got_repo_pack_fds_close will try to close all of the GOT_PACK_NUM_TEMPFILES fds, even the ones that didn't manage to get a value from got_opentempfd(), which would result in a close(0) if we do not initialize to -1 here.

With the narrow scope of bytes_sent_cur it would always be zero, and we would always update progress. Found by llvm's scan-build (Dead store). OK stsp

Compiling -portable on MacOS directly would never have worked, as the environment was only being set when run under CI. Move these checks into configure.ac so that they propagate out to make, etc. Noticed by cjones on IRC.

These shouldn't have been commited, and probably predate when the .gitignore file was updated to filter out .orig files.

Add the header files under gotwebd to EXTRA_DIST so that they're included in the distribution tarball.

Document how to release a new `-portable` version.

Add a section to the README files explaining how -portable is maintained.

Ensure that the remote GH repo is fetched from.
