PCRE2 and PCRE binary compatibility.
With this change, dynamic modules using nginx regex interface can be used
regardless of the variant of the PCRE library nginx was compiled with.
If a module is compiled with different PCRE library variant, in case of
ngx_regex_exec() errors it will report wrong function name in error
messages. This is believed to be tolerable, given that fixing this will
require interface changes.
