Autotools is already smart enough to pick the *.pc.in files but it

Will be used to consolidate the required sources lists as well as the
install-able headers. This is turn will help us to avoid the
duplication with the upcoming Android build support.
v2: Rename the headers variable to *_H_FILES.
v3: Rebase on top of symbol visibility patches.

This hides all the abi16_* functions and the nouveau_debug variable,
they should have been private to begin with.

I cannot make nouveau_bo_wrap thread-safe (by design), but it seems to be used to convert
drm fb's to nouveau_bo's and to get a notify handle from fifo->notify in nv30_screen.c

Currently single pushbuffer can take up to 80% of VRAM and 80% of GART.
As this value seems to be arbitrary (and user may need to set it differently)
this patch adds support for 2 environment variables:
NOUVEAU_LIBDRM_VRAM_LIMIT_PERCENT (default 80)
NOUVEAU_LIBDRM_GART_LIMIT_PERCENT (default 80)
which will let users override pushbuffer VRAM/GART limits.

Under certain circumstances it's possible for libdrm to decide to move
a GART|VRAM pushbuf to be VRAM-only. This causes the kernel to reject
the command submission on GF8 and up, due to a stricter policy where
buffers are only allowed to move to memory types that were specified
at creation time.
The simplest fix for this is to force the creation-time memory type for
the lifetime of the push buffer.

Valgrind can't understand some of the fields passed to ioctls are overwritten
by kernel, so we need to initialize them. Almost all of our ioctl wrappers
already do it and the cost of remaining 3 is very small.

Redesigned primarily to allow us to better take advantage of BO's having
fixed GPU virtual addresses on GeForce 8 and up, and to reduce the overhead
of handling relocations on earlier chipsets.

nouveau_bo_unmap called the CPU_FINI IOCTL even if it was a NOSYNC
mapping. It caused no harmful effects (actually CPU_FINI is a no-op on
recent enough kernels) besides the precious CPU cycles being wasted.

The motivation behind this is that by shipping it here, it's essentially
an API which causes issues while bisecting across changes to the header
files.
- Currently reloc'ing a user bo to gart will first cause an allocation in vram,
which is then written to by cpu, then the bo gets moved to gart.

This commit encompasses the changes necessary to run on top of the 0.0.16
nouveau interface, additional APIs to support the new features of the
interface, as well as code from Luca Barbieri to improve the pushbuf
interface, which just happens to break nouveau's libdrm ABI so was delayed
until now.
API changes as a result of 0.0.16 DRM interface:
1. No more bo_pin()/bo_unpin(), these were only there for UMS and we no
longer support it.
2. Any random nouveau_bo can be submitted to the GPU as a push buffer.
3. Relocations can be applied on any nouveau_bo
This patch changes the pushbuffer ABI to:
1. No longer use/expose nouveau_pushbuffer. Everything is directly
in nouveau_channel. This saves the extra "pushbuf" pointer dereference.
2. Use cur/end pointers instead of tracking the remaining size.
Pushing data now only needs to alter cur and not both cur and remaining.
The goal is to make the *_RING macros faster and make the interface simpler
and cleaner in the process.
The *_RING APIs are unchanged, but those are inlined and the ABI is changed.
Also, anything accessing pushbuf->remaining instead of using AVAIL_RING
will need to be fixed.
