Refactor to use an alternative method for shared memory.

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).
https://github.com/Proteas/afl-ios/commit/866af8ad1cb230d5d753b546380a4af1e55d6946

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.
