Almost, but not entirely, and if we want to settle on a single term now is a
good time before it diverges too far.

To be fair, the NSS documentation has more or less not seen updates at all in
years, large parts of the API are completely missing.

The best maintained TLS library documentation today is, I would argue, OpenSSL
and grepping around there (unscientifially) looks a bit different:

SSL: 177 (corrected for not counting the SSL struct)
SSL/TLS (or TLS/SSL): 154
TLS: 252

This patch came about since there was an ask over in the NSS thread to top
using SSL as a term, but if there isn't enough support to warrant the churn
then we should standardize on SSL and just include a paragraph explaining what
we mean by that.
