add support for ignore by regex

[t-bltg]

I'm trying to generate MPI signatures in JuliaParallel/MPI.jl#644.

It would be convenient to filter output by regex, since output_ignorelist requires listing everything by hand (and this would take more time than writing this PR).

E.g. this works in my generator.toml:

output_ignoreregex = ["^PMPI_", "^QMPI_"]

It would be great if we could add regex support to output_ignorelist instead of introducing a new config entry.

Thanks for poiting to #380.

The problem is that the .toml cannot parse regex string macros:

ERROR: TOML Parser error:
none:5:21 error: unexpected start of value
  output_ignorelist = [r"^PMPI_", r"^QMPI_", r"^MPIX_", r"^PMPIX_", r"^QMPIX_", r"^MPI_T_", r"^MPI_Session_"]
                      ^                                                                                       
Stacktrace:
 [1] parse
   @ ./toml_parser.jl:441 [inlined]

Thus, we cannot distinguish regexes from regular string in output_ignorelist, thus breaking the current behavior if we make all entries in output_ignorelist behave like regexes.

Please advise on the implementation ?

Is it feasible to treat everything as regex string?

I can not come up with an ambitious case.

I guess I can try. Would that imply exclusivelist should become one too ?

EDIT: ignorelist now mapped to a regex, this works for our MPI PR.

Thanks!

Amazing.

Would it be possible to tag a new version so that we can add a valid [compat] entry for Clang.jl in JuliaParallel/MPI.jl#644 ?
