Modified Files:
        src/sys/kern: exec_subr.c kern_pax.c
        src/sys/sys: pax.h
        src/sys/uvm: uvm_map.c uvm_mmap.c uvm_unix.c

Log Message:
Better implementation of PaX MPROTECT, after looking some more into the
code and not trying to use temporary solutions.

Lots of comments and help from YAMAMOTO Takashi, also thanks to the PaX
author for being quick to recognize that something fishy's going on. :)

Hook up in mmap/vmcmd rather than (ugh!) uvm_map_protect().

Next time I suggest to commit a temporary solution just revoke my
commit bit.
