[Nice] Header name conflict

Hi Tom,

I checked this.. indeed, you could have some conflicts unfortunately..
but I can't include <nice/agent.h> and <nice/*.h> because otherwise,
during development (or when compiling libnice yourself for the first
time, or when upgrading), it won't be able to find all those headers, or
it will take the one installed on the system instead of the ones in the
source directory.
Although the source directory has priority on /usr/include, the problem
is that those files are in agent/*.h or socket/*.h, but you need to
include nice/*.h so it won't find them in the nice/ subdir and it will
take them from /usr/include.

The next version (or current reliable branch in git) will not include
socket.h anyways, so that's fine.. I hope I will find a solution to the
conflicting header names problem without having to break the API or
duplicate my files into the nice directory...

Thank you for reporting,
