Remove lots of "extern C" and "ifdef __cplusplus" which are no longer
needed now all of vold is C++. Also turn on the cert-err58-cpp warning
we once had to disable.

Protect all per-volume-per-user keys with a per-volume key, which is
forgotten when the volume is forgotten. This means that the user's key
is securely lost even when their storage is encrypted at forgetting
time.

If it's not a keymaster key, don't try to invalidate or delete the key
blob.

When we set up encryption on real volumes - not just /data - we should
give them their own keys, so that these keys can be deleted when the
volume is forgotten. Also, we must choose the encryption modes
differently, since ICE encryption which works on /data may not work on
such volumes.

Test: boot device, add SD card, check modes.

Minimize overhead in boot by replacing shell script invoked multiple

FDE keys are indexed using the partition GUID, while FBE keys will be
indexed using the filesystem UUID, so pass both of those identifiers
along when forgetting a volume.

I want to use Utils in another executable, so breaking this link.

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.

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.

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.
