The changes of r69564 making "environ" declaration unconditional broke
MinGW 4.6 build, presumably because "environ" is declared differently (as DLL
exported?) there, so avoid declaring it under MSW, we don't need to do it
there anyhow as it's always defined in system headers.

It doesn't make sense to require passing C functions to wxQsort() that we
define in a C++ library. We also don't need any special calling convention
here.
Notice that the only existing uses of wxQsort() inside wxWidgets itself were
not actually extern "C" and one of them didn't even use the correct calling
convention.
Also avoid using non-wx-prefixed CMPFUNCDATA identifier in a public header,
rename it to wxSortCallback instead.
Finally make wxQsort() documentation slightly more useful.

While POSIX and SUS both mandate this variable existence, they don't say that
it needs to be declared anywhere and it actually doesn't seem to be declared
under Solaris when using Sun CC and so using it resulted in compilation errors.
Just declare it ourselves to avoid them.

Implement support for wxHELP for wxMSW, wxGTK and wxOSX/Cocoa (at least when
showing the message box from the main thread, there doesn't seem to be any way
to show more than three buttons with CFUserNotificationDisplayAlert() so
"Help" button is not supported when using it).
This is useful not only on its own, i.e. to allow the user to ask for help,
but also because it brings the total number of buttons supported by the
message dialog to 4, meaning that more choices can be offered to the user
(which is rarely, but not quite never, useful).

Additionally renamed wxOSX' private wxNativePrinterDC::Ok() function to IsOk().
Didn't deprecate the various Ok() functions: given the amount of changes already introduced in 3.0 a trivial one like this seems more suitable for after 3.0.

Add simple wxVersionInfo class holding the version information.
Also add GetLibraryVersionInfo() static method to wx{JPEG,PNG,TIFF}Handler,
wxStyledTextCtrl and wxXmlDocument classes and wxGetZlibVersionInfo() and
wxGetLibraryVersionInfo() global functions using it.
Closes#12690.

Add an optional wxExecuteEnv parameter to wxExecute() which allows to specify
the initial working directory and custom environment for the child process.

Use wxDELETE[A]() functions which automatically NULL out their arguments after
deleting them instead of doing it manually.

This function is not needed in wxGTK2 as GTK+ sets detectable auto-repeat on
its own in gdk_display_open() anyhow, so move its implementation to
src/x11/utilsx.cpp where it can be used by wxX11 and wxMotif which do need it.

This function was mistakenly defined in a section of utilscmn.cpp compiled as
part of wxBase, so it wasn't correctly exported from the core library and
linking any wxX11 applications failed when using compiler with visibility
support.

Also disable sizer-drawing code unless wxDEBUG_LEVEL>=2 as we don't want it to
be available in production versions.
