Otherwise only the pids are shown, and it's hard to tell which
processes actually got killed.

- Remove bind mounting Android/ code as we want to bind mount obb dir
for each process instead.
- Set property "vold.vold.fuse_running_users" as an array of user id
for which fuse is ready to use.
- After fuse is ready for a user, fork a background process in vold
to bind mount all direct boot apps for that user so its direct boot
apps obb dir will be mounted to lower fs for imporoved performance.

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.

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.

Start with clang-analyzer-security* and cert-*, but disable two
specific errors:
-- cert-err34-c, which checks for atoi(); heavily triggered by
CommandListener, but will disappear when we move to Binder.
-- cert-err58-cpp, which checks for exceptions before main(); it's
a "Low" severity issue, and filed 36656327 to track cleanup.
Fix all other triggered errors along the way.

for loop devices.

When unmounting an emulated volume, look for apps with open files
using the final published volume path.
Without this change, we were only looking at the internal paths
used for runtime permissions, which apps never use directly. This
meant we'd always fail to unmount the volume if apps didn't respect
the EJECTING broadcast, and volume migration would end up wedged
until the device rebooted.

Sadly setexeccon() is process global, so we need to carefully ensure
that all exec() are mutually exclusive to avoid transitioning into
unwanted domains. Also, because we have several threads floating
around, we need to guard all our FDs with O_CLOEXEC.
Format all newly created volumes immediately after partitioning,
but silence all events emitted from those volumes to prevent the
framework from getting all excited. Unify all notify events under a
single codepath to make them easy to silence.
Sent SIGINT before escalating to SIGTERM when unmounting.

Wire up new Disk and VolumeBase objects and events to start replacing
older DirectVolume code. Use filesystem UUID as visible PublicVolume
name to be more deterministic.
When starting, create DiskSource instances based on fstab, and watch
for kernel devices to appear. Turn matching devices into Disk
objects, scan for partitions, and create any relevant VolumeBase
objects. Broadcast all of these events towards userspace so the
framework can decide what to mount.
Keep track of the primary VolumeBase, and update the new per-user
/storage/self/primary symlink for all started users.
Provide a reset command that framework uses to start from a known
state when runtime is restarted. When vold is unexpectedly killed,
try recovering by unmounting everything under /mnt and /storage
before moving forward.
Remove UMS sharing support for now, since no current devices support
it; MTP is the recommended solution going forward because it offers
better multi-user support.
Switch killProcessesWithOpenFiles() to directly take signal. Fix
one SOCK_CLOEXEC bug, but SELinux says there are more lurking.

-Wno-missing-field-initializers is used as well, but that is an
overzealous warning from initializing structs with {0} and not a
real warning.

Just in case someone tries to set up a series of links to trick us, do a
quick sanity check on the total length of the strings we're about to
concatenate.
