From: Baptiste Jonglez
It is now possible to search for packages that depend on a given package,
for instance:
/rpc/?v=5&type=search&by=depends&arg=ocaml
It is similarly possible to match on "makedepends", "checkdepends" and
"optdepends".

v2:
- use a subquery instead of a conditional JOIN, to simplify the code
- avoid hard-coding the new list of allowed fields deep inside the code
