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.

userlandfs: libbsd.so is referenced as "libbsd.so".

Fixes the build.

Use explicit_bzero where it makes sense

userlandfs: Fix build breakage on GCC2.

userlandfs: Fix the BeOS frontend on 64-bit.

Use libstdc++, libsupc++ and libgcc from gcc_syslibs.

* Instead of faking libstdc++.so from libstdc++.a, use libstdc++.so
from the gcc_syslibs build feature for everything except x86_gcc2.
* Use libgcc_s.so from the gcc_syslibs build feature for everything but
x86_gcc2 (which still carries libgcc as part of libroot.so).
* Drop filtering of libgcc objects for libroot, as that is no longer
necessary since we're only using libgcc-as-single-object for libroot
with x86_gcc2, where the filtered object file doesn't exist. Should
the objects that used to be filtered cause any problems as part of
libgcc_s.so, we can always filter them as part of the gcc build.
* Use libsupc++.so from the gcc_syslibs build feature for everything but
x86_gcc2.
* Adjust all Jamfiles accordingly.
* Deactivate building of faked libstdc++.so for non-x86-gcc2. For
x86_gcc2, we still build libstdc++.so from the sources in the Haiku
source tree as part of the Haiku build .
* Put gcc_syslibs package onto the image, when needed.

* merged 32bit-wchar_t branches of buildtools and haiku back into
the respective trunk

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31443 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed UserlandFSServer to userlandfs_server. It is expected to live in
/system/servers, now.
* Got rid of the dispatcher application. It was the entity the kernel module
talked to when mounting a yet unknown FS. It started the client FS server
applications. Now the kernel module starts them directly. They use
respectively named ports, so the kernel module can find them when already
running.
