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.
Test: adb shell sm idle-maint [run|abort]

We heavily leverage sgdisk, which already has a bunch of logic to
optimally align partitions. We've been using it for the adoptable
storage GPT tables, and now we also use it for MBR tables.

Moves away from crufty char* operations to std::string utility
methods, including android::base methods for splitting/parsing.
Rewrite of how Process handles scanning procfs for filesystem
references; now uses fts(3) for more sane traversal.
Replace sscanf() with new FindValue() method, also has unit tests.
Remove some unused methods. Switch almost everyone over to using
modern logging library.

Now that we've moved to Binder, we only have a few lingering atoi()
usages that are cleaned up in this CL.
Rewrite match_multi_entry() entirely, with tests to verify both old
and new implementations.

If the invoked FUSE binary fails to mount the requested filesystem,
the dev_t won't actually change. To avoid getting waiting forever
and triggering the watchdog, timeout after 5 seconds.
Test: manually hang after fork and verify that we timeout

Create IVoldListener and move most unsolicited vold events over to
this new interface. The remaining events will be routed through
method-specific listeners instead of a global one.
Move to upstream DISALLOW_COPY_AND_ASSIGN macro.

This moves fstrim, obb and appfuse commands over to the new Binder
interface. This change also separates creating/destroying and
mounting/unmounting of OBB volumes, which means they finally flow
nicely into the modern VolumeInfo/VolumeBase design.
We now generate unique identifiers for all OBB volumes, instead of
using a shady MD5 hash.
Change all "loop" and "dm" devices to tag the kernel resources with
a vold-specific prefix so that we can clean them up if vold crashes;
there are new destroyAll() methods that handle this cleanup.
Move appfuse mounting/unmounting into VolumeManager so it can be
shared. Move various model objects into a separate directory to
tidy things up.
