Generally modernize the language.

Refer to TLS instead of SSL/TLS, and try to have more consistent
usage of commas and that/which.

Reword some descriptions to avoid implying that a list of potential
reasons for behavior is an exhaustive list.

Clarify how get_session_cb() is only called on servers (i.e., in general,
and that it's given the session ID proposed by the client).

Clarify the semantics of the get_cb()'s "copy" argument.
The behavior seems to have changed in commit
8876bc05, though the behavior prior
to that commit was not to leave the reference-count unchanged if
*copy was not written to -- instead, libssl seemed to assume that the
callback already had incremented the reference count.

CAkeyform may be set to PEM, DER or ENGINE, but the current options
are not using the proper optionformat 'E' (OPT_FMT_PDE) for this.

Set the valtype for CAkeyform to 'E' and use OPT_FMT_PDE when extracting
the option value.

This amends bf4006a6 ("Fix regression on x509 keyform argument") which
did the same thing for keyform and changed the manpage synopsis entries
for both keyform and CAkeyform but did not change the option section.
Hence, change the option section.

If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.

Handle this by checking for errors when closing STDOUT (which is a pipe
to the xlate driver).
