hgweb: add parents to json-log (issue5074)
Entries prepared in webutil.changelistentry() skip showing parents in the
trivial case when there's only one parent and it's the previous revision. This
doesn't work well for the json-log template, which is supposed to just dump raw
data in an easy-to-parse format, so let's provide all parents as another
keyword: allparents.
Using a lambda function here means that the performance of templates that don't
use allparents won't be affected (see 41957e50e109).
