cmake: more dependency checks

# - Try to find libev
# Once done this will define
# LIBEV_FOUND - System has libev
# LIBEV_INCLUDE_DIRS - The libev include directories
# LIBEV_LIBRARIES - The libraries needed to use libev
cmake: add auto-detection, improve library search Add auto-detection to the most important features (app, hpack, etc.). Move options to a separate file for easier search. Add cmake-based Libevent, jansson and CUnit search. Move pkg-config handling for Libev and jemalloc to their cmake files. Note: duplicates find_package before including CMakeOptions.txt and when checking for features. Maybe that can be cleaned up later...
