First, the top-level Makefile should not tell git to ignore sub-level
.gitignore files.
Second, add simple .gitignores to ignore the executables generated under
the various `tests' subdirectories.

Some compilers will complain about use of strlen() within a static array
size declaration. For this type of string, "sizeof() - 1" is equivalent
and prevents the build error.

The ubi-utils/src/ subdir is tossed as it just complicates things for no
real gain. The dictionary.h header is relocated to the ubi-utils/include/
since other headers in there need it.
The top level clean is replaced with a `find -delete` on objects, so it
might prune more than necessary, but many projects now do this sort of
thing and no one complained there.
A "mkdep" helper generates the actual rule, and the variables are used
with "foreach" to expand these automatically.
The tests subdir is updated only to reflect the ubi-utils source move.
Otherwise, it is left untouched as making that non-recursive isn't really
worth the effort.
While we're gutting things, also through in kbuild style output while
building to make things more legible.

Currently pcv macro print the error message only if we are not doing power cut
testing or if we have -v flag. But if we run without -v and an error happen
and the error code is not EROFS/EIO, pcv() does not print anything. This patch
makes it print the error message in that case as well.

Currently when we are doing UBIFS power cut emulation testing we assume that
EROFS is returned in case of an emulated power cut event. However, this is
not true and sometimes Linux returns EIO to user-space instead. Namely, this
happens when we are waiting for write-back to finish. Here is a call trace
form kernel 2.6.39-rc7:
Call Trace:
[<ffffffff810aaa77>] filemap_write_and_wait_range+0x78/0xb1
[<ffffffff8110f34d>] vfs_fsync_range+0x38/0xd3

'filemap_fdatawait_range()' returns hard-coded -EIO if a page write-back
happens with whatever error code.
Thus, this patch teaches integck to handle EIO when doing power cut emulation
testing.

This patch adds -m <mtdnum> option to integck and teaches integck to re-attach
the MTD device to UBI in case of an emulated power cut event. This is needed
for the new UBI power cut and unstable bits emulation infrastructure: when UBI
emulates a power cut the only way to recover form this is to re-attach the MTD
device.

Make the verify option -v work with power cut emulation option -e. We can
verify all operations except of writing to the file, because of write-back.
Indeed, even if we write successfully, the pages may still be in the page-cache
and if an emulated power cut happens they will be dropped, and our verification
will fail.
I am not 100% sure it is save to verify non-write operation in other FSes, but
only UBIFS has power cut emulation mode now, so we do not really care about
other FSes at this point.

All errors but write errors have corresponding CHECK(), so if something
gets wrong we fail. But in case of I/O errors we do not fail if an
unexpected error happens, which makes it difficult to trace issues.
Inject the errno checking to the pvc macro to make sure we fail if
errno is not EROFS.

Commit 1394a46213e8180e1233ca6d4811e7c77d49b1e0 was a good idea, but it
introduced a segfault - files can be unlinked and 'file->links' is NULL, it is
bad idea to unconditionally dereference it with 'file->links->name'. This patch
introduces a helper function which takes care of the situation with unlinked
files, plus it adds few assertions.

This is just a preparation - re-structure 'file_write()' to make one "success"
return point - we'll add synchronization stuff there. Also, while on it, make
it delete the file errored in truncation, not only in write. Also, move
the fsync() call to this function because it is common to all write paths.

I observes segfaults in integck test, and unfortunately I do not have the core
file to investigate the problem. But I see one possibility for the test to

The test sometimes dies due to SIGBUS because a power cut event happens when
we are writing to an mmap()'ed area. SIGBUS is very difficult to ignore, so
fix the issue simply by avoiding doing 'mmap()' operations when in power cut
testing mode.

Do not check the file-system when we are in power cut mode. Currently
we still check the FS if we did not encounter any error, and the test
fails sometimes because meanwhile write-back encounters an error and
drops pages. Disable the checking so far. It should be enabled when
we implement the 'clean' flag for files.

The integck test assumes that if the FS is rootfs then it cannot
re-mount it, otherwise it can. However, this is not true because the
tested FS can be not remountable even if it is not rootfs, e.g., if
'integck' lives on this FS and is executed from it.
This patch improves the integck logic and actually checks wheter it
is possible to re-mount the FS before starting the test.
Also, it makes sure that power cut testing is run only on re-mountable
FS, because we have to be able to clean the "corrupted" state of the
file-system.

Instead of using rand_r with own seed for operations and rand() with
global state for data it is cleaner to use rand_r with own different
states for these things. This patch eliminates 'srand()' and 'rand()'
usage.

Currently integck uses the same global random generator for everything -
for choosing the operation, generating the data, and for checking. This
makes integck to become stuck sometimes. My guess this is because of
we somehow re-set it back with srand() when checking files.
This patch makes integck use different generators for data and for
choosing operations by using rand_r() with own seed for operations.

I often need to use gdb to debug integck, or sometimes even attach
already running integck. But when it is compiled with optimizations, it
is nearly impossible to use gdb. Introduce 'debug' target to compile
integck without optimizations.
Additionally, to make the stack backtraces work, add a dirty hack to
integck.c to remove all the static keywords - this turns static
functions to non-static and makes them appear in stack backtraces.
