Vadim Zeitlin 3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword.
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.

@defgroup group_funcmacro_debug Debugging macros
@ingroup group_funcmacro
Useful macros and functions for error checking and defensive programming.
Starting with wxWidgets 2.9.1, debugging support in wxWidgets is always
compiled in by default, you need to explicitly define ::wxDEBUG_LEVEL as 0 to
disable it completely. However, by default debugging macros are dormant in the
release builds, i.e. when the main program is compiled with the standard @c
NDEBUG symbol being defined. You may explicitly activate the debugging checks
in the release build by calling wxSetAssertHandler() with a custom function if
needed.
When debugging support is active, failure of both wxASSERT() and wxCHECK()
macros conditions result in a debug alert. When debugging support is inactive
or turned off entirely at compilation time, wxASSERT() and wxFAIL() macros
don't do anything while wxCHECK() still checks its condition and returns if it
fails, even if no alerts are shown to the user.
Finally, the compile time assertions don't happen during the run-time but
result in the compilation error messages if the condition they check fail.
They are always enabled and are not affected by ::wxDEBUG_LEVEL.
