Btrfs-progs v0.17 for 2.6.29-rc1 mainline merge

Update version.sh to v0.16

Verify parent generation number on btree reads

Fix btrfs-convert's large file support.

This patch add ext2_inode.i_size_high into account when calculating regular
file's size in btrfs-convert,  which makes it deal with large files bigger than
4GB properly.

CRC32C big endian bugs...

The CRC32C implementation in the btrfs progs is different from the one
in the kernel, so obviously nothing can possibly work on big-endian.

Update magic

Remove kernel-space header in btrfs-progs

When porting ctree.c in btrfs kernel module to btrfs-progs, I forgot
to remove a kernel-space header.  This may cause compile error on some
system.
