Add a mutex in MapInfo, and a mutex in Elf. Lock the creation of an Elf
file using the MapInfo mutex, and lock when calling Step, GetFunctionName,
or GetSoname since they can modify information in the object. It might
be beneficial to use a fine grained lock in the future.
Change the Maps object to contain a vector of MapInfo pointers rather
than the total objects. This avoids copying this data around.
Add a test to libbacktrace to verify that sharing a map while doing
unwinds in different threads works.
Add concurrency tests in libunwindstack to verify the locking works.
Add always inline to the RegsGetLocal arm and aarch64 functions. I had
a case where clang did not inline the code, so make sure this is specified.

Test: New unit tests to cover the case. Passes all unit tests.

Test: Remove the locking and verified that all of the concurrenty tests fail.

(cherry picked from commit 26335f89b1)
In https://github.com/torvalds/linux/commit/8db6c34f1dbc8 , namespaced
file capabilities were introduced. That change updated VFS_CAP_REVISION
from VFS_CAP_REVISION_2 to VFS_CAP_REVISION_3.
Android code is written assuming v2 capabilities, and the code will
break if we naively try to treat a v2 structure as a v3 structure.
So don't even try.
Android kernels prior to v4.14 will not support this extended capability
structure, so attempting to set such capabilities will ultimately fail.
With 8db6c34f1dbc8, it appears that attempting to read a v3 capabilities
xattr will always downgrade the capability to a v2 capability, so it
really doesn't make sense to look for a v3 capability.
Android capabilities are only created at /system and /vendor filesystem
creation time by host tools. Android processes, within or outside a
namespace, are not permitted CAP_SETFCAP
(https://android-review.googlesource.com/c/platform/system/sepolicy/+/547801/1/public/domain.te
line 1101). So we should never have to deal with a v3 capability other
than those that might appear on the /system / /vendor partition at a
future date by a future author.

If the platform has no bootloader or pstore support, kernel_panic
test should fail if the results are not correct. Drop skipping of
failed test if pstore support is lacking.
If device demonstrably has pstore content support, the result must
be exacting kernel_panic,sysrq. Otherwise accept the less precise
result.
Test: On hikey960 (which currently lacks reliable pstore, or a
compliant bootloader reporting bootreason), expect failure of:
system/core/bootstat/boot_reason_test.sh kernel_panic

This change explicitly drops all inheritable capabilities (and, by
extension, ambient capabilities) when there are no explicit capabilities
being set by a service and the user is changed. This prevents Android
running in a container from accidentally granting extra capabilities to
services.

This is paving the way to allow an "override" tag

AID_SHARED_GID is a GID shared by a specific app across all users on
the same device. Bring the UserHandle and multiuser.c implementations
into agreement, and copy/paste the unit tests that verify that both
behave identically.
This fixes a regression where multiuser_get_shared_gid() was applying
per-user isolation when it shouldn't have.
