conky/src/smapi.c
Phil Sutter 9a85812e06 here comes the big header include rewrite
Some statics are now defined by configure.ac.in, conky.h got a lot
smaller, which I see as a positive sign.

This patch should not change any functionality, just change what's
defined where. Some features I did/could not test are probably broken,
also compiling for any other OS surely won't complete now. Though I
think fixing these problems is as easy as including some missing
headers.

I've done compile checks with the following configure options:
./configure --enable-eve --enable-rss --enable-smapi
	--enable-wlan --enable-debug --enable-testing

So what needs to be tested is:
- audacious
- BMPx
- xmms2
- nvidia
