a52a0daf84 Set TZDEFAULT to NULL. 
TZDEFAULT not applicable to bionic as there is no file per time
zone mapping.

5411aff6bb Bump tzcode from 2016g to 2022a*. 
Upstream has renamed tzsetlcl to tzset_unlocked. As bionic's
implementation of tzset_unlock differs from upstream, these changes were
skipped.

Also, upstream has removed constants (SECSPERMIN, etc) from tzfile.h. As
they are used in strptime.c, I've decided to leave them in tzfile.h and
to not bring them into strptime.c.

HAVE_TZNAME and USG_COMPAT flags semantics were updated, thus setting
their values to 2 in Android.bp file. See
1a27ec76bc

* 4742526b7e
and 0e8f0b06ac
were picked up, which are not part of 2022a.

Changes were applied using following commands:
  1) Checkout tzcode repo
  2) Prepare patches for all tzcode file using
    git diff 2016g 2021e -- <file-name> > <file-name-patch>
  3) Apply these patches to files in bionic using
    patch -p1 <file-name> <file-name-patch>

3031a7e45e memtag_stack: vfork and longjmp support. 
With memtag_stack, each function is responsible for cleaning up
allocation tags for its stack frame. Allocation tags for anything below
SP must match the address tag in SP.

Both vfork and longjmp implement non-local control transfer which
abandons part of the stack without proper cleanup. Update allocation
tags:
* For longjmp, we know both source and destination values of SP.
* For vfork, save the value of SP before exit() or exec*() - the only
  valid ways of ending the child process according to POSIX - and reset
  tags from there to SP-in-parent.

This is not 100% solid and can be confused by a number of hopefully
uncommon conditions:
* Segmented stacks.
* Longjmp from sigaltstack into the main stack.
* Some kind of userspace thread implementation using longjmp (that's UB,
  longjmp can only return to the caller on the current stack).
* and other strange things.

This change adds a sanity limit on the size of the tag cleanup. Also,
this logic is only activated in the binaries that carry the
NT_MEMTAG_STACK note (set by -fsanitize=memtag-stack) which is meant as
a debugging configuration, is not compatible with pre-armv9 CPUs, and
should not be set on production code.
