Copy regex unnamed captures to cloned subrequests. Previously, unnamed regex captures matched in the parent request, were not available in a cloned subrequest. Now 3 fields related to unnamed captures are copied to a cloned subrequest: r->ncaptures, r->captures and r->captures_data. Since r->captures cannot be changed by either request after creating a clone, a new flag r->realloc_captures is introduced to force reallocation of r->captures. The issue was reported as a proxy_cache_background_update misbehavior in http://mailman.nginx.org/pipermail/nginx/2018-December/057251.html.
