btrfs-progs: add mount options to btrfs-mount.5
This is a straight cut and paste from the util-linux
mount manpage into btrfs-mount.5
It's pretty much impossible for util-linux to keep up
with every filesystem out there, and Karel has more than
once expressed a wish that mount options move into fs-specific
manpages.
So, here we go.
The way btrfs asciidoc is generated, there's not a trivial
way to have both btrfs(5) and btrfs(8) so I named it btrfs-mount(5)
for now. A bit ick and I'm open to suggestions.

btrfs-progs: canonicalize pathnames for device commands
mount(8) will canonicalize pathnames before passing them to the kernel.
Links to e.g. /dev/sda will be resolved to /dev/sda. Links to /dev/dm-#
will be resolved using the name of the device mapper table to
/dev/mapper/<name>.
Btrfs will use whatever name the user passes to it, regardless of whether
it is canonical or not. That means that if a 'btrfs device ready' is
issued on any device node pointing to the original device, it will adopt
the new name instead of the name that was used during mount.
Mounting using /dev/sdb2 will result in df:
/dev/sdb2
209715200 39328
207577088 1% /mnt
lrwxrwxrwx 1 root root 4 Jun 4 13:36 /dev/whatever-i-like -> sdb2
/dev/whatever-i-like
209715200 39328
207577088 1% /mnt
Likewise, mounting with /dev/mapper/whatever and using /dev/dm-0 with a
btrfs device command results in df showing /dev/dm-0. This can happen with
multipath devices with friendly names enabled and doing something like
'partprobe' which (at least with our version) ends up issuing a 'change'
uevent on the sysfs node. That *always* uses the dm-# name, and we get
confused users.
This patch does the same canonicalization of the paths that mount does
so that we don't end up having inconsistent names reported by ->show_devices
later.

btrfs-progs: add quota group verify code
This patch adds functionality (in qgroup-verify.c) to compute bytecounts in
subvolume quota groups. The original groups are read in and stored in memory
so that after we compute our own bytecounts, we can compare them with those
on disk. A print function is provided to do this comparison and show the
results on the console.
A 'qgroup check' pass is added to btrfsck. If any subvolume quota groups
differ from what we compute, the differences for them are printed. We also
provide an option '--qgroup-report' which will run only the quota check code
and print a report on all quota groups. Other than making it possible to
verify that our qgroup changes work correctly, this mode can also be used in
xfstests for automated checking after qgroup tests.
This patch does not address the following:
- compressed counts are identical to non compressed, because kernel doesn't
make the distinction yet. Adding the code to verify compressed counts
shouldn't be hard at all though once kernel can do this.
- It is only concerned with subvolume quota groups (like most of
btrfs-progs).

It's often desirable to continue processing the send stream even if an

This change just adds a --max-errors <N> parameter, whose default value
is 1 (preserving current behaviour), that allows to tolerate N errors
