On OS X at least, the user is free to customize numbers formatting rules
and use more than one character for separators. Don’t assert in such
cases (the rules are untrusted input), but instead fall back to
something reasonable, as is already done if we can’t retrieve the rules.
We shouldn't add thousands separators nor remove trailing zeros for the
numbers in scientific format.
Also avoid "-0" as output.
See #15625.

Don't include the possible leading sign in the span of digits to be grouped as
this gave nonsensical strings such as "-,123" when adding thousands separators
to "123".

For some reason locale.h was only included in !wxUSE_STD_STRING case but we
actually always need it as we use LC_ALL in this file and at least in Sun CC
build it wasn't included from anywhere else so include it from here to fix the
build.

With at least MSVC9 numformatter.cpp wouldn't compile because of unknown identifiers related to locales. Include <locale.h> in case wxUSE_STD_STRING is set to 0.

Fixed commented names (path, filename, and extension) of files in include/ and src/. Prepended the names in src/ with "src/" everywhere, while starting those in include/wx/ with "wx/".

Also update the cached data if setlocale() was called explicitly instead of
using wxLocale to change the locale because at least under Unix systems
calling setlocale() changes the result of wxLocale::GetInfo() and so the
result returned by wxNumberFormatter::GetDecimalSeparator() and
GetThousandsSeparatorIfUsed() could be inconsistent with the locale being
really used.

Show more information in the assert failure message to try to understand why
is the unit test failing on the buildbot.

Caching the decimal and thousands separators in wxNumberFormatter is a useful
performance optimization, however it can give wrong results if the locale
changed since the cached values were initialized. So remember the locale used
for the initialization and redo it if it changed. This should still be almost
as fast as the previous version but now also correct (still not MT-safe
though).

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.

wxNumberFormatter formats and parses numbers with thousands separators.
Add the class itself as well as documentation and the unit test for it.
