Generate only one large library "libtoxcore".

This library contains all the code for the old libtoxcore, libtoxav,
libtoxdns, and libtoxencryptsave. The build for toxav is still optional,
and disabling it causes libtoxcore to simply not contain those symbols
and the pkg-config file to not include opus and vpx as dependencies.

#
# The main toxcore CMake build file.
#
# This file when processed with cmake produces:
# - A number of small libraries (.a/.so/...) containing independent components
# of toxcore. E.g. the DHT has its own library, and the system/network
# abstractions are in their own library as well. These libraries are not
# installed on `make install`. The toxdns, toxav, and toxencryptsave
# libraries are also not installed.
# - A number of small programs, statically linked if possible.
# - One big library containing all of the toxcore, toxav, toxdns, and
# toxencryptsave code.
