19ea743456 Introduce security.pax.mprotect.ptrace sysctl which can be used to bypass 
mprotect settings so that debuggers can write to the text segment of traced
processes so that they can insert breakpoints. Turned off by default.
Ok: chuq (for now)

fb59c30429 Use #ifdef _RUMPKERNEL for now to prefer copyout over kcopy in tests.

a1afb93b8e Back out previous. 
It appears to be causing anita install to fail.  Evidently
VM_SPACE_IS_KERNEL_P(vm) is not mutually exclusive with `vm ==

Making this work in rump for tests will require another approach.

fcc20a4ba1 Split uiomove() and high-level copy routines out of the crowded 
kern_subr and into their own cozy home in subr_copy.
