perl.h: Add capability for many-reader ENV mutex locking
There are several places where there could be a problem in the
environment were changed by another thread when a function is executing,
but otherwise if another thread were reading the environment at the same
time, there isn't a problem. This adds mutex for that situation.
Future commits will take advantage of it.

Add GETENV_LOCK
get_env() needs to lock other threads from writing to the environment
while it is executing. It may need to have an exclusive lock if those
threads can clobber its buffer before it gets a chance to save them.
The previous commit has added a Configure probe which tells us if that
is the case. This commit uses it to select which type of mutex to use.
