Replace user-specified empty constructors and destructors with the
compiler-generated versions, which has a number of advantages for code
generation, in addition to being more clear.
Closes#22965.
Closes#24058.
Having this line is not useful at all as it doesn't contain any
information and shouldn't be filled in the future as git-shortlog can
provide the information about people who changed the given file more
more reliably than consulting the comments in any case.
Keep the non-blank lines for historical purposes.
Always use std::unordered_{map,set} when we use them at all, don't
bother with checking for their availability and with tr1 or even older
alternatives.
This workaround was already disabled for MSVC, as it resulted in a
warning there, but it also gives a similar warning with clang and it
seems better to restrict this workaround to gcc only rather than
excluding another compiler.
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 reverts r70556, i.e. removes the scope operators added by it to all
WX_DECLARE_HASH_{MAP,SET} macros, and implements a workaround for the problem
due to the use of empty base class optimization in g++ 4.7 standard library
implementations inside the macros themselves by prepending the hasher and
comparator classes with explicit "struct".

Macros from WX_DECLARE_HASH_SET family could declare an operator->() which
could never be called because it returned a pointer to a non-object (e.g. a
pointer or a primitive type).
Fix this in the same way as for WX_DECLARE_ARRAY macros by adding (badly but
consistently) named _PTR variants of the macros to allow defining the versions
without operator->().
This fixes tons of warnings when building wx with Sun CC.

Previously, wxUSE_STL enabled both implicit conversion of wxString to
std::[w]string and use of standard containers for the implementation of their
wx equivalents. Split up the two roles now by allowing to enable the use of
the standard containers independently of (backwards incompatible) implicit
conversion in wxString and actually enable wxUSE_STD_CONTAINERS by default.
