When doing ion / drm detection use access is a better idea. For open
will introduce some unnecessary kernel operation. And access is more
flexible to use library on different stage of boot up.

One thread May have multiple lock/wait/signal source:
Input : signal source from input.
Output : signal source from output.
Control: signal source from async control operation.
Then the main working loop may stop on these lock/wait/signal points.

When mpp_mem debug is enabled there is limit for recording mpp_mem
usage. But there is NO obvious log when this limit is reached.
This case will easily happen on multi-instance decoding in one process.

When in multi-codecs cases, the check_sysfs_iommu function reenters
with high probability, so some codec instances may fail to obtain
the correct memory type.
The root cause is scandir call in find_dir_in_path function. For
efficiency consideration it is better to lock ion_heap_id value.

As we found that simple ion / drm device detectioin can not cover all the
case. For example on some 3368 platform kernel provide both ion and drm
device. We have better to use allocator chosen in dts.
But later kernel patch from Randy will bring unified dma-fd translation in
kernel then this detection will be removed.

Due to complexity of different kernel and usespace combination
we have to detect drm and ion allocator on runtime. The HAVE_DRM

The imported buffer may be released from its origin allocator,
I would suggest to use the new file descriptor from new ion
handle.
The ion only has map_user() to export buffer to userspace,
There is no unmap_user() because the mapping is represented as
a file descriptor in user space. The closing of that file
descriptor will cause the memory to be unmapped from
the calling process.

The "[drm]: fix runtime error for 32bit library" is hack way,
it won't work at GNU Linux platform. Also you need to check
_FILE_OFFSET_BITS and _LARGEFILE64_SOURCE before use the
mmap64().
For the normal mmap() with glibc, we only request to
check offset is aligned with page size but not the lenght.
But that doesn't apply for the memory from the drm device,
also the android use a different rule.
I decide not to map all the buffer to cpu at beginning
since most of them won't be access by the cpu.
