We use clock_gettime(CLOCK_REALTIME, ...) to create a simple
timestamp. This is used both for debugging and when writing
error/warning messages (from the nif-code).
The workaround for the absence of this function (on some platforms,
old versions of darwin for example) is to simply skip the timestamp.

Fixed some type size warnings (SCTP related). E.g:
On Solaris 11 (OpenIndiana Hipster) long and int is size 4,
but the way Sint32 def works it first "tests" for long size and
if that is correct, that is chosen (which it is on Solaris 11).
On linux long is size 8, so Sint32 will be defined as int.
...
On Solaris 11 the flags TCP_CONGESTION and SO_BINDTODEVICE
does not exist, so the function(s) n[set|get]opt_str_opt is never
used. So, in order to keep the compiler quiet, we add some if-def
to exclude these functions in this case.

The nif callback functions (nif_open) now instead cause an
'nosup' exception if called (instead of badarg).
The basic type uint16_t, uint32_t and int32_t (C99) replaced
"own" (that is, defined by "us") types Uint16, Uint32 and
Sint32.
The point of this is that our Windows build system seems to
be a bit lacking when it comes to types...
Removed "some stuff" that was if-defed. Different solution
when win32 support for sockets has been improved.
Make sure the socket_*.c util modules are not included
in the building for windows.

Fixed more issues regarding closing sockets. Specifically
with respect to recv calls.
Also, added demonitor for all *current* processes.
Also fixed a buffer overflow problem when writing an
warning message (the timestamp buffer was not large
enough).

Add support for otp level socket options rcvbuf, rcvctrlbuf and
sndctrlbuf. These options define default sizes for these
buffers.
The 'rcvbuf' is used when receiving messages when calling
the recv, recvfrom and recvmsg functions.
The 'rcvctrlbuf' is used for the control message header info
when calling the recvmsg function.
The 'sndctrlbuf' is used for the control message header info
when calling the sendmsg function.

Added function sendmsg/2,3,4. Actually worked on the first try.
Something must be wrong...
Still no supported cmsghdr's (only support headers where the
data part is already a binary, which therefor does not require
any processing). So if the cmsghdrs actually work is unclear.

Added processing or more cmsg headers (for more options).
Now (also) supports: socket:timestamp.
Also various fixes and cleanups.
For some reason calling getopt(Sock, 0, {13, int}) (or similar)
fails with badarg even though the nif-function (nif_getopt) actually
returns a valid value (for instance: {ok, 0}).

Added decoding of the "known" control message options: pktinfo,
recvtos, recvttl and recvorigdstaddr).

It seems to work, with atleast some of the cmsg options.
More testing needed...

Added preliminary support for function recvmsg. At the moment
this only works on *nix (Windows has another function, WSARecvMsg,
which has a slightly different API).
Also we have "no" cmsg decode at the moment (just level and type).

The net nif-module had debug on by default. Fixed this
and also made it an option, just as for the socket nif-module.

Added support for the IP option MULTICAST_IF.

The returned address info was supposed to be a map,
by was instead (still) a record.

Fixed handling of closed in the recv function.
We still need to properly handle when we get
0 bytes of data for other types ock sockets
then stream (its valid for dgram for instance).

The common stuff, like decode and encode of common types
(soch as socket address), has been moved into a util file
(socket_util). The debug stuff has also been moved into its
own file. Also introduced a common include file for common
macros and types.

Started to move the common stuff, such as common utility functions,
debug and encode / decode of basic types.
