Fix race condition related to watching DGL games.
It's possible for a dgamelaunch game to end and cause rlgwebd to stop watching
it before rlgwebd has started watching it.

===== RLGWebD ===== RLGWebD is a node.js app that enables playing roguelike games in the browser. It is intended to be compatible with dgamelaunch. Node --- RLGWebD is currently being updated to work with Node v10.x. It requires the 'posix', 'node-pty', and 'websocket' modules. Currently, it expects them to be installed in "/var/local/lib/node_modules". It is not recommended to run npm as root when installing the modules. init --- RLGWebD now includes a systemd unit file, which is the recommended way to run it. See below for more instructions. For other init systems, a shell script is provided. This is not really a proper initscript, but it could form the basis of one. Configuration --- A configuration file is installed at /etc/rlgwebd.conf. It contains a list of options. If the domain_name option and the SSL-related options are set, rlgwebd will use HTTPS instead of insecure HTTP. If you change the chroot location, change it in the first line of the Makefile too. Installation --- RLGWebD expects to be run in a chroot used by dgamelaunch, and it makes some assumptions about the configuration. It expects the dgamelaunch playground to be at /dgldir inside the chroot. It expects the in-progress files to be in /dgldir/inprogress/<gamename>. RLGWebD creates in-progress files in those locations, and dgamelaunch must be patched to prevent it from deleting them. It needs the devpts filesystem mounted inside the chroot. This can be done with a line in /etc/fstab like the following: devpts CHROOT/dev/pts devpts newinstance,ptmxmode=666 0 0 RLGWebD uses two separate programs written in C. sqlickrypt operates on the dgamelaunch user database. dglwatcher monitors the inprogress directories. Run "make" to build both of them. sqlickrypt needs /dev/urandom to exist in the chroot. Run as root: mknod CHROOT/dev/urandom c 1 9 Running "make install" will: Copy the Web assets into the chroot Copy the C programs and the libraries they need into the chroot Install the main RLGWebD script in /usr/local/bin Place the systemd unit file in the proper directory Copy a configuration file into /etc If you don't use systemd, or want to change the installation locations, you will have to edit the Makefile. You will still need to run "systemctl enable rlgwebd" to make the server start on boot, and "systemctl start rlgwebd" to make it start immediately. Starting and stopping RLGWebD --- If you are using systemd, "systemctl start" and "systemctl stop" should work as with any other service. If you are using the initscript, running it with no arguments will start RLGWebD. Stop by running it with 'stop' as an argument. (This requires socat to be installed.) webtty --- "webtty" is a Node app which uses the terminal emulator to run a shell. It includes NO SECURITY WHATSOEVER and should only be used for testing the terminal emulator. Copy index-sh.html to index.html before running it.
