Current AVB flow in fs_mgr doesn't allow verification error even if the
device is unlocked. This makes first stage mount fail when the device
is flashed with a different-sized boot.img because there is verification
error (HASH_MISMATCH) for the boot partition.
Fix this by allowing verification error only when the device is
unlocked. Whether to enable dm-verity for HASHTREE partitions is still
controlled by the HASHTREE_DISABLED flag in the top-level vbmeta.

Test: First stage mount /vendor with AVB on a device.
Check dm-verity is enabled on /vendor.
Test: Unlock device, flash a different-sized boot.img. Boot device and check
dm-verity is still enabled on /vendor.
Test: First stage mount /vendor with AVB on a device with HASHTREE_DISABLED
is set on the top-level vbmeta, check dm-verity is not enable on /vendor.

This will let us see (a) whether the user has a legit build or something they
built themselves and (b) what Android release it corresponds to.
This isn't as useful as showing what Platform Tools release we correspond to,
but I'm planning on doing that as a separate line.

bionic's cached values for getpid/gettid can be invalid if the crashing
process manually invoked clone to create a thread or process, which
will lead the crash_dump refusing to do anything, because it sees the
actual values.
Use the getpid/gettid syscalls directly to ensure correct values on
this end.

Check the result of DecodeUid() and return failure when uids/gids are
unable to be decoded.
Also, use an error string instead of logging directly such that more
context can be added when decoding fails.

ashmem buffers start with PROT_EXEC | PROT_READ | PROT_WRITE and can
have bits individually removed (but not added) through the
ASHMEM_SET_PROT_MASK ioctl. Test that removing prot bits more than once
works, and that the kernel blocks adding prot bits.
Also test that the complementary ASHMEM_GET_PROT_MASK ioctl returns the
expected prot mask.

ashmem has in-kernel handlers for lseek() and read(), but they aren't
currently being tested.
Add tests for various seeks on a buffer containing holes. If we land
inside data, then check that we read() the expected data at that offset.

A couple of folks had trouble understanding the existing message.
Before:
8XV7N15917000596 no permissions (udev requires plugdev group membership); see [http://developer.android.com/tools/device.html]
After:
8XV7N15917000596 no permissions (user buttmunch is not in the plugdev group); see [http://developer.android.com/tools/device.html]
This also fixes a libusb regression where we wouldn't show anything for
devices where we don't have permissions.
