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.

1. The wrong size information;
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.

1. enable drm allocator in android
2. modify size calculating when alloc
Todo: wait for new interface of kernel to decide
use whether drm or ion as allocator
