Bahadir Balban 2bd26ce684 Added mmap support for MAP_SHARED + MAP_ANONYMOUS ...

mmap() with MAP_ANON | MAP_SHARED is used for creating shared
memory mappings that can be shared among a process and its descendants
(think fork())

Currently shmget/at creates shared virtual files on the fly and calls
do_mmap to create anonymous shared mappings. Now sys_mmap uses this
interface to create virtual files on the fly and call do_mmap on those
files.

In the future a common shared virtual file creation method should be
added and commonly used by both interfaces.
