tests: proof test-stdio.py against buffer fill-up
With the previous code, it could in theory happen that the pipe / PTY buffer of
the child stdout / stderr fills up and the process never finishes.
To prevent that, we read all of the stream before waiting for the end of the
process. To ensure that the stream reaches EOF when the child finishes, we must
close the parent "copy" of the child stdout / stderr.

tests: stablize test-serve.t on Windows
I forget the reason that the subprocess on Windows doesn't print this, but all
other instances of this are similarly conditionalized, so I didn't think too
hard about it.
Also, the server needs to be killed so it doesn't prevent the next run from
working, especially since the port isn't randomized.

commitctx: document the manifest writing function
Same spirit as for `_filecommit` lets document the input and output before
making any change or improvement.
This is part of a larger refactoring/cleanup of the commitctx code to clarify
and augment the logic gathering metadata useful for copy tracing. The current
code is a tad too long and entangled to make such update easy. We start with
easy and small cleanup.

commitctx: reorder some conditional for efficiency in _filecommit
Checking if a dict is empty will be faster than comparing text. I don't expect
it to be a huge performance win, but still a good (but gratuitous) cleanup to
do while we are at it.

clonebundles: optional memory-requirement attribution
The new REQUIREDRAM option allows a client to skip bundles it isn't
expected to handle well, e.g. without swapping. This allows a fallback
path to be provided e.g. using zstd level 10 instead of 22.

documentation: add some internals documentation about bid merge
This is an important algorithm that was only documented on the wiki so far.
Some update to the algorithm (and associated doc) is to expected in the future
since the bid merge algorithm is bug-ridden when it comes to file deletion comes
to play.

cmdserver: document message-encodings and channel output options
While writing the previous patch, I noticed these options are undocumented.
In my testing, a separate status/error message channel works well in GUI
frontend as we no longer have to sort out data and message from mixed outputs.
So let's mark it as not experimental.

cmdserver: add option to not exit from message loop on SIGINT
Sending SIGINT to server is the only way to interrupt a command running in
command-server process. SIGINT will be caught at dispatch.dispatch() if
we're lucky. Otherwise it will terminate the serer process. This is
fundamentally unreliable as signals are delivered asynchronously.
"cmdserver.shutdown-on-interrupt=False" mitigate the issue by making the
server basically block SIGINT.
