the initial implementation of file truncation. Now both open(2)ing
a file with the O_TRUNC flag and the {,f}truncate(2) system calls
will resize a file appropriately. The limitations are that only
uncompressed and unencrypted files are supported. Also, there is
only very limited support for highly fragmented files (the ones whose
$DATA attribute is split into multiple attribute extents).

checked and set in the ntfs inode as done for compressed files
and the compressed size needs to be used for vfs inode->i_blocks
instead of the allocated size, again, as done for compressed files.

mft record for resident attributes (fs/ntfs/inode.c).
- Small readability cleanup to use "a" instead of "ctx->attr"
everywhere (fs/ntfs/inode.c).

enable bit which is set appropriately and a per inode sparse disable
bit which is preset on some system file inodes as appropriate.
- Enforce that sparse support is disabled on NTFS volumes pre 3.0.

cached value everywhere. Cache the initialized_size in the same way
and protect the critical region where the two sizes are read using the
new size_lock of the ntfs inode.
- Add the new size_lock to the ntfs_inode structure (fs/ntfs/inode.h)
and initialize it (fs/ntfs/inode.c).

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!
