Replaces libpcre with libpcre2
libpcre was removed and libpcre2 10.21 was added instead.
The files of the c++ wrapper library, libpcrecpp, were moved to
their own directory, pcrecpp. As of this patch pcrecpp is broken
due to the missing dependency libpcre. The port will be added in
a subsequent commit to better document the changes made.
