This is the second patch in series of implementing NETLINK_GENERIC
protocol decoder.
This change allows passing of opaque user data to the callback function.
* socketutils.c (receive_responses): Change the type of proto_name
argument from "const char *" to "void *" to allow passing
of arbitrary data to the callback function.
Rename proto_name to opaque_data, make it the last argument.
Pass it to the callback function as the last argument.
(inet_parse_response, unix_parse_response, netlink_parse_response):
Change the type of proto_name argument from "const char *" to "void *",
rename it to opaque_data, make it the last argument.
Introduce a local variable proto_name to convert the type
of opaque_data argument from "void *" to "const char *".
(unix_get, inet_get, netlink_get): Cast the protocol name from
"const char *" to "void *" for passing to the callback function.

This is the first patch in series of implementing NETLINK_GENERIC
protocol decoder.
receive_responses was written for decoding kernel responses of type
SOCK_DIAG_BY_FAMILY, other types were ignored.
This change makes the type of netlink response a parameter
so the function can be used for other types of communication.
* socketutils.c (receive_responses): add a new parameter
expected_msg_type to handle types other than SOCK_DIAG_BY_FAMILY.

in xlat/netlink_flags.in file.

Some of XFRM_MSG_* constants were introduced later than the header file
where they are defined.
* xlat/nl_xfrm_types.in: Add default values for constants.
This change removes the trace_syscall function. Now, the code that uses
syscall.c trace functions is expected to check whether it is a syscall
entry or exit (with entering(tcp)/exiting(tcp)) itself, and then make
an appropriate sequence of function calls.
* defs.h: Update comment on TCB_INSYSCALL.
(trace_syscall): Remove prototype.
(syscall_entering_decode, syscall_entering_trace,
syscall_entering_finish, syscall_exiting_decode, syscall_exiting_trace,
syscall_exiting_finish): New prototypes.

add a string argument.
(create_nl_socket): New macro wrapper around create_nl_socket_ext.
* tests/create_nl_socket.c (create_nl_socket): Rename
to create_nl_socket_ext, add a string argument, include it
in diagnostic messages.

netlink family argument. All callers updated.
