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

When running 'make dist', include the correct chroot-*.c file.

When --enable-gotd is present, and gotd empty path or gitwrapper's git libexec path is set, print those out with the other information at the end of the configure script. "N/A" is set where no value is present. Helpful for debugging.

There's no point installing gitwrapper outside of enabling gotd, as this is only used by gotd.

Document the installation and packaging of gitwrapper for -portable

Rather than hard-code assumptions into gitwrapper and gotd binaries, allow for some values to be overriden at compile time. This should help portability.

Reads (git clone) are working but writes (git push) run into an error

Define a standard path to where git stores its libexec helpers. This is always going to be hit-and-miss hard-coded like this, but will suffice for now. Tested on ubuntu 22.04

This is needed for gitwrapper which will fail if its program name cannot be detected properly.

Bring gotd and gitwrapper closer to how libraries are detected.

Include listen.c; make it portable.

This builds gotctl, for the moment via --enable-gotd

When building gotd, also build gotsh.

This enables gotd -- for now, this is opt-in at compile-time, via: ./configure --enable-gotd
