init: add subsystem rules to ueventd.rc
By default ueventd creates device nodes under /dev based on the ueventd
DEVPATH. Several subsystems have special rules which are hardcoded in
devices.c. Moving forward these special rules should go in ueventd.rc.
Special rules have the syntax:
subsystem <s>
devname (uevent_devname|uevent_devpath)
[dirname <dir>]
Devices matching SUBSYSTEM=<s> will be populated under <dir>. dirname
is optional and defaults to /dev. If dirname is provided, <dir> must
start with "/".
If devname is uevent_devname, ueventd will create the device node as
<dir>/DEVNAME. DEVNAME may include intermediate subdirectories, which
ueventd will automatically create.
If devname is uevent_devpath, ueventd will use the legacy behavior of
computing DEVPATH_BASE=basepath(DEVPATH), and creating the device node
as <dir>/DEVPATH_BASE.
The new parsing code is based on init_parser.c, with small tweaks to
handle commands which don't fall under a section header.
