Added to each ucontext_t for source compatibility between platforms where
sigset_t and sigset64_t differ (arm, x86) and where they're the same
(all the rest).

Use the malloc debug framework to implement the malloc debug hooks
since it can introduce a performance issue.
Also, modify the bionic/tests/utils.h slightly to dump an error message
when the exe failed.
Bug: 30561479
Test: Ran malloc hook unit tests.
Test: Ran malloc debug unit tests.
Test: Enabled malloc hooks and ran bionic unit tests and verified no
Test: unexpected failures.
Test: Enabled malloc debug and malloc hooks and verified malloc debug wins.
Test: Enabled malloc debug using env, property, and property with name
Test: still works.

(cherry picked from commit d6a1dc2379)
Every other architecture already uses an assembly file here.
The previous code aligned ESP incorrectly, but it doesn't really matter
because everything is built with Clang's -mstackrealign, which realigns
ESP in every function prologue.

Caused problems for some Google source switching to unified headers
because the legacy headers just used #define instead.

We now have a proper mechanism for OEMs to create new AIDs via
config.fs and /vendor/etc/{passwd,group}. This means that there is no
reason for OEMs to add AIDs by modifying android_filesystem_config.h,
and therefore we can add this check back.
Bug: 27999086
Test: pwd and grp tests pass with custom AIDs in config.fs
This reverts commit a14485adde.

sigset_t is already large enough on mips so use the same principle
as on LP64 architectures: typedef sigset_t sigset64_t
Also prevent accessing sa_restorer field for architectures which
don't define SA_RESTORER in signal_test.
This allows compilation of signal_test.

The (lowest) address of the argument area (aka ESP immediately prior to
the call instruction) must be aligned to 0 mod 16. Here, it is aligned to
12 mod 16.
From the SysV ABI doc (2.2.2 The Stack Frame)
"""The end of the input argument area shall be aligned on a 16 (32, if
__m256 is passed on stack) byte boundary. In other words, the value
(%esp + 4) is always a multiple of 16 (32) when control is transferred to
the function entry point."""
Test: extract code into a separate C file and verify stack alignment in a
"start_main" function
Test: use the upcoming NDK r17-beta1 (with new Bionic crtbegin*.o files)
with an M-23 x86 system image, check alignment in main (compiled with
Clang not GCC, compiled w/o -mstackrealign)

The math on the size calculation was wrong as the type of
__exidx_start/__exidx_end was unsigned rather than a char. Make a
struct that represents each item instead and remove the division.

These three functions are the only reason we need libandroid_support
post-L. Add these so we can remove it entirely for LP64 or users
targeting L+.
Test: make checkbuild
Test: build/soong/scripts/build-ndk-prebuilts.sh
Test: Imported the prebuilts generated from the above to the NDK,
`./checkbuild.py && ./run_tests.py` with a handful of patches
to remove libandroid_support for L+.

Now that we have a clang that supports transparent overloads, we can
kill all of this cruft, and restore our upstream sources to their
untouched glory. Woohoo!

The error handling was a mess, resulting in an infinite loop
(and a test timeout) if you actually took the /dev/urandom
fallback. I'm also unconvinced that the getrandom(2) path was correct
because of the various reasons why we might get a short count back
(http://man7.org/linux/man-pages/man2/getrandom.2.html). In this version,
the two paths look very similar except for the getrandom(2) failure case,
where it's now much clearer that we just give up so that we can boot
(http://b/33059407).

This change does not enable EDNS0, so it should not
result in any behavior change. However, enabling EDNS0
should now be possible with only a small additional change
to "flip the switch".
This change has also landed in NetBSD upstream
(http://gnats.netbsd.org/52578) so this change reduces
divergence from upstream.
Most of the code in this change is for caching of queries that contain
an additional section.

Test: Added integration tests for fallback to the netd suite.
