code for closing all unneeded file descriptors in the child in
slightly modified form and add a comment pointing to an URL explaining how to
do it better in the future.

Since the child pipe was made non-blocking in r65993, it became possible to
write to child process without deadlocking when the pipe became full. However
this still resulted in an error from wxFileOutputStream as it didn't handle
EAGAIN returned from write() any differently than any other error, even though
it is an expected situation in this particular case.
Change Unix wxExecute() to use wxPipeOutputStream which ignores EAGAIN unlike
wxFileOutputStream to fix this.
See #12636.

We need to make at least one end of the pipe used to communicate with
wxExecute() child process non-blocking to avoid deadlocks, so unblock the
write end of the pipe. It seems to be unnecessary to unblock the reading ends
of std{out,err} pipes as we can already check for the presence of input there.
This is also consistent with wxMSW behaviour.

The caller expects the function to return -1 if the child process exited with
-1 error code and not 255 that was returned before. The function is also
documented as returning -1 if the execution fails which wasn't true neither.
Fix this by explicitly handling the exit code as signed.
