Changes:

Sync with improvements in mongodb80:
commit b44fe228ca :
Removed SSL from OPTIONS. It was inherited from the first versions
of databases/mongodb, long before I became maintainer.
Currently disabling the SSL option does not disable ssl as ssl is
auto-detected and disabling ssl needs explicit --ssl=off which is
not implemented in the port. I never had a request for this in years
so I decided to just remove the option and have ssl enabled always.

commit 5d8274d264 :
Also found some manual pages in the src tree.

commit f2c9ba7c53 :
add pre-configure check if downloaded mozjs version matches
get-sources.sh.
