Prefix all HIDL HAL types with the letter H.
Also make the invocation more generic so that we can use
the AIDL implementation in the future.

When the idle maintenance task runs on Cuttlefish, there are several
warnings printed to logcat after the expected messages:
D vold : Starting trim of /data
I vold : Trimmed 0 bytes on /data in 36ms
D vold : Starting trim of /cache
I vold : Trimmed 58662912 bytes on /cache in 0ms
D vold : Starting trim of /metadata
I vold : Trimmed 7725056 bytes on /metadata in 12ms
D vold : Starting trim of none
W vold : Failed to open none: No such file or directory
D vold : Starting trim of /sdcard
W vold : Failed to open /sdcard: Not a directory
D vold : Starting trim of /mnt/vendor/shared
W vold : Trim failed on /mnt/vendor/shared: Inappropriate ioctl for device
This is because vold gathers the filesystems to trim from the fstab, but
it fails to exclude some entries that aren't appropriate to trim:
/dev/block/zram0 none swap defaults zramsize=75%
/tmp /sdcard none defaults,bind recoveryonly
shared /mnt/vendor/shared virtiofs nosuid,nodev,noatime nofail
These should be excluded because they are swap space, a bind mount, and
a virtual filesystem respectively.
Fix addFromFstab() to exclude the above cases.
Afterwards, the messages on Cuttlefish are:
D vold : Starting trim of /data
I vold : Trimmed 0 bytes on /data in 39ms
D vold : Starting trim of /cache
I vold : Trimmed 58662912 bytes on /cache in 0ms
D vold : Starting trim of /metadata
I vold : Trimmed 9822208 bytes on /metadata in 12ms

vold already reads the default fstab into memory when starting up, and
the default fstab isn't allowed to change later. So in IdleMaint.cpp,
just use 'fstab_default' instead of reading it again.
This also has the advantage that fstab entries for "logical partitions"
now get a properly updated blk_device, which is needed in order to start
using blk_device to exclude virtual filesystems in addFromFstab().

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

This activates device GCs in idle time.
F2FS GC = 7 mins
Trim = 1 mins
Dev GC = 2 mins

runIdleMaint is equivalent with:
1. echo 1 > /sys/fs/f2fs/sdX/gc_urgent
2. wait until /sys/fs/f2fs/sdX/dirty_segments
<= threshold or timeout
3. echo 0 > /sys/fs/f2fs/sdX/gc_urgent
4. fstrim
abortIdleMaint forces the wait loop above to exit and
skips fstrim. However, if fstrim is already running,
abortIdleMaint will just leave it run to completion.

We've been allocating task objects without freeing them, oops. We
don't really need full classes for these tasks, so move them to
blocking methods, and invoke them from a detached thread.
Remove FIDTRIM support, which isn't meaningful on UFS-based flash
devices. Modern devices require FBE/FDE which gives us better
protection against trimmed data lingering around.
Rename "Trim" to more generic "IdleMaint", since it'll soon extend
to include custom F2FS optimization logic.
Check for shady ".." when validating paths.
