Fixing signed/unsigned comparison warnings
Clang turned up some signed/unsigned comparison warnings. These warnings
have been fixed by cleaning up sdcard slightly:
- Don't use negative numbers for invalid gid/uid.
- sdcard takes a fixed number of arguments now so assert on that instead
of using a for loop.
- Also fixed usage string to reflect this fact.

Make sdcard daemon multi-threaded.
The essential idea here is that a handler thread only needs to
hold a lock on the global node table while it is manipulating
nodes. The actual I/O operation is then performed without
holding any locks.
By default, we use 2 threads but this can be configured on the
command-line. Work is sheduled somewhat arbitrarily by the
handler threads. Whichever thread happens to read() the next
request first wins the right process it. This policy is very
simple but potentially wastes threads when there isn't much
work to be done. We can always improve this later if needed.

More code cleanup.
Use constants to specify MAX_READ and MAX_WRITE buffer sizes and
use that to determine the size of the buffers that we need.
Be more careful about how the request header and data payload are
extracted. For example, the old code did len -= hdr->len, but
since len == hdr->len, this value was always 0. It turns out we
didn't use len thereafter, but we might want to for sanity checking
incoming requests.
Use const to make it clearer what data is coming out of the request.
Removed spurious error reply from FUSE_WRITE. It serves no purpose
and is ignored by the kernel.

sdcard: Remove lower case squashing of file names
sdcard daemon will now create new files and directories using
the actual name passed in by the client.
For existing files, sdcard will do case insensitive matching
when case sensitive lookup fails.

sdcard: Fix lower case squashing for case insensitivity support.
The fuse layer in the kernel does not support case insensitive file systems.
But the sdcard daemon's fuse_lookup was returning the same file object for
different file names, which caused problems in the kernel fuse layer's dcache,
resulting in EBUSY errors if the same directory was opened twice under different
names differing only by case.
To fix this, the sdcard daemon will return different file objects for files or directories
that differ only by case. Now the squashing occurs only in the interaction between
the sdcard daemon and the underlying file system in /data/media, and sdcard maintains
the illusion for the kernel fuse layer that there are two separate files.
Example: Suppose both /mnt/sdcard/foo.txt and /mnt/sdcard/FOO.TXT are opened.
Previously, the sdcard would squash this to a single node, and return the same
node to the kernel fuse implementation twice, and would open the underlying file
/data/media/foo.txt only once. Now sdcard will create two separate nodes will open
/data/media/foo.txt twice, once for mnt/sdcard/foo.txt and again for /mnt/sdcard/FOO.TXT.

Properly reflect RENAME ops in FUSE internal state
In response to a RENAME, we actually need to rename and move the virtual
node. To support this, filenames are now allocated separately, as reallocing
the whole node to accommodate a longer filename would break the direct
mapping of fhs and inodes to fuse pointers.

directory permissions (all files are given fixed owner, group, and
permissions at creation, owner, group, and permissions are not
changeable, symlinks and hardlinks are not createable, etc.
usage: sdcard <path> <uid> <gid>
It must be run as root, but will change to uid/gid as soon as it
mounts a filesystem on /sdcard. It will refuse to run if uid or
gid are zero.
