Helpers to get a block device size in bytes or 512 byte sectors,
using BLKGETSIZE64 and returning value of uint64_t type.
This also removes get_blkdev_size().

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.

Vold is updated to create package specific sandboxes for primary
volume and mount them at
"/mnt/user/<user-id>/package/<package-name>/<primary-label>".
This will later be mounted at /storage when a new process starts.
Bug: 111890351
Test: Manually verified that a package has access to "/sdcard" and
"/storage/emulated/0", both of which are just the package specific
sandboxes and the package doesn't have access to other sandboxes
and can't see other package names.

Our external partitions have no crypto header/footer, so we
only get the keysize and key. Our code has been implicitly
assuming that this keysize off of disk matches the crypto
type we have in our code (and thus matches the keysize our
code is using as well). We now make this assumption
explicit, and check for this and no longer allow external
code to pass a keysize in to cryptfs.

Several partners have been requesting exFAT support. Android doesn't
natively support exFAT, but we're at least willing to try mounting an
exFAT filesystem if we detect the Linux kernel supports it, and if
helper binaries are present.
This CL is simple scaffolding, and it provides no actual
implementation of exFAT.
Test: builds, boots

We've finished all the underlying work to support adoptable storage
on FBE devices, so remove the code that was disabling it by default.
To aid debugging, support blocking move commands (so that we log
the stdout) via a system property, so we don't have to recompile
end user devices stuck in funky states.

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]

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.

the dev_t won't actually change. To avoid getting waiting forever
and triggering the watchdog, timeout after 5 seconds.

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.
