network/stack: Get rid of socket_readv and socket_writev.

These have not been used in years (maybe since the redesign of the
network stack?). Only socket_writev had an implementation, which was
mostly just an incomplete version of socket_send.

Scatter/gather I/O is already supported via msghdr's msg_iov/len fields,
so this is redundant anyway.

net_socket: control op should be uint32.

Where it is called from stack_interface_ioctl, the parameter
is already a uint32 there.

Fixes #13826.

* Made an uint32 out of net_socket::bound_to_device.

* Introduced a datalink layer (2) independent way of specifying the packet
type one wants to receive. Changed ipv6_datagram to use that (but note that
it currently does not compile).
* Header cleanup.

* net_socket_module_info::acquire_socket() now returns whether or not the
socket could be acquired, ie. when its reference count is 0, it cannot be
acquired anymore. This requires the protocol to do proper locking, though.
* The TCP EndpointManager now checks the return value of acquire_socket(), and
only returns the endpoint if that succeeded.
* This fixes bug #2197.
* Minor cleanup.

* Sockets now inherit from WeakReferenceable.
* This fixes the problem when a socket changes something with regards to its
parent.

* Actually implemented the SO_BINDTODEVICE socket option I added some time ago.
* This makes it possible to select a specific device, even if no interface
has been configured for it yet. To make it work, each interface now has a
private direct route which will be returned if a socket is bound to a device.
* This will be used for example in DHCP to make it work when more than one
adapter is attached.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27983 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed THREAD_FLAGS_IOCTL_SYSCALL to THREAD_FLAGS_SYSCALL,
syscall_restart_ioctl_is_restarted() to syscall_restart_is_restarted,
IoctlSyscallFlagUnsetter to SyscallFlagUnsetter, and
IoctlSyscallRestartWrapper to SyscallRestartWrapper, as they are no
longer only used for ioctl().
* Removed unused syscall_restart_ioctl_handle_post().
* Made SyscallRestartWrapper a lot fancier. Instead of storing a
reference to the result value, it stores the value itself, and it
features all the interesting operators that make it appear like that
value. This simplifies the use of the class quite a bit.
* THREAD_FLAGS_SYSCALL is now set for all socket function and the
read[v](), write[v]() syscalls.
* Added is_syscall() function and net_stack hook to the net stack.
* Removed "kernel" parameter from all net_stack_interface and net_socket
module hooks. They aren't need any longer, since is_syscall() can be
used instead.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24914 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the way the socket functions work:
- The net_stack driver is no longer used. Instead we have a kernel
module which is directly used by syscall implementations in the
kernel. I.e. we no longer tunnel those functions through ioctls, but
have normal syscalls.
- Removed the superfluous net starter module.
- Implemented the FDTYPE_SOCKET type file_descriptors, that is sockets
are no longer vnode based.
- Adjusted libnetwork (the socket function implementations)
accordingly.
- Adjusted netstat accordingly.
* Socket module:
- Implemented socketpair().
- Added "kernel" parameter to the control hook. Quite a few more hooks
would actually need the parameter, but I didn't change those yet,
since that would probably also require changes to the protocol
module interface.

* int32_t, uint32_t are now of type "int", and no longer of type "long".
This should help to reduce the number of warnings imported code will throw
during compilation (helps a lot with tcpdump, for example).
* Since long is 64 bit on 64 bit platforms, we might want to think about doing
that change for the Haiku types int32 and uint32 as well.
* Fixed several occurences of hidden type problems.
* Fixed build of the stack and TCP under BeOS.
* Fixed incorrect typedef in socket_interface.h.
* Minor cleanup.

some getsockopt/setsockopt and multicast fixes.

* allow an ipv4 bind() to a multicast address.
* bumped getsockopt/setsockopt kernel driver buffers to 256 bytes to at least handle structures which take one sockaddr_storage.
* convert generic multicast delta API names to IPv4 ones before handling the specific option.
* changed ipv4_getsockopt/ipv4_setsockopt a bit as the code gcc 2.95 was generating was a bit too funky.
* properly pass setsockopt/getsockopt to handling protocols.

- Properly flag sockets using non-blocking connects() when in SYN SENT.
- and when in LISTEN, we should use the socket's connection queue size.

- remove transfer_args processing from strace since the structure was removed

a bit clearer.

replacing files when merging when you don't have deleted them manually (for some reason,

that same limitation).
