Merge "Fix dlopen of main executable by absolute path" into nyc-dev

linker: Allow caller to specify parent namespace
This change enables apps to share libraries opened
with RTLD_GLOBAL between different classloader namespaces.
The new parameter to create_namespace allows native_loader
to instruct the linker to share libraries belonging to
global group from a specified namespace instead of
using the caller_ns.

Fix linker crash on trying to unload main executable
Linker crashed if linking of the main executable fails
instead of aborting with readable error message.
This patch modifies unload to soinfo_unload it all at once
in this particular case. This helps avoid situations when
one of the libraries on the DT_NEEDED list of main executable
has gotten unloaded by previous library unload because it
DT_NEEDED it too.
Example (consider following dependency tree):
main_executable
|-> liba.so
|-> libb.so
|-> libb.so
The list of the libraries need to be unloaded in this case
is [liba.so, libb.so], but if linker does unload one by one
by the time it gets to libb.so - the soinfo for the library
is already unloaded (and the segments were unmapped).
Passing everything as an array helps soinfo_unload to check
if a library was already unloaded by looking into local_unload_list.

Add unwind information for r7 in arm syscalls.
It turns out that clang can emit code where the sp is saved in the r7
register on arm. Unfortunately, a lot of our syscalls overwrite that

fails.

Add a test exercising ptrace watchpoint functionality
This adds a test which verifies that watchpoints work on devices
which support them. It is motivated by issues experienced by Nexus
5 devices, where watchpoints work only sporadically.
These tests spawn a process, trace it, and verify it hits a
watchpoint of various sizes while executing on all available CPUs
(to help catch a recent bug, where some debugging functionality
was not available on non-boot CPUs). All x86(_64) targets are
expected to support this functionality. In case of arm(64),
watchpoints are expected to work on devices where the relevant
syscall indicates watchpoint presence. In case of mips, this test
is skipped as I could not verify that the test would work
correctly due to lack of hardware, and this test is intrinsically
hardware-dependend.

Revert "Update timezone data to 2016b"
The bionic change merged down from upstream but the
external/icu one didn't.
A replacement change will be submitted along with one for
external/icu.
This reverts commit

Update timezone data to 2016b
Changes affecting future time stamps
New zones Europe/Astrakhan and Europe/Ulyanovsk for Astrakhan and
Ulyanovsk Oblasts, Russia, both of which will switch from +03 to +04 on
2016-03-27 at 02:00 local time. They need distinct zones since their
post-1970 histories disagree. New zone Asia/Barnaul for Altai Krai and
Altai Republic, Russia, which will switch from +06 to +07 on the same date
and local time. Also, Asia/Sakhalin moves from +10 to +11 on 2016-03-27
at 02:00. (Thanks to Alexander Krivenyshev for the heads-up, and to
Matt Johnson and Stepan Golosunov for followup.)
As a trial of a new system that needs less information to be made up,
the new zones use numeric time zone abbreviations like "+04"
instead of invented abbreviations like "ASTT".
Haiti will not observe DST in 2016. (Thanks to Jean Antoine via
Steffen Thorsen.)
Palestine's spring-forward transition on 2016-03-26 is at 01:00, not 00:00.
(Thanks to Hannah Kreitem.) Guess future transitions will be March's last
Saturday at 01:00, not March's last Friday at 24:00.
Changes affecting past time stamps
Europe/Chisinau observed DST during 1990, and switched from +04 to
+03 at 1990-05-06 02:00, instead of switching from +03 to +02.
(Thanks to Stepan Golosunov.)
1991 abbreviations in Europe/Samara should be SAMT/SAMST, not
KUYT/KUYST. (Thanks to Stepan Golosunov.)
The update produced (apparently benign) warnings from zic as suggested here:

Fix race in malloc debug option free_track.
The free track mechanism could fail if, at the same time a free occurs,
another thread is trying to free and verify the same allocation. This
doesn't work if the freed allocation is added to the list and we still
do work on it. The fix is to only add to the free list when we are done
with the allocation.
Also fix a problem where the usable size is computed incorrectly because
two of the arguments where reversed.
In addition, add a check that the allocation being verified has the correct
tag before trying to check the body of the allocation.
Add a test to catch the original failure.
Add a test for the tag being different.

Fix problem where unknown option is not an error.
If the first option is found, then any unknown options are simply
ignored, but do not produce an error. Fixed this so that each
option found is actually verified to exist.
