Create a helper function to create a populated FS image and dump the
metadata into a file on the test device, with the purpose of allowing
future (fuzzer) invocations of _populate_fs use the cached metadata to
save time.

Move some fuzzing helper functions into a new common/fuzzy file.
We'll add a lot more fuzzing helpers in subsequent patches.

There were some silly errors in _scratch_fuzz_modify such that it
wasn't really doing much of anything because of undefined variables.
(Sloppy refactoring when converting xfsfuzz.sh into xfstests.)

Be a little more flexible in how much we fill up a pre-populated
filesystem. For the field fuzzing tests, we don't need the extra
space/inode usage and therefore won't want much at all.

Back when I created common/populate, I thought it was sufficient to
_require the tools that the populate functions need in the main
file. This turned out to be a bit sloppy, so move them into a
helper function and call it from everything that uses populate.

We have three new metadata types -- rmapbt, rtrmapbt, and refcountbt.
Ensure that we populate the scratch fs with all three.

When enabling btrfs compression, original codes can not fill fs
correctly, here we introduce _fill_fs() in common/rc, which'll keep
creating and writing files until enospc error occurs. Note _fill_fs
is copied from tests/generic/256, but with some minor modifications.

xfs_db requires us to pass in the log device, if any; this can be
accomplished via _scratch_xfs_db_options (if we're operating on the
scratch device, anyway). However, many of the tests/xfs/ scripts
pass only $SCRATCH_DEV directly, so they'll fail if we test with an
external log. Fix that by adding a new _scratch_xfs_db helper.

_scratch_ext4_populate and _scratch_xfs_populate try to create
devices directory in xfstests/, so if we run xfs/083 or ext4/006
twice, it'll fail, fix this issue.
