Fixes 'No newline at end of file' message appearing in unexpected places. Problem noticed by op@

Reduces the indirection in fcgi.c, starts to make the struct template opaque, simplifies the template usage. All with a net negative :-) reads fine to stsp@ (thanks!)

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@

This greatly reduces the number of tp_puts() calls: gotwebd' pages.tmpl goes from 444 to 190. Otherwise, this doesn't produce other observable changes.

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@

When trying to open a worktree from a list of metadata directories (.got, .cvg), error out when a worktree is found but is already locked. Skipping it and proceeding would result in a confusing "no git repository found" error from tog and gotadmin. ok stsp

Fixes a crash regression introduced when fetch/send were made to close the work tree earlier.

This required minor changes to tog.c to teach tog the new test instructions and feed it search terms when driven by the harness. More is needed for these features but this provides some basic coverage for the & and / log keymaps. ok stsp

This avoids having work tree operations blocked while network transfers are in progress. ok op@

Previously these were hidden behind a general "compression failed" error. ok kn
