gotwebd: templateify gotweb_render_summary ok jamsek

gotwebd: bubble up got_get_repo_tags This bubbles up the call to got_get_repo_tags from gotweb_render_tags to its caller, gotweb_process_request and gotweb_render_summary. It helps simplifying gotweb_render_summary and making it easier to templateify, but also helps in untangling a bit the code. At this point gotweb_render_tags becomes just a wrapper to gotweb_render_tags_tmpl so switch completely to it. ok jamsek

gotwebd: templateify gotweb_render_branches no functional change intended. Bubble up the allocation of the reflist from gotweb_render_branches to gotweb_render_summary (its only caller) and rewrite it as a template. ok tracey@

backout 169b163113a6db9878c9166aa05fbd30d05eb832 pushed by mistake, wasn't reviewed.

gotwebd: templateify gotweb_render_diff To avoid calling functions from got_operations.c directly from a template (which would hide the error), change got_output_repo_diff into got_open_diff_for_output that returns a file with the diff in it, to be then rendered by the template. got_gotweb_flushfile needs to be exposed then. It also bundles a smaller change: the `label' argument of got_repo_match_object_id is optional and not used, so just pass NULL there.

gotwebd: urlencode also the double quote character URLs are embedded as part of the HTML and, while it seems legal from RFC3986 to leave that character unquoted, we need it quoted to avoid breaking the HTML output. ok tracey@

gotwebd: templateify gotweb_render_tree ok tracey@

gotwebd: render BLOB inline, add BLOBRAW for serving raw blobs binary blobs are automatically redirected to the BLOBRAW page (which is the old BLOB.) ok jamske

change gotweb_render_content_type argument type to const char * it's a string, `const char *' is fine (and what all the callers use anyway.)

gotwebd: use Content-Disposition for RSS; sets the filename Since gotwebd serves the RSS from a path without a file name component, browsers just make up a random string to give the file a name which can be confusing. Furthermore, since it's served as application/rss+xml they try to render the XML (failing.) Use gotweb_render_content_type_file (which sets the Content-Disposition HTTP header) to fix both: the feed is now called <repo-name>.rss and set as attachment (thus saved and not rendered.) Change the function to take an optional filename suffix for the occasion. ok jamsek

gotwebd: tweak gotweb_render_content_type_file parameters type `type' and `file' are strings so use `const char *' for both.

gotwebd: drop redundant NULL check qs is guaranteed to be not NULL reached that point.

gotwebd: remove useless comment should be placed further down, after BLOB and RSS are handled, but the call to `gotweb_render_header' is successfully clear on its own.

gotwebd: add an RSS feed for the tags ok tracey@

gotwebd: templateify gotweb_render_commits ok tracey@

gotwebd: templateify gotweb_render_navs ok tracey@

gotwebd: drop index_page_str and page_str gotwebd uses sprintf to update index_page_str and page_str if they were negative. While this specific usage is safe, let's drop it. Since the index_page_str and page_str fields are never read from, remove them. This saves two allocations per request too. ok tracey@

gotwebd: fix broken navigation in commits page since 8d02314 ok tracey@

gotwebd: start using the template system ok tracey@

gotwebd: simplify bit of gotweb_process_request ok tracey

gotwebd: provide maximum value for the description and cloneurl ok stsp@

gotwebd: rework gotweb_get_repo_{description,cloneurl} - use openat(2) since we've already opened the containing dir - use fstat(2) instead of multiple seeks - don't special case len == 0 ok and improvements by stsp
