Update static functions/macro definitions.
Fix the list of static functions coming from swab.h to match the
ones exported by glibc.
Force the definition of __HAVE_BUILTIN_BSWAP{16,32,64}__ so the headers
use the builtin.
Add a unit test to guarantee that kernel header updates do not break this.

loader: enable loading libraries from tmpfs
This change adds two tests for dlopen from temporary files.
1. One Uses memfd_create() can be used to load libraries directly
from memory. This requires relaxing namespace accessibility check
in order to make this work in isolated namespaces.
2. Another checks that open with O_TMPFILE works.

libc: fix typo in __RENAME macro
Apparently __strncpy_real redirects to strcpy instead of strncpy for GCC
builds. This is bad, and it confused a project compiled by GCC that uses
strcpy.
I audited all of the FORTIFY-related __RENAMEs both manually and with a
script I hacked together; they all look correct aside from this one.
FWIW, with the cleaned up clang FORTIFY, lots of the `void foo()
__RENAME(foo)` will just become `void foo()` if this last thing I'm

Avoid "D linker : (null)" with debug.ld.all for dlerror.
We only want to know when dlerror is actually set. The previous change
to this logic moved it so that we only show actual updates to dlerror,
not every string that might end up in dlerror's output. This change
ignores cases where we're _clearing_ dlerror (which happens on every
call to dlerror).

Report the right error code from PropertyServiceConnection()
We're currently reporting errno from the clean up call to close(),
which is much less interesting than the failing connect() call that
precedes it. This change reports errno from the connect() call
instead.
