Since this function is used in userspace reboot, we need to be more
diligent with error handling, e.g.:
* If init fails to read /sys/block/zram0/backing_dev, then fail and
fallback to hard reboot.
* Always call swapoff.
* Always reset zram.
* Tear down loop device only if zram is backed by a loop device.
Test: adb reboot userspace

(cherry picked from commit a840d405eb)
Previously, we weren't distinguishing between nonexistent devices and
devices that don't support features, resulting in lots of stuff being
broken for pre-N devices.

This function is responsible for majority of CPU time in prefetto.
Reduce the number of memory reads (don't read strings byte-by-byte).
Update all calls of ReadString to include the third parameter to have
a max read.
Add an Elf creation benchmark since this function is on the elf
creation path.

libsnapshot* uses update_metadata-protos. This
used to be optimized out, but now that SnapshotManager is
virtual, CreateUpdateSnapshots can no longer be optimized out.

This is preferred over SnapshotMergeStats::GetInstance because
the latter needs a concrete SnapshotManager, not the ISnapshotManager
interface.
SnapshotManagerStub::GetSnapshotMergeStatsInstance returns
a SnapshotMergeStatsStub instance.

Avoid crashes in update_engine. When SnapshotManager
should not be used (e.g. Virtual A/B is not enabled),
use the stub instead.

ELF symbols are not sorted by address. Create remap table
which reshuffles the indices into sorted-by-address order.
This saves over 6x of memory (the remap table needs just
uint32_t per entry, as opposed the FuncInfo cache entry).
ART symbols are sorted. Make use of that fact.

The month field is one based in the zipfile modification time. And
it causes an overflow converting it to struct tm. Switch to type to
signed integer to suppress the sub-overflow.

We can't use the sysdeps.h copy of this code, so for now add yet
another copy & paste. We should come up with something better in
libbase, but let's get the macOS build fixed first.

tl,dr;
Increase the attempts to 50 to reduce the chances of failing
to load the serial console. This will only happen if the cmdline
parameter "androidboot.first_stage_console=1" is enabled.
Details:
10 attempts only amounts to about 1 second of trying to open the serial
console. I tested booting an ACK GKI image 5x with 20 vendor modules and
found the serial console loaded on attempt 17 for all five boot
tests.

This test is pretty straight forward: create two large files, then merge
one into the other while injecting kernel crashes. At the end,
block-by-block validation is performed against both the snapshot-merge target
and the file written to disk.

The newer way of specifying the interface is using <fqname> and it also
has the handy side-effect of not causing conflicts when we add the
strongbox implementation to devices.

Some of the test cases in CtsInitTestCases and CtsFsMgrTestCases require
root. This CL makes it possible to run such tests cases on userdebug
builds, which in turn means that they will be run on presubmit.

There's no need to pull in <fcntl.h> to get O_NONBLOCK, since the
ANDROID_LOG_* macros are better standalone.
Also note that 0x00000003 should be reserved since these corresponded
to previously used values.
