btrfs-progs: convert: use search_cache_extent in migrate_one_reserved_range
When we are looking for extents in migrate_one_reserved_range, it's likely
that there will be multiple extents that fall into the 0-1MB range.
If lookup_cache_extent is called with a range that covers multiple cache
entries, it will return the first entry it encounters while searching
from the top of the tree that happens to fall in that range. That
means that we can end up skipping regions within that range, resulting
in a file system image that can't be rolled back since it wasn't
all migrated properly.
This is reproducible using convert-tests/008-readonly-image. There was
a range from 0-160kB, but the only entry that was returned began at
~ 280kB.
The fix is to use search_cache_extent to iterate through multiple regions
within that range.

btrfs-progs: convert: properly handle reserved ranges while iterating files
Commit
522ef705e38 (btrfs-progs: convert: Introduce function to calculate
the available space) changed how we handle migrating file data so that
we never have btrfs space associated with the reserved ranges. This
works pretty well and when we iterate over the file blocks, the
associations are redirected to the migrated locations.
This commit missed the case in block_iterate_proc where we just check
for intersection with a superblock location before looking up a block
group. intersect_with_sb checks to see if the range intersects with
a stripe containing a superblock but, in fact, we've reserved the
full 0-1MB range at the start of the disk. So a file block located
at e.g. 160kB will fall in the reserved region but won't be excepted
in block_iterate_block. We ultimately hit a BUG_ON when we fail
to look up the block group for that location.
This is reproducible using convert-tests/003-ext4-basic.
The fix is to have intersect_with_sb and block_iterate_proc understand
the full size of the reserved ranges. Since we use the range to
determine the boundary for the block iterator, let's just return the
boundary. 0 isn't a valid boundary and means that we proceed normally
with block group lookup.

btrfs-progs: subvol show: add support to search subvolume by rootid or uuid
Unless the top level is mounted there is no way to know the
details of all the subvolume. For example:
mount -o subvol=sv1/newsv1 /dev/sdb /btrfs
btrfs su list /btrfs
ID 257 gen 12 top level 5 path sv1
ID 258 gen 9 top level 257 path sv1/snap
ID 259 gen 11 top level 257 path sv1/newsv1
You can't subvol show for sv1 and sv1/snap as its paths aren't
accessible to the user unless the its top level is mounted.
This patch adds two new options to the existing btrfs subvol show
cli. They are --rootid/-r or --uuid/-u, with this now the user will
be able to look for a subvolume using the rootid OR the uuid.

The fix here was to put most of the main loop of restore_worker

in that case the count of remaining items (nritems - slot - 1) gets
negative. That is then casted to (unsigned long len), which leads to the
observed crash.
Change the tests before the move to handle only the non-corrupted case,
were slow < nritems.
This does not fix the corruption, but allows btrfsck to finish without
crashing.

btrfs-progs: Refactor read_tree_block to get rid of btrfs_root
The only reasom read_tree_block() needs a btrfs_root parameter is to get
its node/sector size.
And long ago, I have already introduced a compactible interface,
read_tree_block_fs_info() to pass btrfs_fs_info instead of btrfs_root.
Since we have cleaned up all root->sector/node/stripesize users, we
should be OK to refactor read_tree_block() function.

btrfs-progs: Refactor btrfs_root paramters in btrfs-corrupt-block.c
Refactor the following functions and its callers to get rid of
incorrectly passed btrfs_root parameters:
1) corrupt_keys()
2) corrupt_metadata_block()
The only reason passing btrfs_root for them is to get block sizes.

btrfs-progs: Remove block size members in btrfs_root
Finally, we can get rid of per tree block size members now.
