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.

The empty string used for the not case is replaced by the default
if-else clause and so causes the configure to fail in the absence of
valgrind. Which is not quite what was intended.
Instead use the common idiom of setting a variable depending on whether
the true or false branch is taken and emit the conditional code as a
second step.

In particular, declare the hidden CPU mmaps to valgrind so that it knows

[anholt: Ideally valgrind should just learn about the ioctls, and
removing the clear for the non-valgrindified code feels risky.]

Commit efd6e81e inadvertently broke the build by looking for "i?86" or
"x86_64" in $host_os. The correct variable to check is $host_cpu.
This was preventing libdrm_intel.so from being built.

This fixes a failure in 'make check' found by the tinderbox when trying to
build this code on Linux/ppc. This code is only designed to run on
Intel platforms, so don't even bother building it if we're not in that set.

Fixes problem that libdrm_radeon was disabled in Makefile even when configure
claimed that radeon was enabled.

bo->referenced_in_cs is checked if bo is already in cs. Adding and removing
reference in bo is done with atomic operations to allow parallel access to a
bo from multiple contexts.
cs->id generation code quarentees there is not duplicated ids which limits
number of cs->ids to 32. If there is more cs objects rest will get id 0.
V2:
- Fix configure to check for atomics operations if libdrm_radeon is only selected.
- Make atomic operations private to libdrm.
This optimization decreases cs_write_reloc share of torcs profiling from 4.3%
to 2.6%.
