deprecated functions and fragile pattern-matching warnings

[andyli]

There are a bunch of warnings, mostly about usages of deprecated functions and fragile pattern-matchings. Would be nice to have them fixed.

[UnixJunkie]

the problem with deprecated things is that obuild is supposed to compile with even very old versions of ocaml.
I guess that for unused variables, a PR would be easily accepted.
