e1f663b543 lib: Add gem_userptr and __gem_userptr helpers
This patch moves userptr definitions and helpers implementation that were
locally in gem_userptr_benchmark and gem_userptr_blits to the library, so other
tests can make use of them as well. There's no functional changes.

v2: added __ function to differentiate when errors want to be handled back in
the caller; bring gem_userptr_sync back to gem_userptr_blits; added gtkdoc.
v8: remove local_i915_gem_userptr from gem_concurrent_all.c to use the global
helpers instead.

85ee6e7b36 gem_userptr_benchmark: Test overlapping bo mmu notifier performance impact
Current userptr kernel implementation downgrades tracking VMA ranges (real
userspace ones) to an inefficient linear walk for any process which has
instantiated overlapping userptr objects.

This adds a test which shows the performance cliff on, most visibly, generic
userspace mmap(2) and munmap(2) operations between unsync, non-overlapping
and overlapping userptr objects.

1b55886c4b test/gem_userptr_*: Fix compile fail
Also shut up warnings. Those revealed incorrect usage of local
variables in conjunction with igt_fixture/igt_subtest. Since those use
longjmps we need to move the out of the stackframe those magic blocks
are declared in.

d3057d7a1e tests/gem_userptr_benchmark: Benchmarking userptr surfaces and impact
This adds a small benchmark for the new userptr functionality.

Apart from basic surface creation and destruction, also tested is the
impact of having userptr surfaces in the process address space. Reason
for that is the impact of MMU notifiers on common address space
operations like munmap() which is per process.

v2:
  * Moved to benchmarks.
  * Added pointer read/write tests.
  * Changed output to say iterations per second instead of
    operations per second.
  * Multiply result by batch size for multi-create* tests
    for a more comparable number with create-destroy test.

v3:
  * Use ALIGN macro.
  * Catchup with big lib/ reorganization.
  * Removed unused code and one global variable.
  * Fixed up some warnings.

v4:
  * Fixed feature test, does not matter here but makes it
    consistent with gem_userptr_blits and clearer.
