Proper order of eventloop initialization.

For some reason, eventloop watcher structures initialization was
postponed even though there was no reason to do so, as these watchers
only depend on the eventloop itself.
Proper build dependency detection and linkage.

URLFetch should only search for it's dependencies when the plugin is
enabled. Dealer should use detected include and library directories.
CGroups and Blastbeat plugins were missing some of their link libraries.
Release 0.10.2.

Mostly bugfixes and minor improvements. Consult debian/changelog for
release details.
Stub for c++ was added. It now allows us to use the service from c++ code.
CMake fixed, not only binaries but headers are installed too for 'install' target.
Headers and source files went to include and src directories.
Interface of get function changed. It now returns tuple and accepts one more frequently used parameter cookies.
Merge pull request #17 from cocaine/feature-urlfetcher-improved-interface

Stub for c++ was added, interface changes.
Release 0.10.3.

URLFetch service has been rewritten, so now it's usable. Cocaine ABI
version is now added to all plugins via SOVERSION parameter. For more
information, consult debian/changelog.
Leave ABI versions only in package names.

CMake doesn't want to generate shared libraries with SOVERSIONs in them
with names which don't include the version number, so drop it until the
Cocaine Core will be able to handle such plugin names.
Merge branch 'master' into ipvs
Drop network stuff which was moved to Core.

All the network code has been moved to the Core's locator service, it
seems to be the most reasonable place to do service discovery.
