Don't mix various types of sockets in a single
test case, in case of problems it become harder
to fins which kind of socket failed.

The removed test cases will be addressed in
further patches.

The reason for this patch is that only phony goal can depend on phony targets.
But with protobuf we will have to execute phony targets prior to main target
build.
So, this patch set add few new goals and dependences:

1) "all" become default goal.
2) new goals "deps" and "preq" introduced.
3) "all" depends on "deps" and "crtools".
4) All global goals like "zdtm" and "test-legacy" now depends on "all".

where fd is taken from stack and what is worse -- we work
with root privilegues, thus dumping _anything_ from stack
is very bad idea.
