file_system/fat: Rework driver for fs_shell support

* Introduce fat_shell for build system fat manipulation
* Will theoretically let us do away with mtools when we
have another internal tool for partition manipulation

fat: correctly read lowercase 8.3 filenames

Historically, FAT stored filenames as uppercase. Modern windows versions
will however be case-preserving. As a special case, all-uppercase files
from old FAT filesystems will be converted to all-lowercase. There are
two flags (one for filename and one for extension) indicating that this
should be done. We did not make the distinction between these two flags
when reading a filename.

We still don't set the flags properly when writing files, but we always
provide a long file name (even if the name would fit in the 8.3 pattern
for a short one, so when reading back our own entries, we should always
use the long filename and be safe.

fat: Print format, whitespace and style cleanup only.

I took the liberty to convert most of the debug output from hex to
decimal as unprefixed hex values are rather confusing.

Just a bit of cleanup, remove trailing whitespace mostly. No functional changes.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24995 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed "dos" file system to "fat".
