Moving this to LIBC_DEPRECATED caused compatibility
problems for some apps.

(cherry picked from commit 2167e74f16)
In order to implement android::base::WaitForProperty well, we need a way to
wait not for *any* property to change (__system_property_wait_any), but to
specifically wait for the property represented by a given `prop_info` to
change.
The android::base::WaitForProperty implementation, like attempts to cache
system properties in the past, also needs a way to keep serials and values
in sync, but the existing functions don't provide a cheap way to get a
consistent snapshot. Change the __system_property_read_callback callback's
type to include the serial corresponding to the given value.
Add a test, slightly clean up some of the existing tests (and name them to
include the names of the functions they're testing, in our usual style).

This change introduces new __system_property_read_callback
method to use in place of deprecated __system_property_read
__system_property_set() and get() should just work but now
do not have limit on system property names.

These functions are supposed to be used only by the
property service.
__system_property_find_nth is deprecated and no longer part
of NDK. Call to this function will result in abort for apps
targeting Android O.

POSIX locale only, as usual.
The GNU YESSTR and NOSTR extensions return the empty string in the C locale,
so I haven't bothered supporting them.

Also fix <sys/ipc.h>.
Not useful except to systems/bringup folks for testing. Trivial tests
added, and double-checked under strace to see that things look right.

Hiding our legacy cruft seemed like a good idea, but in practice it will only
mean worse interoperability.
Plus we got it wrong, as the recent `putw` example showed.

With this change (and all the others below it in the stack), the only
difference between the arm android-9 libc.so in r13-beta1 and the one
we are now generating is the addition of LIBC_N and LIBC_O versions.
Test: make ndk, readelf stub libc.so to check symbol exists

These functions were erroneously released in LIBC_PRIVATE for M, but
in fact need to be public. Since we need to be able to load them on M
even if they were built for a lower platform (and M needs to load on
newer platforms), we need to unversion them.

Spotted these while cleaning up <sys/cdefs.h> --- if we remove __USE_XOPEN2K8,
libchrome decides you "must" have futimes. Adding the missing functions (all
just alternative interfaces to utimensat(2) system call) lets us clean up
without breaking anything.

* Fix the return type of towlower_l/towupper_l.
* Implement wctrans/wctrans_l/towctrans/towctrans_l.
* Move declarations that POSIX says are available from both <wchar.h> and
<wctype.h> to <bits/wctype.h> and include from both POSIX headers.
* Write the missing tests.

Not efficient to iterate through given the large number of Android
ids (AID). Compile warning will result if you use these functions,
telling you as much. Not for general consumption, however for
example, some filesystem tests would like to see these to perform
all corners.
About 1/4 second for getpwent, and 1/8 second for getgrent to iterate
through all reserved Android aids.

android_net_res_stats_get_info_for_net returns the current name servers, search
domains, parameters and stats for the given network ID.
android_net_res_stats_aggregate provides statistics such as errors counts from
the raw stats data reported by android_net_res_stats_get_info_for_net.
android_net_res_stats_get_usable_servers uses the data returned by
android_net_res_stats_aggregate to determine which of the servers are
considered valid or broken by the resolver.

It turns out that at least the Nexus 9 kernel is built without CONFIG_QUOTA.
If we decide we're going to mandate quota functionality, I'm happy for us to
be a part of CTS that ensures that happens, but I don't want to be first, so
there's not much to test here other than "will it compile?". The strace
output looks right though.

Implement the legacy SysV signal handling functions sighold(),
sigignore(), sigpause(), sigrelse(), and sigset() in terms of the newer
POSIX signal APIs. As of POSIX 2013 the SysV signal APIs are deprecated
but still required.

{get,set}domainname aren't in POSIX but are widely-implemented
extensions.
The Linux kernel provides a setdomainname syscall but not a symmetric
getdomainname syscall, since it expects userspace to get the domain name
from uname(2).

Also guard both these GNU extensions with _GNU_SOURCE.
Also improve the tests to test each case on both the current thread and
another thread, since the code paths are totally different.
