gotwebd: try to improve copy-paste from BLOB pages This moves the space inside the line anchor and makes it non-selectable, so that when copy-pasting, only the content of line lines is actually copied. At the moment, this seems to behave slightly incorrectly in firefox which inserts a double line break due to the presence of unselectable elements inside the selection. Hopefully it will be fixed, chromium behaves fine. It also still works decently on text-browsers. ok stsp@

gotwebd: remove PAGE handling The page querystring parameter is long gone and currently unused. It was replaced mith the "more" buttons in all the views, except INDEX that uses `index_page'. ok jamsek

gotwebd: add foldable commit briefs with input/ok from jamsek, tracey and Kyle Ackerman, thanks!

gotwebd: use 'more' for the tag listing too prodded by stsp and jamsek; ok stsp@

gotwebd: dedup the bulk of the tree listing code

plug a memleak in previous; from op@

show tree and README at the bottom of the summary page ok op@

gotwebd: swap the tags and branch listing in the index page discussed / ok stsp@

gotwebd: render READMEs in the tree view ok tracey@

gotwebd: use breadcumbs in more actions Breadcumbs are useful not only in the TREE and BLOB action, but also in COMMITS/BRIEFS and BLOB. prodded by stsp@

gotwebd: add actions in the diff view too

gotwebd: add patch action to serve diffs in plain text ok tracey@

gotwebd: make blame view work in text browsers While here pad line numbers with spaces instead of zeroes to match the blob view.

gotwebd: add actions to the blame view ok tracey@

gotwebd: add links for actions in the blob page positive feedback from Kyle Ackerman ok/tweak tracey@

gotwebd: introduce .page_header_wrapper to avoid style repetitions while here clean up some *_header id not used / not needed.

gotwebd: adjust blob line number for text browsers

gotwebd: add breadcums to navigate the tree/blob views ok tracey@

gotwebd: get rid of proc.[ch] proc.c really shines when there's a network of different types of processes, potentially with a various number of instances each, that needs to exchange messages. Gotwebd instead has a much simpler design, and using proc.c causes more overhead (/headaches) than it solves. So, this attempts to provide the same functionalities but with a much simpler implementation that fits gotwebd better. ok stsp@

gotwebd: render all the datetimes in a time tag fixes an unused variable that should have been dropped in previous commit too. ok stsp@

gotwebd: inline the only use of TM_RFC822

gotwebd: typo; fix closing of dd tag

gotwebd: don't loose track of the file in commit listing When browsing the history of a file, the more button should generate a link containing the file= parameter, otherwise we switch back to the 'global' history. Spotted by stsp@

gotweb: style improvements First round of polishing, css simplification and responsiveness for gotwebd. The new HTML is now actually usable on text-only browsers and the fonts are bigger on smaller screens; close to no changes for "normal" desktop usage. A few regressions were spotted by Lucas on IRC, thanks! No objections from stsp@

bubble up got_repo_commits() now that got_get_repo_commits() doesn't look at `action' we can stop fetching the commits during the rendering and bubble up the call. This yields better error messages and better replies codes on failure.
