sched/addrenv.c: Implement re-entrancy for addrenv_select()

Store the old environment in a local context so another temporary address
environment can be selected. This can happen especially when a process
is being loaded (the new process's mappings are temporarily instantiated)
and and interrupt occurs.

sched/addrenv: Miscellaneous clean-up and fixes

- Remove the temporary "saved" variable when temporarily changing MMU
  mappings to access another process's memory. The fact that it has an
  address environment is enough to make the choice
- Restore nxflat_addrenv_restore-macro. It was accidentally lost when
  the address environment handling was re-factored.

This creates a generic and safe way to read a process argument vector
as string from any context.
