The previous commit fixed a problem in FAT code where going back to the
root directory using '..' wouldn't work correctly on FAT12 or FAT16.
Add a test to exercise this case (which was once fixed in commit
18a10d46f26 "fat: handle paths that include ../" but reintroduced due to
the directory iterator refactoring).
This test only very barely catches the problem - without the fix the
size command still gives valid output but the additional spurious
"Invalid FAT entry" error message makes it not get caught in the
'egrep -A3 ' output. I tried to make a proper test that grows the root
directory to two clusters lots of with dummy files but that causes the
write tests to crash the sandbox totally...

Currently we can only test FAT32 which is the default FAT version that
mkfs.vfat creates by default. Instead make it explicitly create either a
FAT16 or a FAT32 volume. This allows us to exercise more code, for
instance the root directory handling is done differently in FAT32 than
the older FATs.
Adding FAT12 support is a much bigger job since the test creates a 2.5GB
file and the FAT12 maximum partition size is way smaller than that.

Thanks to Stefan Brüns we have more tests and a few more passes too,
update the expected output now.

<path>/<fname> and <path>/./<fname> should reference the same file.

This is a regression test for a crash happening if the first dirent
in the block matches. Code tried to access a predecessor entry which
does not exist.
The crash happened for any block, but "." is always the first entry in
the first directory block and thus easy to check for.

ext4 and fat code emit some diagnostic messages during command execution.
These additional lines force a match window size which strictly is not
necessary.

The write file is created from $SMALL_FILE by appending ".w" on all
other occurences in the code.

Instead of providing the full path, specify directory and filename
separately. This allows to specify intermediate directories, required
for some additional tests.

The fs-test.sh script expected there to be a \n\r style newline at the
end of the output. This is no longer the case, so use 'tr' to remove the
\r that we get.

- Use "mkdir -p" to avoid errors when intermediate directories are
missing.
- Fall back to "dd" when "fallocate" fails. For example, fallocate isn't
supported on ext4.
- Add error checking for test image generation. Without this, the test
simply plows on spewing all kinds of errors which are hard to
immediately root-cause.

Check the result code of all command that are executed. Without this,
if the fallocate invocation fails (this feature is not supported on ext3
filesystems for example) then a zero-length output file will be created,
and subsequent the mkfs and mount invocations will fail, which will cause
the subsequent dd invocation to attempt to fill up the host's entire free
disk space. That's not a nice user experience!
Related, if fallocate does fail, try to create the test disk image using
dd instead. That should work everywhere.

In the following snippet:
if [ ! -x `which $prereq` ]; then
When $prereq does not exist, `which $prereq` evaluates to the empty string,
which results in *no* argument being passed to the -x operator, which then
evaluates to true, which is the equivalent of the prereq having been found. In
order for this to fail as expected, we must pass an empty argument, which then
causes -x to fail. Do this by wrapping the `` in quotes so there's always an
argument to -x, even if the value of the argument is zero-length.

In my patch series to replace fs/fat with "ff.c", I enhanced ff.c to
optimize file reading, so that reads of contiguous clusters are submitted
to the IO device as a single read. This test attempts to torture-test
edge-cases of that enhancement.
BTW, the only way I found to validate that this script actually does
create non-contiguous files was to manually inspect the FAT bitmap in a
hex dump of the FAT image. hdparm --fibmap doesn't work on loop-mounted
filesystems. filefrag -v -e seems to lie about files being contiguous
when they aren't.

With the changes in 7a3e70c we now get read(2) behavior so trying to
read 2MB with 1MB left in the file results in 1MB read and a warning.
We update the test logic here to make sure we read back 1MB as expected.
This change however changes the overall summary as while EXT4 continues
to not have offset support the test now fails when expected to pass
rather than fails when expected to fail (and we report that as pass).

- Re-direct stderr into the log files, so any errors U-Boot emits are
visible in the logs. This is relevant if the "reset" shell command
attempts to report that it's not supported on the sandbox board.
- Fix test_fs_nonfs() to name the files it created differently for each
invocation. Otherwise, the logs from different tests overwrite
each-other.
