Change functions declared as taking unspecified number of arguments
of unspecified type to functions that take no arguments.
Reported by kernel's checkpatch.pl script.

hardware timestamps, which are typically enabled by NTP and PTP
implementations.

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.

Add printflags_ex extension over printflags64 that, similar
to printxvals, takes a NULL-terminated sequence of xlat pointers.
* defs.h (printflags_ex): New prototype.
(printflags64): Turn into a thin wrapper around printflags_ex.
* netlink.c (decode_nlmsg_flags): Use printflags_ex.

* xlat/netlink_get_flags.in: Remove entries listed
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.
* strace.c (trace_syscall): New static replacement for old trace_syscall.

(trace_syscall_entering): Split into ...
(syscall_entering_decode, syscall_entering_trace,
syscall_entering_finish): ... new functions.
(trace_syscall_exiting): Split into ...
(syscall_exiting_decode, syscall_exiting_trace,
syscall_exiting_finish): ... new functions.
nfnetlink was introduced in linux by commit v2.6.14-rc1~1035^2~217,
add a guard for the case when system headers are not fresh enough.

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.
Implement a pluggable mechanism of nlmsg_type decoding.
Add decoding of NETLINK_SOCK_DIAG types.
* linux/sock_diag.h (SOCK_DESTROY): New macro.
* xlat/nl_sock_diag_types.in: New file.
* netlink.c: Include xlat/nl_sock_diag_types.h.
(get_fd_nl_family, decode_nlmsg_type): New functions.
