Move nv30, nv50 and nvc0 to nouveau.

It is planned to ship openSUSE 13.1 with -shared libs.
nouveau.la, nv30.la, nv50.la and nvc0.la are currently LIBADDs in all nouveau
related targets.
This change makes it possible to easily build one shared libnouveau.so which is
then LIBADDed.
Also dlopen will be faster for one library instead of three and build time on
-jX will be reduced.

Whitespace fixes were requested by 'git am'.

glsl: Add a new glsl_type::sampler_coordinate_components() function.

This computes the number of components necessary to address a sampler
based on its dimensionality.  It will be useful for texturing built-ins.

glsl: Use sampler_coordinate_components instead of passing it by hand.

We used to pass the number of components actually used for the
coordinate (rather than padding, shadow comparitors, and projectors) by
hand, specifying it on every _texture() call.

The new helper function can just compute this, eliminating a lot of
potential mistakes.

trace: Support bigger TGSI shaders.

Trivial.
trace: Several enhancements to dump_state.py

- Handle more calls
- Handle more state
- Try to normalize the output a bit, to eliminate spurious differences
llvmpipe: Remove the special path for TGSI_OPCODE_EXP.

It was wrong for EXP.y, as we clamped the source before computing the
fractional part, and this opcode should be rarely used, so it's not
worth the hassle.
os: First check for __GLIBC__ and then for PIPE_OS_BSD

Fixes FTBFS on kfreebsd-*

Debian GNU/kFreeBSD doesn't provide getprogname() since it uses stdlib.h
from glibc. Instead it provides program_invocation_short_name from glibc.

You can find the same order in src/mesa/drivers/dri/common/xmlconfig.c

mesa: Track the vertex program active at BeginTransformFeedback() time.

The next few patches will use this for API error checking.

All of the drivers appear to CALLOC_STRUCT transform feedback objects,

mesa: Reject ResumeTransformFeedback if the wrong program is bound.

This is actually a pretty important error condition: otherwise, you

a program that generates a completely different set of outputs.

mesa: Disallow relinking if a program is used by an active XFB object.

Paused transform feedback objects may refer to a program other than the
current program.  If any active objects refer to a program, LinkProgram
must reject the request to relink.

The code to detect this is ugly since _mesa_HashWalk is awkward to use,
but unfortunately we can't use hash_table_foreach since there's no way
to get at the underlying struct hash_table (and even then, we'd need to
handle locking somehow).

api-errors test.
