We were auto-generating it before. The problem was that the autogeneration
tool we were using was called "copy, paste, and edit". Let's use a more
sensible solution.

v2 by Samuel Iglesias <siglesias@igalia.com>
- Remove format_pack.c as it is now autogenerated
- Add usage of INDENT_FLAGS in Makefile.am
- Remove trailing blank line
v3 by Samuel Iglesias <siglesias@igalia.com>
- Merge format_convert.py into format_parser.py
- Adapt pack_*_* function generations
- Fix out-of-tree build
v4 by Samuel Iglesias <siglesias@igalia.com>
- _get_datatype() is now a helper function
v5 by Samuel Iglesias <siglesias@igalia.com>
- format_pack.c.mako is now format_pack.py, with the template code
inlined. It now auto-generates format_pack.c
- Simplify Makefile.am change.
- Modify SConscript to build format_pack.c with scons.
- Remove run_mako.py
- Add format_pack.c to gitignore
v6 by Samuel Iglesias <siglesias@igalia.com>:
- Don't allow float to non-normalized integer format conversions.
- Add non-normalized formats support for ubyte packing functions. Merge
the previously separated patch.

The basic concept for the format parser was taken from the format CSV
parser in gallium/auxilliary/util. However, this one has been altered in a
number of ways:
* Removed big endian vs. little endian stuff (mesa doesn't need it)
* Better documentation: Almost every method has a full docstring
* An actual Swizzle class with methods for composition and inverses
* Over-all cleaner (in my opinion) implementation and class interactions
* A few bug fixes
