Improve the code in __sync_bool_compare_and_swap_{1,2,4}.
...
- bccs is smaller and faster than bcc(.w) in this case.
- it can be used movql in this case (assembler optimise it though).

Always use sync if mips3 or later or not using O32 ABI. (A little redundant
...
since not using O32 means you are using mips3 or later.)

add a new "fo_mmap" fileops method to allow use of arbitrary uvm_objects for
...
mappings of file objects. move vnode-specific details of mmap()ing a vnode
from uvm_mmap() to the new vnode-specific vn_mmap(). add new uvm_mmap_dev()
and uvm_mmap_anon() convenience functions for mapping character devices
and anonymous memory, and replace all other calls to uvm_mmap() with those.
use the new fileop in drm2 so that libdrm can use mmap() to map things
like on other platforms (instead of the ioctl that we have used so far).

Look for the character to locate before checking for the NUL character
...
As documented in PR port-i386/49208, this fixes strchr(s, '\0'), as used by
the FAT first-stage bootloader on x86 (bootxx_msdos).
strchr(s, '\0') is otherwise equivalent to strlen(string), which would
probably look nicer in the original file, dosfs.c from libsa.
Confirmed working in qemu and on real hardware.
