Subject: [PATCH] libs/sys: read model name from /tmp/sysinfo/model if present

Signed-off-by: Gabor Juhos <juhosg@openwrt.org>

Instead of coding the display logic into the graph models, simply annotate
graph models with .detail = true/false and let the renderer decide which
to pick when.

	- move own headers to include/iwinfo/ and shipped ones to include/iwinfo/api/
	- split into libiwinfo and libiwinfo-lua which contains only the binding
	- provide a public api for libiwinfo
	- install development headers and shared objects

2) Added license and attribution for sounds
3) Added linking sounds into the asterisk sounds directory.
