We don't do any santiy checking at the point of crating the mmap(), that
is deferred until the pointer is actually dereferenced (as the state of
the object may well change between mmap and pagefault).

Rename the current gem_mmap__{cpu,gtt,wc}() functions into
__gem_mmap__{cpu,gtt,wc}(), and add back wrappers with the original name
that assert that the pointer is valid. Most callers will expect a valid
pointer and shouldn't have to bother with failures.
To avoid changing anything (yet), sed 's/gem_mmap__/__gem_mmap__/g'
over the entire codebase.

gem_mmap__{cpu,gtt,wc} never return MAP_FAILED, it gets converted to
NULL internally. So don't go asserting that the returned value is
not MAP_FAILED.
Done with coccinelle:
@@
type T;
identifier I;
@@
(
I = gem_mmap__gtt(...);
|
I = gem_mmap__cpu(...);
|
I = gem_mmap__wc(...);
)
...
(
- igt_assert(I != MAP_FAILED);
+ igt_assert(I);
|
- igt_assert(I && I != MAP_FAILED);
+ igt_assert(I);
|
- igt_assert(I != (T *) MAP_FAILED);
+ igt_assert(I);
|
- igt_assert(I != NULL);
+ igt_assert(I);
)

Get rid of the gem_mmap() alias of gem_mmap__gtt(). I don't see any
point in having it.

Add a header that includes all the headers for the library. This allows
reorganisation of the library without affecting programs using it and
also simplifies the headers that need to be included to use the library.

The command parser's batch_len optimization causes the parser to
reject this batch as not having an MI_BATCH_BUFFER_END because
the length was not set correctly.
