Some SRGB formats don't get the expected linear counterparts in
isl_format_srgb_to_linear() in the generated isl_format_layout.c.
The replace() of string in python returns the unchanged input
string when no replacement occurred, so the first rule
('_SRGB', '') returns the original SRGB format name that passes
the following check unintendedly.
Another quirk is needed for a pair of formats not following
the patterns of other formats.

The format enum space isn't necessarily contiguous so we can't assume
that if it's in the table it's valid. We need to check something.

Putting a const char * in the struct means it's a pointer that has to be
resolved at rtld time, which means it can be in .data.rel.ro but not
.rodata like you'd hope. Fix this with the usual string table trick.

If each format channel has the same base type (such unorm), then that
is the format's "uniform channel type".
Calculating the field at buildtime is probably better than looping over
all channels at runtime each time we wish to query it.

Alpha-only formats are just linear. There's no need to specially
deliminate them as being in their own colorspace.

This makes it much easier to edit the template and doesn't really dirty
the python all that much.

This pulls isl and genxml into a single make file so that they can properly
build in parallel. This isn't terribly important now as genxml just
generates sources which happens serially first anyway but it will be more
important as we add more stuff to src/intel.

A while ago we got rid of the bits-per-block because we thought we didn't
need it. We're about to introduce some very useful 1 and 2-bit formats so
we really should be able to handle them again.

This replaces the current bash generator with a python based generator
using mako. It's quite fast and works with both python 2.7 and python
3.5, and should work with 3.3+ and maybe even 3.2.
It produces an almost identical file except for a minor layout changes,
and the addition of a "generated file, do not edit" warning.
