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.

622bc15f11 Add conversions to/from long long to wxUniChar.
Allow conversions to/from long long and unsigned long long values in wxUniChar
for consistency with the other integral types.

Also make the code shorter by using helper wxDO_FOR_INT_TYPES() and
wxDO_FOR_CHAR_INT_TYPES() macros to avoid duplicating the same code for all of
the integral types and having to handle wchar_t (and wxLongLong_t now)
specially because sometimes we may need to overload on it and sometimes not.

Finally, add more tests to check that all the wxUniChar methods compile and
work with all the different types.

Closes #15206.

8421cb3c7c Fix bugs in parsing wxLongLong values starting with zeroes.
wxCRT_StrtoullBase(), used by wxString::To[U]LongLong(), didn't handle leading
zeroes nor leading 0x correctly: it never auto-detected base 8; didn't ignore
the leading 0 even if base 8 was specified explicitly; didn't recognize "0X"
prefix at all (only "0x").

Fix all these bugs and add test cases for parsing numbers in other bases to
the unit tests.

Closes #14596.

Comparisons didn't work correctly in the other direction as they were not

wxUniChar and wxUniCharRef.

556a836e0f Don't cache incorrect length in wxString::assign(char*, size_t).
The length of the string here is specified in bytes and is not the same as the
string length for non-ASCII UTF-8 strings, so don't cache it as the string
length.

Just invalidate the cached length instead as we simply don't know what the
real length of the string is going to be.

See #14130.

bd42a07c7a Fix caching wrong length in wxString(str, len) ctor in UTF-8 build.
A length greater than that of the source string could be passed to this ctor.
This worked correctly, i.e. created a string which was a copy of the source
one but cached a wrong length for it.

Avoid this by explicitly checking the length before caching it in
wxString::assign(str, len).

f2c6e60762 Ensure wxCharTypeBuffer data is NUL-terminated after extend() call.
As wxCharTypeBuffer ctor taking the length NUL-terminates the buffer, it may
be expected that extend() does the same but it did not. Do add the NUL at the
end for consistency, even though it's not really needed for the existing code
using extend() in wxWidgets itself.

cda937864f Fix VarArgTestCase compilation when type traits are unavailable.
When type traits are unavailable we can't check whether a type can be passed

it will fail with the assert at run-time.

d326d52cd9 Use setUp/tearDown() for NumFormatter test case locale setup.
Setting the locale in the ctor of the test object doesn't work because the
locale is changed by the other tests that run before this one, use the
initialization method provided by cppunit to change the locale instead, this
is somewhat wasteful but at least it does work, unlike the old version.

f2a5052baa Add support for long long to wxNumberFormatter.
It seems to make sense to allow using it for formatting and parsing long long
values as well as it can be done trivially using almost the same code as for
long.

It would be nice to support long double in a similar way but we don't wrap
C99 strtold() right now so it wouldn't be as simple, leave it for later.

Move USING_VC_CRT into testprec.h to allow its reuse in other files and rename

the CRT we use.

5858fe6806 Don't use native MSW functions in wxString::CmpNoCase().
While the native CompareString() is much more efficient than MSVC CRT version
of _wcsicmp(), it gives unexpected results for non-letter characters, so don't
use it but use the slow but correct wxStricmp() instead.

At least don't use char-by-char comparison (in non-UTF-8 case) as it's the
slowest possible implementation of this function, the new one using
wxStricmp() is 3 times faster (by comparison, using CompareString() is 16
times faster still -- but wrong).

3acf8a8d9b Remove wxLOCALE_CONV_ENCODING flag.
This doesn't affect Unicode builds, only the legacy ANSI one.

PO files are now always converted to the appropriate charset according
to current locale. This was the default behavior for long time; not
doing the conversion was always a fragile hack that didn't work well.
Removing this flag simplifies wxLocale code.

e3ab69523b Add wxString::ToStdString() and ToStdWstring().
These trivial helper functions are available in all builds (provided that
wxUSE_STD_STRING is not explicitly set to non-default 0 value) unlike implicit
conversions to std::[w]string which are only available when wxUSE_STL==1.

cbab155657 No real changes, just fix a typo in comments and documentation.
Use "surprising" instead of (common) "surprizing" misspelling.

874dbd3a4a Allow calling wxStrchr() with a narrow string and wide character.
Calls to wxStrchr(char-string, wide-char) would previously fail if wide
character couldn't be converted to a single character in the current locale
encoding. Change it to simply return NULL in this case as it's a safe and
useful generalization: a narrow string will never contain a wide character not
representable in the current locale.

Add wxUniChar::GetAsChar() to help with implementing this.

Closes #11487.

bbb0ff36db Fix another off-by-1 bug in wxMBConv::ToWChar().
When converting a fixed number of characters we need to take any NULs inside
the buffer being converted into account for our return value -- but this
wasn't done and converting 2 characters 'x' and '\0' returned only 1, even if
the length 2 was explicitly specified.

Fix this bug and add a unit test checking for it.
