Title: Fix parsing of Content-Type and Content-Length in FastCGI POSTs

FastCGI PARAMS (and CGI environment variables in general) include all
headers prefixed with HTTP_ except for CONTENT_TYPE and
CONTENT_LENGTH. This handles these in FastCGITransport::getHeader()
so that other users of getHeader(), like the POST code, get the
correct values.
