Eelco Dolstra d7a92ed4a9 nix-store --serve: Only monitor stdin during builds
Other operations cannot hang indefinitely (except when we're reading
from stdin, in which case we'll notice a client disconnect). But
monitoring works badly during compressed imports, since there the
client can close the connection before we've sent an ack.

Eelco Dolstra 0fae20c362 Use pthread_cancel instead of a signal
Signal handlers are process-wide, so sending SIGINT to the monitor
thread will cause the normal SIGINT handler to run. This sets the
isInterrupted flag, which is not what we want. So use pthread_cancel
instead.

Eelco Dolstra 78224cd871 nix-store --serve: Monitor for client disconnects
This is necessary because build-remote.pl now builds via ‘nix-store
--serve’. So if a build hangs without writing to stdout/stderr, and
the client disconnects, then we need to detect that.

Eelco Dolstra 49fe9592a4 nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects
The thread calls poll() to wait until a HUP (or other error event)
happens on the client connection. If so, it sends SIGINT to the main
thread, which is then cleaned up normally. This is much nicer than
messing around with SIGPOLL.

Eelco Dolstra 049c0eb49c nix-daemon: Add trusted-users and allowed-users options
‘trusted-users’ is a list of users and groups that have elevated
rights, such as the ability to specify binary caches. It defaults to
‘root’. A typical value would be ‘@wheel’ to specify all users in the
wheel group.

‘allowed-users’ is a list of users and groups that are allowed to
connect to the daemon. It defaults to ‘*’. A typical value would be
‘@users’ to specify the ‘users’ group.

Eelco Dolstra 276a40b31f Handle case collisions on case-insensitive systems
When running NixOps under Mac OS X, we need to be able to import store
paths built on Linux into the local Nix store. However, HFS+ is
usually case-insensitive, so if there are directories with file names
that differ only in case, then importing will fail.

The solution is to add a suffix ("~nix~case~hack~<integer>") to
colliding files. For instance, if we have a directory containing
xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to
"xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR,
the suffixes are removed. Thus, importing and exporting via a
case-insensitive Nix store is round-tripping. So when NixOps calls
nix-copy-closure to copy the path to a Linux machine, you get the
original file names back.

Closes #119.

Eelco Dolstra fa13d3f4f3 build-remote.pl: Fix building multiple output derivations
We were importing paths without sorting them topologically, leading to

Eelco Dolstra a5c6347ff0 build-remote.pl: Use ‘nix-store --serve’ on the remote side
This makes things more efficient (we don't need to use an SSH master
connection, and we only start a single remote process) and gets rid of
locking issues (the remote nix-store process will keep inputs and
outputs locked as long as they're needed).

It also makes it more or less secure to connect directly to the root
account on the build machine, using a forced command
(e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix
daemon and is therefore more efficient.

Also, don't call nix-store to import the output paths.
