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 buffer management system still have a problem with different
memory type, I have to fake the drm buffer as the ion buffer this
time.

It would make the build system more simple, and the cross
toolchains would do the rest to you.
Toolchains like buildroot default not enable the __gnu_linux__
marco in the pre-processor will surfure from the systsm unknown
problem. You should enable the marco in building toolchains
or have a look on those scripts in build directory.

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

x86_64 is for simulation debug. It is just for working flow test.
