Parse a term and associated properties. This works with parameters of the form 'Karlheinz' or
'Kunigunde<q:medieval, now rare>' or 'non:Óláfr' or 'ru:Фру́нзе<tr:Frúnzɛ><q:rare>' where the modifying properties
are contained in <...> specifications after the term. `term` is the full parameter value including any angle brackets
and colons; `pname` is the name of the parameter that this value comes from, for error purposes; `deflang` is a
language object used in the return value when the language isn't specified (e.g. in the examples 'Karlheinz' and
'Kunigunde<q:medieval, now rare>' above); `allow_explicit_lang` indicates whether the language can be explicitly given
(e.g. in the examples 'non:Óláfr' or 'ru:Фру́нзе<tr:Frúnzɛ><q:rare>' above).

Normally the return value is an object with properties '.term' (a terminfo object that can be passed to full_link() in
[[Module:links]]) and '.q' (a qualifier). However, if `allow_multiple_terms` is given, multiple comma-separated names
can be given in `term`, and the return value is a list of objects of the form described just above.

Link the terms in `terms`, and join them using the conjunction in `conj` (defaulting to "or"). Joining is done using
serialCommaJoin() in [[Module:table]], so that e.g. two terms are joined as "TERM or TERM" while three terms are joined
as "TERM, TERM or TERM" with special CSS spans before the final "or" to allow an "Oxford comma" to appear if configured
appropriately. (However, if `conj` is the special value ", ", joining is done directly using that value.)
If `include_langname` is given, the language of the first term will be prepended to the joined terms. If
`do_language_link` is given and a given term's language is English, the link will be constructed using language_link()
in [[Module:links]]; otherwise, with full_link(). Each term in `terms` is an object as returned by
parse_term_with_annotations(), i.e. it contains fields '.term' (a terminfo structure suitable for passing to full_link()
or language_link()), optional '.q' (a qualifier) and optional '.eq' (a list of objects of the same form as in `terms`).

Gather the parameters for multiple names and link each name using full_link() (for foreign names) or language_link()
(for English names), joining the names using serialCommaJoin() in [[Module:table]] with the conjunction `conj`
(defaulting to "or"). (However, if `conj` is the special value ", ", joining is done directly using that value.)
This can be used, for example, to fetch and join all the masculine equivalent names for a feminine given name. Each
name is specified using parameters beginning with `pname` in `args`, e.g. "m", "m2", "m3", etc. `lang` is a language
object specifying the language of the names (defaulting to English), for use in linking them. If `allow_explicit_lang`
is given, the language of the terms can be specified explicitly by prefixing a term with a language code, e.g.
'sv:Björn' or 'la:[[Nicolaus|Nīcolāī]]'. This function assumes that the parameters have already been parsed by
[[Module:parameters]] and gathered into lists, so that e.g. all "mN" parameters are in a list in args["m"].
