Do not die in 'dir_new()' if it cannot create a new directory and
this is not because of ENOSPC. Return NULL for all errors.
Note, not all callers are ready to properly handle all errors so far.

Modify the 'rm_minus_rf_dir()' function to return -1 in case of any
errors during deletions. Make 'integck()' handle the errors. Also
introduce a 'pcv()' function to print error message if -v command
line option was specified.

Introduce new command line arguments for power cut testing:

The 'make_name()' function assumes that the maxumum file name length

Remove the final dependency on the common code - the CHECK() macro.
Now we are finally independent. The reason we needed this is that
we are going to improve integck to handle errors more gracefully,
in order to support failure testing better. And this requires changes
in the common code, but it is ancient and shared by many tests, and
we do not want to touch it. So we better make integck independent
and concentrate on integck only.
This patch also removes Makefile dependencies. And while on it, remove
the broken 'tests' target.

Do not use the shared 'tests_random_no()' function but use our own

Many of standard C libraries return 0 on success and -1 on failure.
Currently integck mostly checks for failure by comparing with -1, like:
CHECK(fsync(fd) != -1) /* Don't die if not failure */
but in some places the check is like
CHECK(fsync(fd) == 0) /* Don't die if success */
This patch harmonizes this an makes integck to use the second style
which seems to be more logical. Besides, the binary is smaller in
this case:
[dedekind@eru fs-tests (master)]$ size integrity/integck-old
text data bss dec hex filename
44677 1200 37408 83285 14555 integrity/integck
[dedekind@eru fs-tests (master)]$ size integrity/integck-new
text data bss dec hex filename
44661 1200 37408 83269 14545 integrity/integck

Do not use shared 'tests_clear_dir()' function which removes a directory
tree recursively, but instead use own implementation. This is because
I'm trying to make integck independend on the shared code because I
need this to do further improvements.

Turn the 'void integck(void)' function into 'static int integck(void)'.
We need to teach the test to gracefully handle some error cases like
'EROFS' instead of failing and exiting straight away. And the ground
work for this is making all functions return errors. This is the first
tiny step in this direction.

This is a clean-up patch which:
1. Simplifies copy_string by useng strdup instead of malloc
2. Adds an assertion which checks the input parameter agains NULL,
instead of checking it.
3. Re-names it to dup_string which looks more readable to me.

Instead of using shared command line arguments parsing routine
implement own. The reason is that I want to add more parameters,
which are integck-specific. Also, longer-term plan is to make
integck independent of the common tests.c file.

Currently integck assumes that by default the file-system cannot
do shared writable mmap-ing and does not preserve accurate file
size after ENOSPC errors. And then it overrides these default
settings if this is UBIFS.
But it seems that only JFFS2 has those limitations. So make the
defaults to be the opposite and override them for JFFS2 only.

The 'struct write_info' data strucutre records information about
truncation, and has a separate integer field to specify if this is
a truncation or not. But it is too wasteful because we have huge
amount of these objects.
But it is easy to notice that the 'random_seed' field is not used
for truncation records, so we can use that as the truncation flag.
This patch introduces MAX_RANDOM_SEED macro and when the 'random_seed'
field is greater than that, we treat it as the truncation flag.

Currently integck uses the 'random_offset' filed to store the new file
length sometimes, thus abusing this field. But we can do this nicer -
introduce an anonymous union and add 'new_length' filed which will be
used instead of 'random_offset' to make the code look nicer.

The 'check_run_no' field does not have to be 64-bit, it can be
32-bit instead and we can save 4 bytes per object. Actually, it
could also be 16-bit, and we could make link_count 16-bit as well,
but that would need a bit more work.

Turn "int checked" flag into 'char' flag to lessen memory
consumption a bit. Indeed, the test allocates a lot of these
data objects, so the size decrease from 36 to 32 bytes on
32-bit platforms is good to have.

The 'link_new()' function has only one user, and the user checks
that the third 'file' argument is non NULL, so remove this check
from 'link_new()'. Let's be consistent and assume the 3rd argument
is never NULL, just like the first and the second ones.
This is just a minor improvement.

Instead of using named union 'entry' in 'struct dir_entry_info'
