filter out control characters in warning messages
Converted warning and similar to use StringContainingQuotedPath. Most
warnings are static strings, some do refer to filepaths that need to be
quoted, and others don't need quoting.

Note that, since quote filters out control characters of even
UnquotedString, this makes all warnings safe, even when an attacker
sneaks in a control character in some other way.

When json is being output, no quoting is done, since json gets its own
quoting.

This does, as a side effect, make warning messages in json output not
be indented. The indentation is only needed to offset warning messages
underneath the display of the file they apply to, so that's ok.

plumb VerifyConfig into retrieveKeyFile
This fixes the recent reversion that annex.verify is not honored,
because retrieveChunks was passed RemoteVerify baser, but baser
did not have export/import set up.

suggest when user may want annex.stalldetection
When annex.stalldetection is not enabled, and a likely stall is detected,
display a suggestion to enable it.

Note that the progress meter display is not taken down when displaying
the message, so it will display like this:

	0%    8 B                 0 B/s
	  Transfer seems to have stalled. To handle stalling transfers, configure annex.stalldetection
	0%    10 B                0 B/s

Although of course if it's really stalled, it will never update
again after the message. Taking down the progress meter and starting
a new one doesn't seem too necessary given how unusual this is,
also this does help show the state it was at when it stalled.

Use of uninterruptibleCancel here is ok, the thread it's canceling
only does STM transactions and sleeps. The annex thread that gets
forked off is separate to avoid it being canceled, so that it
can be joined back at the end.

A module cycle required moving from dupState the precaching of the
remote list. Doing it at startConcurrency should cover all the cases
where the remote list is used in concurrent actions.

avoid transferrer committing the git-annex branch on shutdown
The parent is will do it when it shuts down, and having both of them
trying to do it at the same time seems like something good to avoid.

propagate signals to the transferrer process group
Done on unix, could not implement it on windows quite.

The signal library gets part of the way needed for windows.
But I had to open https://github.com/pmlodawski/signal/issues/1 because
it lacks raiseSignal.

Also, I don't know what the equivilant of getProcessGroupIDOf is on
windows. And System.Process does not provide a way to send any signal to
a process group except for SIGINT.

make getViaTmpFrom no longer update location log
All callers adjusted to update it themselves.

In Command.ReKey, and Command.SetKey, the cleanup action already did,
so it was updating the log twice before.

This fixes a bug when annex.stalldetection is set, as now
Command.Transferrer can skip updating the location log, and let it be
updated by the calling process.

custom protocol for transferrer
Rather than using Read/Show, which would force me to preserve data types
into the future.

I considered just deriving json and sending that, but I don't much like
deriving json with data types that have named constructors (like Key
does) because again it locks in data type details.

So instead, used SimpleProtocol, with a fairly complex and unreadable
protocol. But it is as efficient as the p2p protocol at least, and as
future proof.

(Writing my own custom json instances would have worked but I thought
of it too late and don't want to do all the work twice. The only real
benefit might be that aeson could be faster.)

Note that, when a new protocol request type is added later, git-annex
trying to use it will cause the git-annex transferrer to display a
protocol error message. That seems ok; it would only happen if a new
git-annex found an old version of itself in PATH or the program
file. So it's unlikely, and all it can do anyway is display an error.
(The error message could perhaps be improved..)
