Add basic infrastructure for sort of automated tests
Now that I have the infrastructure, I can forget about
writing the actual tests. That's how it works, right?

+There aren't any proper tests currently, but some infrastructure is in place to support them.
+
+When compiled with TEST=1, ledit accepts commands on standard input to generate fake events.
+Each command ends in newline. If the last argument is text, it may also contain newlines if
+they are escaped with backslash. Single backslashes that are not in front of a newline are
+just taken verbatim, but two backslashes are collapsed into one. Filenames are a special
+case because they are not allowed to contain '/' or '\0'.
+
+The commands to generate events take raw integers instead of symbolic names for keysyms
+and other parameters. These need to be given using the definitions from Xlib.
+
+The commands currently supported are the following:
+
+k <key_state> <keysym> <text>
+
+Generate a keypress event. <key_state> and <keysym> are the modifier state and keysym.
+
+p <button_num> <x> <y>
+
+Generate a mouse button press event.
+
+r <button_num> <x> <y>
+
+Generate a mouse button release event.
+
+m <x> <y>
+
+Generate a mouse motion event.
+
+l <lang>
+
+Switch to keyboard layout <lang>.
+
+s <view_num>
+
+Switch to view <view_num>, if it exists.
+
+w <filename>
+
+Write the contents of the buffer to <filename>.
+
+d <filename>
+
+Dump various information to <filename>. Currently, the cursor position and
+information about the selection is given. See ledit.c for the exact format.
+
+u <filename>
+
+Dump the undo stack to <filename>. See undo.c for the exact format.
+
+TODO: Add more commands, e.g. for dumping the repetition stack.
+
+
+When compiled with TEST=1, ledit supports an additional command-line argument '-t'.
+This disables handling of the regular key press, mouse, and language switch events
+in order to avoid messing with the results.
+
+Note that regular file writing using :w is disabled when compiled with TEST=1
+in order to avoid overwriting anything important if fuzz testing is done.
