When calculating the space used for pruning, if a log chunk is
compressed, that size is used otherwise the uncompressed size is
used. This is intended to reach a steady state where 1/4 of the log
buffer is the uncompressed log chunk that is being written to and the
other 3/4 of the log buffer is compressed logs.
If we wait until there are no readers referencing the log chunk before
compressing it, we end up with 2 uncompressed logs (the one that was
just filled, that readers are still referencing, and the new one that
was allocated to fit the most recent log), which take up 1/2 of the
log buffer's allotted size and will thus cause prune to delete more
compressed logs than it should.
Instead, we should always compress the log chunks in FinishWriting()
such that the compressed size will always be used for log chunks other
than the one that is not actively written to.
Decompressed logs due to readers are ephemeral by their nature and
thus don't add to the log buffer size for pruning.
Test: observe that log buffers can be filled in the presence of a reader.

std::bitset<> doesn't have exact replacements for all of the
functionality of BitSet32/64, so there are still places we want to use
these classes.

This reverts commit bd68757d44.
Reason for revert: reland test
The test now reboots after it is completed, in case there is some state it doesn't catch locally, and servicemanager restarts more of the system.

This patch adds support for handling return addresses signed with
pointer authentication. It simply strips the authentication code
without verifying its correctness, and thus works with both A and B
keys and through key-change boundaries.
Additons:
* DW_CFA_AARCH64_negate_ra_state: new CFA operation.
* RA_SIGN_STATE: new pseudo register.
* Pass the arch to DwarfCfa so that the new op is only executed
on aarch64.
The stripping uses the xpaclri instruction. This is a hint space
instruction which is compatible with pre Armv8.3-A devices. For cases
where it cannot be used, a mask can be set instead.
Test: libunwindstack_test
Without this patch all UnwindTest.* testcases should fail if
compiled with Pointer Authentication.
The tests should be executed with both -mbranch-protection=pac-ret and
pac-ret+leaf flags so that either some or all functions have pointer
authentication instructions.

This was a premature optimization. Profiling shows that decompressing
and deleting these logs is rather fast and overall CPU utilization is
lower without the added thread.

A previous change included sizeof(SerializedLogChunk) to the size of a
log chunk to more accurately track logd's log usage, but did not
update the tests that check this value, so this change updates them
appropriately.

Since tolower/toupper take and return integer arguments, ascii chars in
the extended range will be converted from positive int values to
negative char values. In order to silence an error here, which was added
recently with integer sanitization here, casting explicitly.

Most of the built-in functions return signed values but BitSet deals
only in unsigned values. We can safely cast these away though as they're
always indices, which can't be negative.

The mock RPMB can get out of sync with TD storage blocks in the event of
panic or crash. Making this O_SYNC will prevent this from happening.
