rust-re2: add wrapper for calling Re2 from Rust
This assumes that Re2 is installed following Google's guide. I am not sure
how we want to integrate it in the project, but I think a follow-up patch would
be more appropriate for such work.
As it stands, *not* having Re2 installed results in a compilation error, which
is a problem as it breaks install compatibility. Hence, this is gated behind
a non-default `with-re2` compilation feature.

# A portable replacement for 'seq'

# Usage:
# seq STOP [1, STOP] stepping by 1
# seq START STOP [START, STOP] stepping by 1
# seq START STEP STOP [START, STOP] stepping by STEP
