0f8ab824a3 Fix using const char* and wxString in ternary operator
Using a const char* and a wxString in the two branches of the ternary
operator resulted in compile-time errors since the result type of the
conditional expression was ambiguous, so add explicit conversions to fix
it.

Closes https://github.com/wxWidgets/wxWidgets/pull/2634

See #19355.

ae1bcc5cb2 Show only the first difference when images differ in the tests
The code was supposed to do this, but didn't, as "break" only broke from
the inner loop, but not the outer one, so replace it with "return".

7eeff36635 Give more information in case of wxImage comparison failure
Show the value of the first differing pixel to get at least some idea of
what is wrong.

e70fc11ef1 Replace CppUnit with Catch for unit tests
Drop the legacy CppUnit testing framework used for the unit tests.
Replacing it with Catch has the advantage of not requiring CppUnit
libraries to be installed on the system in order to be able to run
tests (Catch is header-only and a copy of it is now included in the
main repository itself) and, in the future, of being able to write
the tests in a much more natural way.

For now, however, avoid changing the existing tests code as much as
[reasonably] possible to avoid introducing bugs in them and provide
the CppUnit compatibility macros in the new wx/catch_cppunit.h header
which allow to preserve the 99% of the existing code unchanged. Some
of the required changes are:

 - Decompose asserts using "a && b" conditions into multiple asserts
   checking "a" and "b" independently. This would have been better
   even with CppUnit (to know which part of condition exactly failed)
   and is required with Catch.

 - Use extra parentheses around such conditions when they can't be
   easily decomposed in the arrays test, due to the use of macros.
   This is not ideal from the point of view of messages given when
   the tests fail but will do for now.

 - Rewrite asserts using "a || b" as a combination of condition
   checks and assert macros. Again, this is better anyhow, and is
   required with Catch. Incidentally, this allowed to fix a bug in
   the "exec" unit test which didn't leave enough time for the new
   process to be launched before trying to kill it.

 - Remove multiple CPPUNIT_TEST_SUITE_NAMED_REGISTRATION() macros,
   our emulation of this macro can be used only once.

 - Provide string conversions using Catch-specific StringMaker for
   a couple of types.

 - Replace custom wxImage comparison with a Catch-specific matcher
   class.

 - Remove most of test running logic from test.cpp, in particular don't
   parse command line ourselves any longer but use Catch built-in
   command line parser. This is a source of a minor regression:
   previously, both "Foo" and "FooTestCase" could be used as the name of
   the test to run, but now only the latter is accepted.

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.

a25b5bbfc9 Make it easier to compare wxImages in the unit tests.
Instead of forcing the tests to manually use memcmp(), specialize
CppUnit::assertion_traits<> for wxImage. This allows to simply use
CPPUNIT_ASSERT_EQUAL() and related macros with wxImage objects.
