chs 6d40f9ff57 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).

khorben 00b617c08a 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.
