This allows using functions that generate CreateProcess and passing the
result to processTranscript', which is more flexible, and also simpler
than the old interface.

That changed the type of error from an IOError to something else, so broke
stuff that was catching IOErrors.
So back to a UserError, but be explicit this time that's what it's
throwing.
Using fail here causes a "user error" exception to be thrown, which implies
the user is at fault in its wording, which is incorrect.
Also audited for other uses of fail in git-annex; the others are in monadic
contexts where fail may not throw an exception, and involve user input, so
kept them as-is.
This is mostly to be able to see how long a command took to run. Also exit
code may be useful.
Unofrtunately, I can't put the command name in there, because it's not
available at this point, and it would be a much larger change to wrap the
ProcessHandle data type to add that. However, it's generally pretty obvious
which process exited from context.
This is certianly a cabal bug for not passing the build options in the
cabal file when building Setup.hs.
And, why oh why did ghc enable this warning by default? So unhappy with
this choice.
Came up with a generic way to filter out progress messages while keeping
errors, for commands that use stderr for both.
--json mode will disable command outputs too.
Some remotes like External need to run store and retrieve actions in Annex,
not IO. In order to do that lift, I had to dive pretty deep into the
utilities, making Utility.Gpg and Utility.Tmp be partly converted to using
MonadIO, and Control.Monad.Catch for exception handling.
There should be no behavior changes in this commit.

For sync, saves 1 ssh connection per remote. For remotedaemon, the same
ssh connection that is already open to run git-annex-shell notifychanges
is reused to pull from the remote.
Only potential problem is that this also enables connection caching
when the assistant syncs with a ssh remote. Including the sync it does
when a network connection has just come up. In that case, cached ssh
connections are likely to be stale, and so using them would hang.
Until I'm sure such problems have been dealt with, this commit needs to
stay on the remotecontrol branch, and not be merged to master.

transferkeys had used special FDs for communication, but that would be
quite annoying to do in Windows.
Instead, use stdin and stdout. But, to avoid commands like rsync stomping
on them and messing up the communications channel, they're duplicated to a
different handle; stdin is replaced with a null handle, and stdout is
replaced with a copy of stderr. This should all work in windows too.
Stopping in progress transfers may work on windows.. if the types unify
anyway. ;) May need some more porting.
This runs git-cat-file in non-batch mode for all files with spaces.
If a directory tree has a lot of them, and is in direct mode, even "git
annex add" when there are few new files will need a *lot* of forks!
The only reason buffering the whole file content to get the sha is not a
memory leak is that git-annex only ever uses this on symlinks.
This needs to be reverted as soon as a fix is available in git!
That's needed in files used to build the configure program.
For the other files, I'm keeping my __WINDOWS__ define, as I find that much easier to type.
I may search and replace it to use the mingw32_HOST_OS thing later.
Nearly everything that's reading from git is operating on a small
amount of output and has been switched to use that. Only pipeNullSplit
stuff continues using the lazy version that yields zombies.
