crtools: preload libraries (v2) Libraries (plugins) is going to be used for dumping and restoring external dependencies (e.g. dbus, systemd journal sockets, charecter devices, etc) A plugin can have the cr_plugin_init() and cr_plugin_fini functions for initialization and deinialization. criu-plugin.h contains all things, which can be used in plugins. v2: rename lib to plugin v3: add a default value for a plugin path.

unix: add ability to set callbacks for external sockets (v5) We don't know a state behind an external socket. It depends on logic of the program, which handles this socket. This patch adds ability to load a library with callbacks for dumping and restoring external sockets. This patch introduces two callbacks cr_plugin_dump_unix_sk and cr_plugin_restore_unix_sk. If a callback can not handle a socket, it must return -ENOTSUP. The main questions, what kind of information should be tranfered in these callbacks. Pls, think a few minutes about that and send me your opinion. v2: Use uflags instread of adding a new field v3: clean up v4: Unsuitable callbacks return -ENOTSUP. v5: set USK_CALLBACK, if a socket was dumped by callback.
