Peeloff feature of SCTP association creates a new socket which is not
set to nonblocking.
Function for receving data is shared with udp which has a default
loop when reading packets which is set to 5.
Calling the receive function more then once, is fine as long as
there are more data to receive or socket are nonblocking.
Set new peeled off socket to be nonblocking to prevent a erlang vm hangup.

Long input paths (longer than MAX_PATH) would get copied
into a buffer of size MAX_PATH for read_link and altname
in efile_drv.
Also fixed misuse of size_t parameter as wchar_t *
string length in win_efile:efile_readlink.

Also allow mixed address families to bind, since the first address on
a multihomed sctp socket must be bound with bind, while the rest are
to be bound using sctp_bindx.
At least Linux supports adding address of mixing families.
Make inet_set_faddress function available also when HAVE_SCTP is not
defined, since we use it to find an address for bind to be able to mix
ipv4 and ipv6 addresses.

These variables are normally declared by <netinet/in.h>,
but for instance not on Windows 7, SDK 7.1.
Work around that by using IN6ADDR_ANY_INIT and IN6ADDR_LOOPBACK_INIT
if present, fallback to using :: and ::1.

Setting several ip addresses for an SCTP socket worked only for IPv4
on Linux. For IPv6 and for other for instance Solaris and FreeBSD, it
failed with badarg for both IPv4 and IPv6.
For the first address specified to gen_sctp:open, bind is now called,
while for any following addresses, sctp_bindx is called, repeatedly,
with one address at a time. Previously, sctp_bindx was called for all
addresses in one go, with the addresses in reverse order, and bind was
not called at all if more than one address was specified. Both
Solaris and FreeBSD requires bind to have been called before calling
sctp_bindx, and FreeBSD additionally allows at most one address at a
time in the call to sctp_bindx.
For some versions of Linux, for instance SuSE 10, the port can be 0
only for the call to bind but not for subsequent calls to sctp_bindx,
so replace with the port number assigned by the operating system.

Set appropriate values for the sockaddr length fields---sai.sin_len
and sai6.sin6_len---if those fields exist; rely on the NO_SA_LEN
configure check to see if they exist. The length field exists on at
least FreeBSD, and there it needs to have a proper value for instance
in the call to sctp_bindx, or else that will fail with EINVAL.

Ensure displayed sizes are not negative.

This significantly reduces latency for tcp servers
with high load, as we need not go into poll to get
the next message. Maximum throughput may increase
between 4 to 6 times compared to R15B.

User tags in a dynamic trace enabled VM are spread throughout the system
in the same way as seq_trace tokens. This is used by the file module
and various other modules to get hold of the tag from the user process
without changing the protocol.

Add probes to (mostly) the efile_drv.c driver and other

Since stop_select is called at an arbitrary point in the future
it would sometime not be alled before the tcp driver started
selecting on the fd. So now ERL_DRV_USE_NO_CALLBACK is used
so that the stop_select call is never made.
This seems to only have happened OS X.

The return value from efile_sendfile was not consistent
inbetween platforms. The API should now be working as it
was intended.

We use the fact that file_flush is called when there is
data in the driver queue when a port is closed to ensure
that all data is cleaned up as it should.

zip,unzip,gzip,gunzip,compress and uncompress did not close the port
when given invalid data argument. Fixed by putting close in "try-after".
A closed port could in same cases get stuck in limbo due to data in
io-queue. Fixed by adding a flush callback.

This prevents building for operating systems that do not yet have IPv6
compatible socket API. Error can be reproduced by (cross)building for
a os that doesn't have these headers. This will abort with a error
about incomplete type 'struct in6_addr'. All other uses of IPv6 API
in inet_drv.c are conditionalized like in the patch.

The {error, enfile} return value is badly misleading and confusing for
this case, since the Posix ENFILE errno value has a well-defined meaning
that has nothing to do with Erlang ports. The fix changes the return
value to {error, system_limit}, which is consistent with e.g. various
file(3) functions. inet:format_error/1 has also been updated to support
system_limit in the same manner as file:format_error/1.
