Merge pull request #1777 from mirage/master

+zmq-3.2-2
Add udunits 0.2.0
Summary:
New version of the parsing libraries (needed by facebook software
soon to be released as open source). This version also works
with ocaml 3.12.1

Test plan:
put this package in my ~/testing repo
opam update testing
opam install pfff
=> it works, it installs pfff-xxx libraries
opam remove pfff
=> it works, it uninstalls pfff-xxx libraries
remove .cmt from install-findlib
Updated patches to match dose patches in opam's src_ext
Now handle all constraints in an upgrade request for the internal solver.
Release 20140313 of PPrint.
Updated build instructions, thanks to Jacques-Pascal Deplaix.
Aligned patch number with opam source, include new patches in opam file.
