When using dynamic partitions, the blk_device field in fstab_rec must be
translated to a /dev/block/dm-N node with
fs_mgr_update_logical_partition. However, init will not have created
these nodes to begin with since CreateLogicalPartitions is not called in
recovery. This patch addresses both issues.
Note that flashing system through fastbootd will not work while /system is
mounted.

The earlier commit in 2dfc1a3898
unintentionally changed the behavior. It gives a different result when
looking up non-existent mount points (e.g. /cache on marlin).
The logic behind volume_for_path("/xyz") is unclear:
- It's fine to return non-null value if it's called by
ensure_path_mounted() before accessing that file "/xyz". (Just based
on the function name, we're not actually having this case.)
- It should return nullptr if the caller is interested in the existence
of that particular mount point "/xyz".
This CL renames the function to volume_for_mount_point(), which does an
exact match by querying the given mount point from libfs_mgr. The former
volume_for_path() has been moved down to function scope for serving
ensure_path_mounted() only.

Commit cc323958f99e40fea06c511656c69c0b2e2d47f7 in system/core has
changed fs_mgr_get_entry_for_mount_point() to do an exact match only,
which breaks the behavior in volume_for_path().
This CL changes the volume_for_path() implementation to parse and pass
prefixes locally. For a given path like "/cache/recovery/last_log", it
will in turn attempt the prefixes of "/cache/recovery/last_log",
"/cache/recovery", "/cache", "/" and return the first hit.

While calculating volume size, get_block_device_size() returns
u64 value but the returned value is assigned in ssize_t variable.
This may cause integer overflow if the volume size is beyond
ssize_t limit.
Use int64_t instead of ssize_t in get_file_size() and explicitly check
for overflow to fix the issue.

'-S file_contexts' is also no longer required by e2fsdroid, since commit

When system images contain the root directory, there is no entry of
"/system" in the fstab. Change it to look for "/" instead if
ro.build.system_root_image is true. We actually mount the partition
to /system_root instead, and create a symlink to /system_root/system
for /system. This allows "adb shell" to work properly.
