When linker tries to check if a library without dt_soname is accessible
it crashes. This change fixes this problem to return false instead
(making them inaccessible from other namespaces)
This went unnoticed because vendor libraries on current
devices all have dt_soname set. This was only discovered
on one of the newer devices which has a vendor prebuilt
library without a soname.

The code (and comment) have been like this since the initial commit, but
there was never a test of this, and glibc seems to have been returning
EINVAL (as POSIX says it should) since long before Android existed.

Apparently this didn't make it to all android-16 devices. As far as
we know it did make it for all android-17 devices.

* Since Android does not have __tls_get_addr yet,
-fno-emulated-tls is only a test of compiler.
Lld is correct to reject this at link time.
But if the purpose of this test is to check at run-time,
allow_undefined-symbols is the trick to get the linked library.

When compiling on/for at least Lollipop, always use the fortified
versions of FD_X macros. This works around side-effect issues (which
are explicitly called out in the specification) and generally
increases robustness of code.

This reverts commit 2e7145c048.
When src is at the end page, the sse2 strlcpy SSE2 optimized version
can issue a movdqu instruction that can cross the page boundary. If
the next page is not allocated to that process, it leads to
segmentation fault. This is a rare but has be caught multiple times
during robustness testing.
We isolated a way to reproduce that issue outside of an Android device
and we have been able to resolve this particular case. However, we
ran some additional compliance and robustness tests and found several
other similar page crossing issues with this implementation.
In conclusion, this optimization needs to be re-written from scratch
because its design is at cause. In the meantime, it is better to
remove it.

Vendors that use config.fs will have their own uniquely named
user/group names for uids/gids that fall in the OEM ranges. We
continue to allow lookup via oem_## for these values, however the
returned structs will always include the name from config.fs, so we do
not check it for anything in the tests.

The default behavior for a real-time signal is to terminate the process.
If the child we fork sends a SIGRTMIN signal before we've set up the
ScopedSignalHandler for it, then the parent is terminated.

The tests can run in parallel, and if they do, one test can truncate
ld.config.txt while another test is reading it (via the loader). Fix the
issue by using a TemporaryFile as the LD_CONFIG_FILE.
