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.

We do not have to store boolean flags in 'int' variables which
consume 4 bytes each, we can store those in bit-fields instead.

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'
and having to type long 'entry->entry.file', 'entry->entry.symlink',
etc, use anonymous union which makes the syntax simpler: 'entry->file',
'entry->symlink', etc.

The malloc function returns 'void *', so it is not necessary to
cast it when assigning. This is just a small clean-up patch.

The integck test often allocates memory and fills it with zeroes.
Introduce a helper function for this frequent operation.
This is just a clean-up patch which makes the code 23 lines shorter.

The integck tests re-mounts the file-system from time to time
and checks the integrity afterwords. And it re-mounts always
the same-way: unmount and then mount R/W back. However, it is
better to do it differently some times, e.g.:
* re-mount R/O then re-mount R/W
* unmount then mount R/W
* both of the above
* unmount, mount R/O, then re-mount R/W
* etc.
This will give better test coverage. This patch does exactly
that by improving the 'tests_remount()' function.

Fix the following compilation warning:
perf.c: In function ‘perf’:
perf.c:144: warning: format ‘%lld’ expects type ‘long long int’, but argument 2 has type ‘int64_t’

Fix the following compilation warnings:
test_1.c: In function ‘test_1’:
test_1.c:67:4: warning: format ‘%llu’ expects type ‘long long unsigned int’, but argument 3 has type ‘uint64_t’
test_1.c:88:3: warning: format ‘%llu’ expects type ‘long long unsigned int’, but argument 3 has type ‘uint64_t’
The fix is to cast the argument with (unsigned long long).

Instead, create a "new-utils" subdirectory and move my work
there.

When the integrity test encounters a file that does not contain
the expected data, it lists the data that it expected to find
in terms of writes to the file.
Now the test also displays a list of "raw" writes that includes
writes that have been truncated away, or completely overwritten
by other writes.
The test also now displays the pid because it is used as the
initial random seed.
