Due to a bug in MSVC handling of __VA_ARGS__ (see
https://connect.microsoft.com/VisualStudio/feedback/details/380090/variadic-macro-replacement)
wxCALL_FOR_EACH() didn't work correctly as long as more than two arguments
were used with it.
Work around the bug by protecting __VA_ARGS__ from being incorrectly passed as
a single token to the macro being called on every step: this was already done
for wxCALL_FOR_EACH itself with wxCALL_FOR_EACH_, but we need to do it for all
the helper macros too.
Also add a test checking that this does, actually, work.

The use of variadic macros results in a warning/error if -pedantic[-errors]
is used when compiling C++98 code as they are only formally part of C99 (or
C++11). With g++ 4 and later, this can be avoided by using -Wno-variadic-macros
option, but it doesn't exist in g++ 3, so a nasty workaround in the header
itself is required: mark it as system header in order to fix compilation.

Don't test for wxUSE_NORLANDER_HEADERS, this is always true since many, many
years.
Remove tests for gcc version < 3.3, notably 2.95: the minimal supported gcc
version is 3.4.
Closes#15727.

This compiler is not being developed since several years and almost certainly
can't be used to build the current wxWidgets sources anyhow, so remove all
support for it, including a lot of extremely ugly workarounds for its bugs
with template functions.

Don't support this compiler any more, this allows to get rid of tons of
MSVC6-specific workarounds, in particular we can now use Bind() and natural
template functions calls in the library code.
Also remove MSVC6 project and solution files and don't generate them when
bakefile_gen is ran any more (removing the remaining occurrences of msvc6prj
from the bakefiles results in weird bake-time errors, so it's simpler to just
leave them there).

This avoids g++ warning about HAVE_VARIADIC_MACROS redefinition in setup.h if
wx/cpp.h happens to be included before it.

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 solves the problem with wx/defs.h -> wx/platform.h -> wx/setup.h which
resolves to msvc/wx/setup.h -> wx/version.h -> wx/cpp.h include path which
resulted in __VISUALC__ not being defined in wx/cpp.h.
This problem was not new but went unnoticed for a long time and was only
discovered when wxCHECK_VISUALC_VERSION() started being used in wx/cpp.h too
as now the compiler started warning about wrong #if syntax due to it being
undefined.
Putting the compiler-specific definitions in a separate file allows this file
to be included from wx/cpp.h to ensure that these symbols are always defined
in it and also makes things a little better organized.

The main user-visible effect of this change is that giving configure
--disable-vararg-macros argument now really disables the use of variadic
macros whereas it didn't disable them in wx/cpp.h before.
It is, of course, also less confusing to not have two very similar but
different symbols.

This loop can't be optimized away by the compiler because wxFalse is an extern
variable which can't be known to be always false. Additionally, this creates
many false positives from Coverity as it assumes that the loop can be executed
more than once.
Define wxSTATEMENT_MACRO_BEGIN/END macros abstracting the exact solution used
and replace wxFalse with "(void)0, 0" for now as this seems to placate MSVC
(which warns about using a bare "0" as a condition) while still allowing the
loop to be completely optimized away.
