git -c was already propagated via environment, but need this for
consistency.
Also, notice it does not use gitAnnexChildProcess to run the
transferrer. So nothing is done about avoid it taking the
pid lock. It's possible that the caller is already doing something that
took the pid lock, and if so, the transferrer will certianly fail,
since it needs to take the pid lock too. This may prevent combining
annex.stalldetection with annex.pidlock, but I have not verified it's
really a problem. If it was, it seems git-annex would have to take
the pid lock when starting a transferrer, and hold it until shutdown,
or would need to take pid lock when starting to use a transferrer,
and hold it until done with a transfer and then drop it. The latter
would require starting the transferrer with pid locking disabled for the
child process, so assumes that the transferrer does not do anyting that
needs locking when not running a transfer.
* Guard against running in a repo where annex.uuid is set but
annex.version is set, or vice-versa.
* Avoid autoinit when a repo does not have annex.version or annex.uuid
set, but has a git-annex objects directory, suggesting it was used
by git-annex before.
I need to think about this some more, not clear if it's a todo
item specific to stalldetection at all. Remotes with this behavior
also show no progress when run with -J. And some other remotes don't
update any progress meters at all, eg adb is that way and so are hook
remotes and of course external remotes don't have to send progress info.
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.

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.
This is to avoid breakage when upgrading or downgrading git-annex with a
process running that uses the interface. It's better to keep the
compatability code for a few years than worry about such breakage.

New config annex.stalldetection, remote.name.annex-stalldetection, which
can be used to deal with remotes that stall during transfers, or are
sometimes too slow to want to use.

That seems to be the last thing needed for message serialization.
Although it's only used in the assistant currently, so hard to tell if I
forgot something.
At this point, it should be possible to start using transferkeys
when performing transfers, which will allow killing a transferkeys
process if a transfer times out or stalls. But that's for another day.

Added annex.adjustedbranchrefresh git config to update adjusted branches
set up by git-annex adjust --unlock-present/--hide-missing.
Note, in a few cases, I was not able to make the adjusted branch
be updated in calls to moveAnnex, because information about what
file corresponds to a key is not available. They are:
* If two files point to one file, then eg, `git annex get foo` will
update the branch to unlock foo, but will not unlock bar, because it
does not know about it. Might be fixable by making `git annex get
bar` do something besides skipping bar?
* git-annex-shell recvkey likewise (so sends over ssh from old versions
of git-annex)
* git-annex setkey
* git-annex transferkey if the user does not use --file
* git-annex multicast sends keys with no associated file info
Doing a single full refresh at the end, after any incremental refresh,
will deal with those edge cases.
Note that, the way the SeekInput parser is written to support batch mode,
it's actually possible to do git-annex examinekey
"SHA1--foo foo.tar.gz" --migrate-to-backend=SHA1E
While that might be kind of useful to support multiple migrations not using
batch mode, I have not documented it. It would be better to take pairs of
key and file in that case.
