4b6ca4ea65 Update vold to log only debug or higher level messages.
This will allow adding lots of verbose logs which can be enabled
only during local testing/debugging. Update the existing verbose
level logs to debug level since we want those to be logged by
default.

Test: manual

3472e52fc2 Move to modern utility methods from android::base.
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.

67b8c49530 Make Loop::destroyAll() smarter.
Instead of blindly looping across 4096 possible devices, use
readdir() to only look at valid devices.  This speeds up destroyAll()
from 40ms to 0.7ms.

Add tracing information in several places.

11c2d380a7 Move even more vold commands over to Binder.
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.

32ebb739cb Enable clang-tidy for security sensitive domain.
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.

a4f48d0f44 vold: fix 64 bit ioctl error
Changing the num_sectors used in ioctl with BLKGETSIZE because
the kernel expects an unsigned long type and then changes 64 bits
with a 64 bits userspace. This overwrites what's located close to
the parameter location if any.

ce6a913aea Exclusive exec() path, format after partition.
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.

8439dc9fd5 Make vold compile with -Werror -Wall.
-Wno-missing-field-initializers is used as well, but that is an
overzealous warning from initializing structs with {0} and not a
real warning.

To eliminate possible buffer overflows some strcpy,
sprintf and strcat have been changed to strlcpy,
snprintf and strlcat.

d9a4e35861 vold: Bugfixes & cleanups
- Fix issue where container-names > 64 bytes were getting truncated in the
    kernel. lo_name is only 64 bytes in length, so we now hash the container
    id via md5
  - Add 'dump' command to dump loop and devicemapper status
  - Add 'debug' command to enable more detailed logging at runtime
  - Log vold IPC arguments (minus encryption keys)
  - Fix premature return from Loop::lookupActive() and friends

fcf24fe62f vold: Add a versioned superblock to secure containers.
Add an un-encrypted superblock to the end of a secure container to
help identify the crypto cipher used. This is required in order to
provide some semblence of versioning, in case we have cause to
change the crypto type on an update - say for example switching
from software to hardware encryption, or from 128 -> a zillion
bit keys.

NOTE: This format is incompatible with previous secure containers.
After this change they will no longer be mountable.
