Previously _scratch_mount didn't check the mount status and most
tests continue to run even if the mount failed (unless test checks
for the mount status explicitly). This would result in running tests
on the underlying filesystem (usually rootfs) and implicit test
failures, and such failures can be annoying and are usually hard to
debug.
Now _fail test by default if _scratch_mount failed and introduce
_try_scratch_mount for tests that need to check mount results
themselves.

The XFS rmapbt extent swap mechanism performs an extent by extent
swap to ensure the rmapbt is rectified with the appropriate extent
owner information after the operation. This implementation suffers
from a corner case that requires extra reservation if the swap
operation results in bouncing one of the associated inodes between
extent and btree formats. When this corner case occurs, it results
in a transaction block reservation overrun and possible corruption
of the free space accounting.
This regression test provides coverage for this corner case. It
creates two files with a large enough extent count to require btree
format, regardless of inode size, and performs a sequence of extent
swaps between them with a decreasing extent count until all extents
are removed from the file(s). This ensures that one of the swaps
covers the btree <-> extent fork format boundary case.
This test reproduces fs corruption on rmapbt enabled filesystems
running on kernels without the associated extent swap fix.
