PCRE is now at end of life and is no longer actively maintained. Lift the dependency to the next major version, i.e. PCRE2. Implementation notes: - Removed the pcre study option since: "The new API ... was simplified by abolishing the separate "study" optimizing function; in PCRE2, patterns are automatically optimized where possible." - If asprintf() fails the content of the 'strp' variable is undefined. Lets check the return value and return NULL upon error. - Pattern and subject can straightforwardly be cast to PCRE2_SPTR since we only work with 8-bit code units.
