F2FS changes proper configurations along with gc_urgent, so idle-maint doesn't
need to set this redundantly.

Use vold version of writeStringToFile which fsync files, and
manually fsync directories after initialize global DE

Test: Build pass and reboot stress test.
Original boot failure symptom is NOT reproducible.

The expression "!fd" calls the implicit conversion to int, but comparing
the raw fd against 0 does not work, since open() and other POSIX calls
returning a file descriptor use -1 to signal an error.
Test: m vold

This changes the property from microsecond to milliseconds, as we don't
need that sort of precision here. Also switches from using ulseep, which
has been removed from POSIX, to nanosleep.
Test: Builds, Boots, Times

std::ifstream does not use O_CLOEXEC flag when opening files. This leads
to file descriptors being inherited by child processes. In the case of vold
this results in leaking FDs to less privileged children with no permission
for these files which occasionally leads to SELinux denials.

Take action if we are running out of checkpoint space.
Configurable via ro.sys properties.
ro.sys.cp_usleeptime = Time to sleep between checks
ro.sys.cp_min_free_bytes = Min free space to act on
ro.sys.cp_commit_on_full = action to take. Either commits or reboots to
continue attempt without checkpoint, or retry
and eventually abort OTA
Test: Trigger a checkpoint and fill the disk.

abortChanges will attempt to pass a reboot message, and will only reboot
if the device is currently checkpointing. Additionally, it can opt to
attempt to prevent future attempts. This only works for non-bootloader
controlled updates. Failures are ignored, as it will always reboot the
device. In the unlikely event of such a failure, the device will
continue to retry as though you did not ask to prevent future attempts.
Test: vdc checkpoint abortChanges abort_retry_test 1
vdc checkpoint abortChanges abort_noretry_test 0

This makes needCheckpoint return true when the device will or is using
checkpointing.
Test: vdc checkpoint startCheckpoint 1
reboot
vdc checkpoint needsCheckpoint
should return 1 before and after data mounts, and 0 once the
checkpoint has been committed

Also add vdc checkpoint supportsFileCheckpoint
This is to allow tests to be specific to supported checkpoint mode.
Test: Built on Taimen and Crosshatch, made sure both new functions work
as expected
