userlandfs: use std::bitset for FSCapabilities

gcc 13 is confused by the custom bitset implementation, so use the C++
standard one instead.

However, this results in including the C++ <string> header in kernel
code. This doesn't work for gcc2, because of two problems:

- That header includes a declaration of atomic_add that doesn't match
the one in SupportsDefs.h (which can in some cases replace the function
with a #define for an inline version). Adjust the header to use the
be a problem because it creates a risk of circular inclusions.
Standard C++ headers shouldn't depend on BeAPI ones.
- It also leads to the inclusion of iostream which defined lock and
unlock functions in the global namespace. We don't want these, and they
are not part of the C++ standard, so just remove them.

Ideally we could use std::hash for the GetHashCode implementation, but
that doesn't work because it depends on an helper function that's in
libstdc++, and we can't link that from kernel add-ons.

build fix.

* can't use min here, this header is not supposed to #include
<algorithm>.

Add another missing string::compare method

* Makes our gcc2 slightly more C++98 compliant...

Add another mssing string::compare prototype.

Matches buildtools change 8b70c20ed25f905e7e217376c9e2f65a8dee6729.

Remove remaining unnecessary 'volatile' qualifiers

Allow use of c_str() on wstring.

Fix #7948: add correct prototype for String::compare alongside the wrong one
for BeOS compatibility.

* Added missing clear() method.

* Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

- added implementation of stdc++ for haiku
- this differs slightly from the one that lives in buildtools/gcc as it
has been "ported" to the newer libio that haiku uses as part of its own
