drop: - a tautological s[strlen(s)] == '\0' - a few duplicates checks - a lone if (error) when it's always NULL - an extra NULL check part of a bigger diff that's ok stsp@

fcgi_parse_params parses fastcgi parameters into a list. (This is a leftover from slowcgi where that list is later used to populate the environment of the CGI process.) However, this list is never looked at and its memory never released, so just drop it. Make the matching on fastcgi parameters name strictier by checking also that the length is the one we expect; otherwise we might pick up parameters with the same prefix string (i.e. FOO vs FOO_WITH_SUFFIX) While here turn some bcopy into memcpy and simplify some if-nesting too. Fix the reading from an un-initialized pointer that I introduced in a previous commit. ok stsp@

- don't special case ".got": if it's a work-tree gotwebd will just fail soon enough. Suggested by stsp@ - avoid an strdup. - drop `opened' to make it easier to follow what's going on. ok stsp@

This makes gotwebd use SCRIPT_NAME instead of the DOCUMENT_ROOT fastcgi param to generate the links to the assets and changes some links so every page is consistently linked with a relative URL. It allows to drop the `root "/"' in the location for fastcgi and, as a bonus, also makes possible to run gotwebd on non "/" paths. ok stsp@
