recovery: Implement a volume manager
This is a copy of the pre-binderized vold which has been converted to
use direct calls instead of sockets and stripped down to only what is
needed to support recovery.
Includes:
* Replace security_context_t type
security_context_t has been marked as deprecated in libselinux from
version 3.2. Update to the `char*` type.
Bug: 190808996
Test: m
Change-Id: I6f40e161251c79893d41e12c368715736578aacc
* recovery: volmgr: remove unused IsSupported
Change-Id: If8206658fdfb6108221806c09c99bf0a30f4a586
Signed-off-by: Jesse Chan <jc@lineageos.org>
* recovery: volmgr: remove filesystem checks
Those checks are not strictly necessary and we are
not building fsck tools for recovery for now.
Remove those checks so volmgr can be useful.

* recovery: fixup `EmulatedVolume creating`
Avoid dangling pointer. Instead of pointing to FstabEntry create copy.
Change-Id: I57f76006db09a6add2c173f43175f0f6b848d87b
* recovery: fix volmgr cleaning up
Don't reset pointer to netlink manager
Delete disks in stop() rather then in ~VolumeManager
Call destroy() before deleting disks cause delete expects the
disk to be destroyed
Clear the lists or we would read garbage data on the next scan

* recovery: handle interrupts in apply update menu
