We will need to disable the repair mode before connect()
to restore syn-sent sockets. And even now connect() looks
like a part of internal logic of libsoccr.

These addresses will be used to restore half-closed sockets,
we will need to send a fake fin packet for that.
And in the next patch connect() will be moved into soccr.

loge() will start a message with "Error:" and
logd() will start a message with "Debug:".
logerr() will add strerror(errno) to the end of messages.

Some of the loge messages where missing a '\n'. For consistency this
adds '\n' to all messages which were missing it.

Made a symlink to CRIU's generated config.h, played with
moving some code to soccr.h header.
Changed types from u32 to uint32_t, otherwise we should
include CRIU's "int.h" in soccr, but I'm lazy to add that.

In TCP repair some stuff should be restored before calling
connect/bind on socker and some -- after it.

As an API for dumping and restoring the data the structure
with __u32-s is used. Getting one (and restoring) also involve
the size of the structure so that both -- caller and library --
can know which "version" of it the other one is using.
As a starting point all the fields that tcp_entry carries are
used.
Also note, that only tcp connection info is handled by the
library. Stuff like addresses and ports, socket options and
other are left for the caller to care for.

The calls put socket into a mode where it can be saved or
restored. Add take one out of this mode.
TODO: In criu we turn repair off (resume the socket) from

fix it.

In order to get messages from libsoccr I propose to
introduce a printing callback that can be set by library
user and that will be called by libsoccr.

For now build the .a library not to produce criu wrappers.
Next version should include the .so library as well.
