proc: Allow to make proc_rwmem() operate on a consistent address space

Provide proc_vmspace_ref() to safely obtain the reference to the target
process vmspace, optionally
- requiring that the target cannot execve(2) and thus cannot change its
  vmspace until vmspace in unreferenced
- requiring the check of permissions of the caller after the vmspace
  reference is obtained, since the process lock might have been dropped
  in the process.

execve_block(): a mechanism for mutual exclusion with execve() on the process

A consumer of execve_block(9) is synchorized with the execution of
execve(2) family of syscalls, ensuring that execve_block region is
mutually exclusive with the execve processing. Either execve_block() or
execve() would sleep until other finishes.
