Remove PAGE_RESERVED
The usermode PAGE_RESERVED code is not required by the current mmapimplementation, and is already broken when guest_base != 0.Unfortunately the bsd emulation still uses the old mmap implementation,so we can't rip it out altogether....

linux-user: Rewrite mmap_find_vma() to work fine on 64-bit hosts with 32-bit targets
qemu's page table can be incomple if /proc/self/maps is unavailable orhost allocating a memory with mmap(), so we can't use it to find freememory area.
New version mmap_find_vma() uses mmap() without MAP_FIXED to find free...
