Adds a function to to insert quota rules as filesystem items.
This will then have an outward facing function that takes a
writer and a mirror of the _squota_rule struct in quota.c
and is called _parallel_restore_quota_rule. Adds testing
to make sure we are restoring a test quota.

The filesystem we are restoring into needs to be empty
and never mounted. Here we check the all of the quorum blocks
timestamps to see whether the device we are restoring into has
been mounted before. Adds a test in the test script that attempts
to restore a previously mounted device.

This tool compies a source tree (whether it's scoutfs or not)
into an offline scoutfs meta device. It has only those 2 parameters
and does a single-process walk of the tree to restore all items
while preservice as much of the metadata as possible.

After this change, all files have a single offline extent:
```
$ sudo src/filefrag-gc57857a5 -b4096 -v /mnt/scratch/top-0/file-1094
Filesystem type is: 554f4353
File size of /mnt/scratch/top-0/file-1094 is 4096 (1 block of 4096 bytes)
ext: logical_offset: physical_offset: length: expected: flags:
0: 0.. 0: 0.. 0: 1: last,unknown_loc,eof
/mnt/scratch/top-0/file-1094: 1 extent found
```

Adds a signal handler for SIGCHLD and sets up a signal handler with
SA_SIGINFO. This way we can inspect the exit code emitted by the
child and abort processing when a child process exits with an error.
Without this handler, any child process that exits with e.g. ENOSPC
will keep the parent hanging indefinitely.

This allows callers to pass in seq values for generated inodes. The
tester code initializes them now before calling, instead of being
hard set in the library.

Add a test binary that uses o_tmpfile and linkat to create a file in a
given dir. We have something similar, but it's weirdly specific to a
given test. This is a simpler building block that could be used by more
tests.

Previously the bulk_create_paths test tool used the same xattr name for
each category of xattrs it was creating.
This created a problem where two tests got their xattrs confused with
each other. The first test created a bunch of srch xattrs, failed, and
didn't clean up after itself. The second test saw these search xattrs
as its own and got very confused when there were far more srch xattrs
than it thought it had created.
This lets each test specify the srch xattr names that are created by
bulk_create_paths so that tests can work with their xattrs independent
of each other.

In newer kernels, we always get -ESTALE because the inode has been
marked immediately as deleting. Since this is expected behavior we
should not fail the test here on this error value.

There were kernels that didn't apply the current umask to inode modes
created with O_TMPFILE without acls. Let's have a test running to make
sure that we're not surprised if we come across one.

The idea here was that we'd expand the size of the struct and
valid_bytes would tell the kernel which fields were present in
userspace's struct. That doesn't combine well with the ioctl convention
of having the size of the type baked into the ioctl number. We'll
remove this to make the world less surprising. If we expand the
interface we'd add additional ioctls and types.

The stage_tmpfile test util was written when fallocate didn't update
data_version for size extensions. It is more correct to get the
data_version after fallocate changes data_versions for however many
transactions, extent allocations, and i_size extensions it took to
allocate space.

Support O_TMPFILE: Create an unlinked file and put it on the orphan list.
If it ever gains a link, take it off the orphan list.
Change MOVE_BLOCKS ioctl to allow moving blocks into offline extent ranges.
Ioctl callers must set a new flag to enable this operation mode.
RH-compat: tmpfile support it actually backported by RH into 3.10 kernel.
We need to use some of their kabi-maintaining wrappers to use it:
use a struct inode_operations_wrapper instead of base struct
inode_operations, set S_IOPS_WRAPPER flag in i_flags. This lets
RH's modified vfs_tmpfile() find our tmpfile fn pointer.
Add a test that tests both creating tmpfiles as well as moving their
contents into a destination file via MOVE_BLOCKS.
xfstests common/004 now runs because tmpfile is supported.

bulk_create_paths was inspired by createmany when it was outputting
status lines every 10000 files. That's far too often if we're creating
files very quickly. And it only tried to output a line after entire
directories, so output could stall for very large directories.
Behave more inline with vmstat, iostat, etc, and output a line at a
regular time interval.

Add options to bulk_create_paths for creating xattrs as we create files.
We can create normal xattrs, or .srch. tagged xattrs where all, some, or
none of the files share the same xattr name.
