Gets the display text from a wikilink like [[A|B]] or [[B]] gives B
The str:gsub() returns either A|B froma [[A|B]] or B from [[B]] or B from B (no wikilink markup).
In l(), l:gsub() removes the link and pipe (if they exist); the second :gsub() trims white space from the label
if str was wrapped in wikilink markup. Presumably, this is because without wikimarkup in str, there is no match
in the initial gsub, the replacement function l() doesn't get called.

Determines if str is a wikilink, extracts, and returns the the wikilink type, link text, and display text parts.
If str is a complex wikilink ([[L|D]]):
returns wl_type 2 and D and L from [[L|D]];
if str is a simple wikilink ([[D]])
returns wl_type 1 and D from [[D]] and L as empty string;
if not a wikilink:
returns wl_type 0, str as D, and L as empty string.
trims leading and trailing white space and pipes from L and D ([[L|]] and [[|D]] are accepted by MediaWiki and
treated like [[D]]; while [[|D|]] is not accepted by MediaWiki, here, we accept it and return D without the pipes).
