This commit is a preparation for a subsequent bugfix. We introduce a
counter for categorized lprops.

UBIFS currently prints a lot of information when it mounts a volume, which
bothers some people. Make it less chatty - print only important information
by default.
Get rid of 'dbg_msg()' macro completely.

Have the debugging stuff always compiled-in instead. It simplifies maintanance

This commit re-names all functions which dump something from "dbg_dump_*()" to
"ubifs_dump_*()". This is done for consistency with UBI and because this way it
will be more logical once we remove the debugging sompilation option.

In case of errors we almost always need the stack dump - it makes no sense
to compile it out. Remove the 'dbg_dump_stack()' function completely.

"heap" is initialized twice. I removed the first one, because it makes
Smatch complain that we use "new_cat" as an offset before checking it.
This doesn't change how the code works, it's just a cleanup.

This patch introduces helper functions for all debugging checks, so instead of
doing
if (!(ubifs_chk_flags & UBIFS_CHK_GEN))
we now do
if (!dbg_is_chk_gen(c))
This is a preparation to further changes where the flags will go away, and
we'll need to only change the helper functions, but the code which utilizes
them won't be touched.
At the same time this patch removes 'dbg_force_in_the_gaps()',
'dbg_force_in_the_gaps_enabled()', and dbg_failure_mode helpers for
consistency.

The UBIFS lpt tree is in many aspects similar to the TNC tree, and we have
similar flags for these trees. And by mistake we use the COW_ZNODE flag for
LPT in some places, instead of the right flag COW_CNODE. And this works
only because these two constants have the same value.
This patch makes all the LPT code to use COW_CNODE and also changes COW_CNODE
constant value to make sure we do not misuse the flags any more.

Now we return all errors from 'scan_check_cb()' directly, so we do not need
'struct scan_check_data' any more, and this patch removes it.

When doing the lprops extra check ('dbg_check_lprops()') we scan whole media.
We even scan empty and freeable LEBs which may contain garbage, which we handle
after scanning. This patch teach the lprops checking function
('scan_check_cb()') to avoid scanning for free and freeable LEBs and save time.

This patch fixes a brown-paperbag bug which was introduced by me:
I used incorrect "GFP_KERNEL | GFP_NOFS" allocation flags to make
sure my allocations do not cause write-back. But the correct form
is "GFP_NOFS".

Instead of using pre-allocated 'c->dbg->buf' buffer in
'scan_check_cb()', dynamically allocate it when needed. The intend
is to get rid of the pre-allocated 'c->dbg->buf' buffer and save
128KiB of RAM (or more if PEB size is larger). Indeed, currently we
allocate this memory even if the user never enables any self-check,
which is wasteful.

At the moment UBIFS print large and scary error messages and
flash dumps in case of nearly any corruption, even if it is
a recoverable corruption. For example, if the master node is
corrupted, ubifs_scan() prints error dumps, then UBIFS recovers
just fine and goes on.
This patch makes UBIFS print scary error messages only in
real cases, which are not recoverable. It adds 'quiet' argument
to the 'ubifs_scan()' function, so the caller may ask 'ubi_scan()'
not to print error messages if the caller is able to do recovery.

When freeing the c->idx_lebs list, we have to release the LEBs as well,
because we might be called from mount to read-only mode code. Otherwise
the LEBs stay taken forever, which may cause problems when we re-mount
back ro RW mode.

stuff inside. This is cleaner than having debugging stuff

'ubifs_get_lprops()' and 'ubifs_release_lprops()' basically wrap
mutex lock and unlock. We have them because we want lprops subsystem
be separate and as independent as possible. And we planned better
locking rules for lprops.
Anyway, because they are short, it is better to inline them.

This commit adds a reserved pool size print and tweaks the
prints to make them look nicer.
It also fixes and cleans-up some comments.
Additionally, it deletes some blank lines to make the code look
a little nicer.
In other words, nothing essential.
