Get a bit fancier with the builtin app specifications, so that we can generate them from apps as well as the config.

# XXX need to fix stack size numbers here so that apps can set them.

# Builtin commands can be generated by the configuration, in which case they
# must refer to commands that already exist, or indirectly generated by applications
# when they are built.
#
# The configuration supplies builtin command information in the BUILTIN_COMMANDS
# variable. Applications make empty files in $(WORK_DIR)/builtin_commands whose
# filename contains the same information.
#
# In each case, the command information consists of four fields separated with a
# period. These fields are the command's name, its thread priority, its stack size
# and the name of the function to call when starting the thread.
