+* Get list of spool files *
+*************************************************/
+
+/* Scan the spool directory and return a list of the relevant file names
+therein. Single-character sub-directories are handled as follows:
+
+ If the first argument is > 0, a sub-directory is scanned; the letter is
+ taken from the nth entry in subdirs.
+
+ If the first argument is 0, sub-directories are not scanned. However, a
+ list of them is returned.
+
+ If the first argument is < 0, sub-directories are scanned for messages,
+ and a single, unified list is created. The returned data blocks contain the
+ identifying character of the subdirectory, if any. The subdirs vector is
+ still required as an argument.
+
+If the randomize argument is TRUE, messages are returned in "randomized" order.
+Actually, the order is anything but random, but the algorithm is cheap, and the
+point is simply to ensure that the same order doesn't occur every time, in case
+a particular message is causing a remote MTA to barf - we would like to try
+other messages to that MTA first.
+
+If the randomize argument is FALSE, sort the list according to the file name.
+This should give the order in which the messages arrived. It is normally used
+only for presentation to humans, in which case the (possibly expensive) sort
+that it does is not part of the normal operational code. However, if
+queue_run_in_order is set, sorting has to take place for queue runs as well.
+When randomize is FALSE, the first argument is normally -1, so all messages are
+included.
+
+Arguments:
+ subdiroffset sub-directory character offset, or 0 or -1 (see above)
+ subdirs vector to store list of subdirchars
+ subcount pointer to int in which to store count of subdirs
+ randomize TRUE if the order of the list is to be unpredictable
+ pcount If not NULL, fill in with count of files and do not return list
