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

The boot failure symptom is reproduced on Walleye devices. System boots
up after taking OTA and try to upgrade key, but keymaster returns "failed
to ugprade key". Device reboots to recovery mode because of the failure,
and finally trapped in bootloader screen. Possible scenario is:
(After taking OTA)
vold sends old key and op=UPGRADE to keymaster
keymaster creates and saves new key to RPMB, responses new key to vold
vold saves new key as temp key
vold renames temp key to main key -------------- (1) -- still in cache
vold sends old key and op=DELETE_KEY to keymaster
keymaster removes old key from RPMB ------------ (2) -- write directly to RPMB
==> SYSTEM INTERRUPTED BY CRASH OR SOMETHING; ALL CACHE LOST.
==> System boots up, key in RPMB is deleted but key in storage is old key.
Solution: A Fsync is required between (1) and (2) to cover this case.

Test: Insert fault right after deleteKey in vold::begin (KeyStorage.cpp),
original boot failure symptom is NOT reproducible.
