Add a new property to disable io_uring and run vts and snapuserd_test
snapuserd: Async I/O for block verification
snapuserd: Use io_uring api's for snapshot merge
Hard to get otherwise if you're trying to debug PAC issues.

musl libc defines NULL as nullptr, which is explicitly allowed by
C++11. nullptr_t cannot be implicitly cast to an integral type.
Use 0 instead.

This change provide a specialization of android::base::OkOrFail for
status_t. As a result, a statement whose type is status_t can be used
with OR_RETURN.
The specialization also provides conversion operators to Result<T,
StatusT> where StatusT is a wrapper type for status_t. This allows
OR_RETURN macro to be used in newer functions that returns Result<T,
StatusT>.
Example usage:
\#include <utils/ErrorsMacros.h>
status_t legacy_inner();
status_t legacy_outer() {
OR_RETURN(legacy_inner());
return OK;
}
Result<T, StatusT> new_outer() {
OR_RETURN(legacy_inner()); // the same macro
return T{...};
}

* changes:
Mount /mnt/scracth with -o sync,nodiscard
Run check_fs only /data is mounted
Don't use FSCK_LOG_FILE used for ext4 only
Don't try to mount if the disk has no FS magic
Retry to unmount /data
"-o discard" issues UNMAP commands to loopback resulting in punch_hole
on the pinned file in /data. That will break the pinned block map.

Adding `--host` for host-side test cases with atest, so we
still can run the test when there is no device connected.
Otherwise, TradeFed will emit the follow error:
