Each protocol line starts with a command, which is followed by the
command's parameters (a fixed number per command), each separated by a
single space. The last parameter may contain spaces. Parameters may be
empty, but the separating spaces are still required in that case.

## TODO
* Communicate when the network connection may have changed, so long-running
remotes can reconnect.
* uuid discovery during initremote.
* When storing encrypted files stream the file up/down the pipe, rather
than using a temp file. Will probably involve less space and disk IO,
and makes the progress display better, since the encryption can happen
concurrently with the transfer. Also, no need to use PROGRESS in this
scenario, since git-annex can see how much data it has sent/received from
the remote. However, \n and probably \0 need to be escaped somehow in the
file data, which adds complication.
* uuid discovery during INITREMOTE.
* uuid verification during PREPARE (so, for example, it can check if a
removable drive repo has the expected uuid)
* Support for splitting files into chunks.
