strerror: drop strerror_r dependency
Since the errno module is responsible for introducing replacement
errno values, it should also be responsible for translating those
new values into strings. And by moving the replacements into a
file managed by the errno, we can then break the dependency between
strerror and strerror_r, so that strerror no longer drags in
multi-threading modules required by strerror_r.

perror: work around FreeBSD bug
POSIX requires that 'errno = 0; perror ("")' print the same message

strerror_r has to be replaced, because the strerror_r replacement is

around bugs in the handling of any particular errnum value. Recall
