Create a 2 device raid1 filesystem, fill with some data, delete one
device (the device node must not exist) and try to dump a filesystem
image.

Current code of btrfs-convert have a bug of thread conflict, which caused
invalid memory accessing between threads, and make program panic.
This patch add a test item for above bug, as:

Note that this bug is not happened every time, especilly in slow
device as loop(slow cpu with fast block device is likely to trigger).
I set loop count to 20 to make bug happened in 90% tests.

This code block is used several tests, move it to ./common and add a
helper.

Previously in 'filesystem resize get_min_size', now
'inspect-internal min-dev-size'. We'd like to avoid cluttering the
'resize' syntax further.
The test has been updated to exercise the new option.

Currently there is not way for a user to know what is the minimum size a
device of a btrfs filesystem can be resized to. Sometimes the value of
total allocated space (sum of all allocated chunks/device extents), which
can be parsed from 'btrfs filesystem show' and 'btrfs filesystem usage',
works as the minimum size, but sometimes it does not, namely when device
extents have to relocated to holes (unallocated space) within the new
size of the device (the total allocated space sum).
This change adds the ability to reliably compute such minimum value and
extents 'btrfs filesystem resize' with the following syntax to get such
value:
btrfs filesystem resize [devid:]get_min_size

Simple test to verify that the log_root is reset after the command, but
we yet need to provide a testing image with log_root set to something
sensible or crafted images with borked log_root pointer.

A sample test for the misc-test category. Verify that btrfstune sets the
requested fs features. Now implemented extrefs, skinny-metadata and
seeding.
