next try to fix --with-perl_modules_path= for unpriviliged user installation

    *) Change in internal API: the HTTP modules initialization was moved
       from the init module phase to the HTTP postconfiguration phase.

    *) Change: now the request body is not read beforehand for the
       ngx_http_perl_module: it's required to start the reading using the
       $r->has_request_body method.

    *) Feature: the ngx_http_perl_module supports the DECLINED return code.

    *) Feature: the ngx_http_dav_module supports the incoming "Date" header
       line for the PUT method.

    *) Feature: the "ssi" directive is available inside the "if" block.

    *) Bugfix: a segmentation fault occurred if there was an "index"
       directive with variables and the first index name was without
       variables; the bug had appeared in 0.1.29.

    *) Feature: the ngx_http_perl_module supports the $r->args and
       $r->unescape methods.

    *) Feature: the method $r->query_string of ngx_http_perl_module was
       canceled.

    *) Bugfix: segmentation fault was occurred if the "none" or "blocked"
       values was specified in the "valid_referers" directive; the bug had
       appeared in 0.3.18.

    *) Feature: the ngx_http_perl_module.

    *) Change: the "valid_referers" directive allows the referreres without
       URI part.
