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.
