pcre is deprecated

[NotFound]

The pcre module is deprecated from core. It will be moved to another repo if someone wants to take care of it, or just removed if not.

This is an early notice, waiting a few days before adding to api.yaml just in case someone has a good reason to keep it.

Have attached file with list of source code files containing pcre|PCRE. We should probably look into the following subset of that list to see why people wanted PCRE in Parrot in the first place:

./docs/book/draft/appd_build_options.pod
./docs/book/draft/chXX_library.pod
./examples/library/ncurses_life.pir
./examples/library/pcre.pir
./runtime/parrot/library/libpcre.pir
./runtime/parrot/library/pcre.pir
./src/nci/extra_thunks.nci
./t/examples/library.t
./t/library/pcre.t
./tools/dev/mk_inno.pl
