Jerry Zhang	ecee434fae	adb: Use kernel aio for functionfs. ... This method works around the downsides of ENDPOINT_ALLOC, namely that it is not affected by memory fragmentation and it uses an upstream interface. Also add libasyncio to provide the necessary syscalls to both adb and mtp. Add some small optimizations to file_sync.

Jerry Zhang	55205a565b	adb: Pre allocate kernel memory ... This allows reliable use of larger buffer sizes. Max r/w size is set only when that preallocation is successful so that memory is guaranteed to be available.
