Currently we dynamically allocate 16 pointers and reallocate more as
needed.
Instead, allocate the maximum number (256) on stack - the number is
small enough and is unlikely to change in the foreseeable future.
This allows us to simplify the error handling and even shed a few bytes
off the final binary.
v2:
- add a define & description behind the magic 256
- report error to strerr and skip when over 256 device nodes

Currently we match the opened drmDevice fd with each drmDevice we

Move that after all the devices are processed and folded, via the

In mesa/gallium, a pipe_fence can outlive the pipe_context it was
created from. But to wait on the fence we need to know the submit-
queue (ie. the fd_pipe).
The most straightforward way to fix this is to add reference counting
to the fd_pipe and let the fence hold a reference to the pipe (rather
than hanging on to the context, which might have been destroyed before
the fence).

In trying to integrate the new gralloc_handle.h with the
drm_hwcomposer, I started seeing the following compilation
errors:
In file included from external/drm_hwcomposer/platformdrmgeneric.cpp:28:
external/libdrm/android/gralloc_handle.h:108:9: error: cannot initialize return object of type 'native_handle_t *' (aka 'native_handle *') with an lvalue of type 'struct gralloc_handle_t *'

^~~~~~
1 error generated.
This seems to be due to the gralloc_handle_create() definition
needs to return a native_handle_t * type, rather then a
gralloc_handle_t *, which is what the code actually returns.
After talking w/ Rob Herring, having the code return the
native handle should be the proper fix, so that is what
this patch changes.

This patch makes the code not rely anymore on libpciaccess when compiled
for Android to eliminate ioperm() and iopl() syscalls required by that

checked be grepping relevant code in drm_gralloc and Mesa.

When building AOSP after updating libdrm project to the
freedesktop/master branch, I've seen the following build errors:
external/libdrm/intel/Android.mk: error: libdrm_intel
(SHARED_LIBRARIES android-arm64) missing libpciaccess
(SHARED_LIBRARIES android-arm64) You can set
ALLOW_MISSING_DEPENDENCIES=true in your environment if this is
intentional, but that may defer real problems until later in the
build.
Using ALLOW_MISSING_DEPENDENCIES=true when building allows
things to function properly, but is not ideal.
So basically, while I'm not including the libdrm_intel package
into the build, just the fact that the Android.mk file references
libpciaccess which isn't a repo included in AOSP causes the build
failure.
So it seems we need some sort of conditional filter in the
Android.mk to skip over it if we're not building for intel.

Meson's compiler.has_header is completely useless, it only checks that a
header exists, not whether it's usable. This creates problems if a
header contains a conditional #error declaration, like so:
> #if __x86_64__
> # error "Doesn't work with x86_64!"
> #endif
Compiler.has_header will return true in this case, even when compiling
for x86_64. This is useless.
Instead, we'll do a compile check so that any #error declarations will
be treated as errors, and compilation will work.
Fixes compilation on x32 architecture.
