Pass down the silent flag to parse_options(). Without this fat gives
warnings when mounting some non-fat rootfs with options.

This patch removes duplicate directory scanning code from fs/fat/dir.c. The
two functions that share identical code are fat_readdirx() and
fat_search_long(). This patch also renames fat_readdirx to __fat_readdir().

During a forensic analysis on the fat file system, I found than the result for
the last access date on this file system was different between the stat
command and the istat command (package tct-utils).
The istat command display a true date (the right windows date) but the stat
primitive (so stat, find, ls command) displays a wrong date.

This patch fixes miss-sync issue on write() system call. This updates
inode attrs flags, mtime and ctime on every comit_write call, due to
locking.

Update the file systems in fs/ implementing a delete_inode() callback to
call truncate_inode_pages(). One implementation note: In developing this
patch I put the calls to truncate_inode_pages() at the very top of those
filesystems delete_inode() callbacks in order to retain the previous
behavior. I'm guessing that some of those could probably be optimized.

This speeds up directory reads for large FAT partitions, if the buffercache
has to be filled from the drive. Following values were taken from:
$ time find path_to_freshly_mounted_fat > /dev/null
on an otherwise idle system.
FAT with 16KB Clusters on IDE attached drive: Factor 2
FAT with 32KB Clusters on USB2 attached drive: Factor 10 (!)
Its less than 1/10 slower, if the buffercache is uptodate.
The patch introduces the new function fat_dir_readahead().
fat_dir_readahead() calls sb_breadahead() to readahead a whole cluster,
if the requested sector is the first one in a cluster.
It is usefull to do this, because on FAT directories occupy whole
clusters, with the exception of FAT12/FAT16 root dirs.
Readahead is only done, if the cluster's first sector is not uptodate
to avoid overhead, when the buffer cache is already uptodate.
Note that under memory pressure, the maximal byte count wasted
(read: has to be red from disk twice) is 1 cluster's size. Thats 64KB.
fat_dir_readahead() is called from fat__get_entry().
There is also an unrelated cleanup at one spot:
if (bh)
brelse(bh);
is replaced with:
brelse(bh);
brelse() can handle NULL pointer arguments by itself.

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!
