[PATCH 0/3 v2] Add btrfs ioctl support

[Jeff Mahoney]

Hi all -

This short series adds support for the btrfs ioctls.  Its structures
make heavy use of __u64 so rather than cast every single member, I added
new PRI* macros to print them properly.  It also uses 64-bit flags and
defines values that are larger than can be described by a 32-bit
variable, so I've converted xlat to use a 64-bit val field internally
and added 64-bit versions to API functions as needed.

Thanks, Dmitry, for the review.

Changes since v1:
- Change addflags, printflags, and sprintflags to use unsigned int vals.
- Introduce 64-bit variants for all three.
- Convert all three to wrappers around the 64-bit versions
- Use pointers to uint64_ts instead of casting ints for bsearch
- Use SIZEOF_LONG instead of BITS_PER_LONG
- Fix missing comma for ioctls that return a signed int value
- Don't test for exiting(tcp) if we've already returned a nonzero value
  in entering mode
- Use stdint types when defining structs
- Don't define separate macros for testing structs
- Add UUID_STRING_SIZE macro
- Don't test for error if umove* will be called immediately afterward
- Various style fixes
- Don't assume btrfs.h will be available

Thanks,

-Jeff
