Merge pull request #3144 from sagotch/master

Updated toml to 2.1.0 version.
coccinelle doesn't compile with pcre newer than 7.1.1 with ocaml 4.00.0 and
4.01.0, so I am fixing the version of pcre needed by coccinelle to 7.1.1
since not everybody is working with a bleeding edge 4.02.0 ocaml compiler
= 7.1.1 moved to <= 7.1.1 for the pcre dependency, as required by master yallop
