In linux-user QEMU that runs for a target with TARGET_ABI_BITS bigger than L1_MAP_ADDR_SPACE_BITS an assertion in page_set_flags fires when mmap, munmap, mprotect, mremap or shmat is called for an address outside the guest address space. mmap and mprotect should return ENOMEM in such case. Change definition of GUEST_ADDR_MAX to always be the last valid guest address. Account for this change in open_self_maps. Add macro guest_addr_valid that verifies if the guest address is valid. Add function guest_range_valid that verifies if address range is within guest address space and does not wrap around. Use that macro in mmap/munmap/mprotect/mremap/shmat for error checking.
