The default misc buffer group do not have the flag. We need to seperate
the default misc group with different flag.

The GKI kernel does not allow non-render thread to open /dev/dri/card0
and alloc drm buffer from it. So we need to use /dev/dri/renderD128
instead.

1. Allocator api is determined by buffer type.
2. Allocator ctx is determined by both buffer type and buffer flags.
3. All allocator dma_heap / drm / ion / ext_dma should support different
buffer flags.
4. The buffer flag supports cacheable / 32-bit / contig options.
5. Add flags update flow on allocator create process.
6. Add mpp_dmabuf_has_partial_ops to disable dmabuf partial ops when the
kernel driver has bug.

1. Move mpp_log.h to inc for external user.
2. Add mpp_debug.h for mpp internal logging.
3. Fix some warning.
4. Add log level setup function.
5. Check env log_level value in mpp_get_log_level call.
NOTE:
1. mpp internal module should use mpp_debug.h and mpp external user
should use mpp_log.h
2. Use mpp_get_log_level to update mpp_log_level when the env changed.

When /dev/mpp_service is opened and be forked to another thread the
leaked fd will increase file refcnt in kernel.
Then the codec kernel session will be leaked on mpp_destroy.

There is a bug when using single drm allocator device for all buffers:
Sample:
1. external fd a is import to mpp_buffer and get handle B / fd b.
2. external fd a is import to mpp_buffer again and get handle B / fd c.
NOTE: The handle is the same in mpp for drm allocator is the same
and the handle ref_count is not increased.
4. release fd b and handle B. (NOTE: The handle B is released in kernel)
5. mmap fd c by handle B. (Crash on getting handle B in kernel)
So we should reacquire handle for fd c when it need mmap or free.

Each of the different alloctor has different alloctor modes,
such as allocating physical continuous memory, secure memory,
etc.

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.

2. Release the drm buffer when the life of the buffer is ended.

1. Use allocator std to replace default normal allocator on all OS.
2. Use wrapper to simplify mpp_allocator.

1. When run the 32bit library without mmap64 it will fail due to lack of mmap64
symbol. So we do a runtime detection.
2. Fix runtime error of missing getpagesize. Use sysconf(_SC_PAGESIZE) instead.
