If USEMMAP is defined, the shared memory segment is created/attached etc.
now by shm_open() and mmap().
This API is hopefully more often available (at least for iOS).
In order to reduce code duplication I have added new files
sharedmem.[ch] which now encapsulate the shared memory method.
This is based on the work of Proteas to support iOS fuzzing (thanks).

Currently this is in an experimental status yet. Please report
whether this variant works on 32 and 64 bit and on the supported platforms.
This branch enables USEMMAP and has been tested on Linux.
There is no auto detection for the mmap API yet.
