Enable possibility to manually pass VM_MAP_32BIT & friends. This is needed
for the PowerPC "JIT1" engine.

Make sure a 32-bit B2/JIT works reasonnably well on AMD64 too. This implies
to force RAMBaseHost < 0x80000000. This is empirically determined to work on
Linux/x86 and Linux/amd64.

- Check for caddr_t. On some systems like Solaris/SPARC, mmap() address
  type (first parameter) is caddr_t instead of void *. Explicitly cast
  address to (caddr_t) type and C++ implicit pointer conversion rules
  will do the rest. aka. caddr_t -> void * is OK unlike the opposite.

- vm_acquire_fixed: Fix memset() and vm_protect() calls so that the address
  is really the one specified instead of always zero.

- video_x.cpp: the_buffer shall always be mapped through vm_alloc() so
  that it can be vm_protect()'ed at will afterwards
- video_x.cpp: let driver_base free() the_buffer_copy and the_host_buffer,
  if necessary
- video_vosf.h: reverted to use malloc() for mainBuffer.dirtyPages and
  mainBuffer.pageInfo
- vm_alloc.cpp: small cleanups
- fixed typos

- Try to map memory contiguously with base addresses returned in increasing
  order. No host memory region used for Mac emulation (ScratchMem, RAM, ROM,
  frame buffer) shall be allocated below the RAM space. Actually, MEMBaseDiff
  should be set to the min(above-mentioned address spaces).
  ==> Temporary fix for 64-bit addressing systems (e.g. Linux/ia64)

Branch: MAIN

- added SIGSEGV support for Linux/Alpha (to be checked), Darwin/PPC
- added uniform virtual memory allocation
  (supports mmap(), vm_allocate(), or fallbacks to malloc()/free())
- cleaned up memory allocation in main_unix.cpp
