This brings stdatomic.h into -STABLE and includes improvements to tgmath.h that
significantly decrease compile times on a C11 compiler (such as the clang in
the base system).

Merge quick_exit and changes required for C++11 code to compile against FreeBSD headers.

This currently defines __NO_TLS on ARM (unlike head), because the required
support function has not been MFC'd.

MFC r234785:

2012-05-17T10:25:34+00:00

Add a convenience macro for the returns_twice attribute, and apply it to
the prototypes of the appropriate functions (getcontext, savectx,
setjmp, sigsetjmp and vfork).

MFC r228924:

2012-02-28T23:30:19+00:00

In POSIX.1-2008:

P_tmpdir [OB XSI]  Default directory prefix for tempnam().

This macro is used in a lot of places in legacy applications,
and is why we see a lot of programs written for e.g. Linux
store volatile temporary files in /var/tmp and not /tmp.

MFC r231118:

2012-02-14T19:36:35+00:00

Consistently set RPCGEN_CPP when running rpcgen, so the C preprocessor
set via ${CPP} is used, instead of always using hardcoded /usr/bin/cpp.

MFC r229590 manually:

  It turns out our GCC has quite an interesting bug:

        typeof(1.0fi) != float _Complex
        typeof((float _Complex)1.0fi) != float _Complex
        typeof((float _Complex)1.0i) == float _Complex

  In other words: if casting to an equal size, GCC seems to take a
  shortcut. By casting down from a double to a float, GCC doesn't take
  this shortcut, yielding the proper type.

MFC r229768:

2012-01-21T01:24:06+00:00

Implement fdlopen(3), an rtld interface to load shared object by file
descriptor.
