The functionality of ext3 is fully supported by ext4 driver. Major
distributions (SUSE, RedHat) already use ext4 driver to handle ext3
filesystems for quite some time. There is some ugliness in mm resulting
from jbd cleaning buffers in a dirty page without cleaning page dirty
bit and also support for buffer bouncing in the block layer when stable
pages are required is there only because of jbd. So let's remove the
ext3 driver. This saves us some 28k lines of duplicated code.

Convert ext3_count_free() to use memweight() instead of table lookup
based counting clear bits implementation. This change only affects the
code segments enabled by EXT3FS_DEBUG.
Note that this memweight() call can't be replaced with a single
bitmap_weight() call, although the pointer to the memory area is aligned
to long-word boundary. Because the size of the memory area may not be a
multiple of BITS_PER_LONG, then it returns wrong value on big-endian
architecture.
This also includes the following changes.
- Remove unnecessary map == NULL check in ext3_count_free() which
always takes non-null pointer as the memory area.
- Fix printk format warning that only reveals with EXT3FS_DEBUG.

When EXT3FS_DEBUG is #define-d, the compile breaks due to #include file
issues.

This patch contains the following cleanups:
- there's no need for ext3_count_free() #ifndef EXT3FS_DEBUG
- having prototypes for ext3_count_free() in two different headers is
nonsense

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
