Teach upload-pack to log the received need lines to an fd
To facilitate testing and verification of the requests sent by
git-fetch to the remote side we permit logging the received packet
lines to the file descriptor specified in GIT_DEBUG_SEND_PACK has
been set. Special start and end lines are included to indicate
the start and end of each connection.
$ GIT_DEBUG_SEND_PACK=3 git fetch 3>UPLOAD_LOG
$ cat UPLOAD_LOG

>From the above trace the first connection opened by git-fetch was to
download two refs (with values 8e and dd) and the second connection
was opened to automatically follow an annotated tag (32).
