8ba2c0159f sock/posix: Set sendbuf and recvbuf before connect call
For client side connections, SO_RCVBUF needs to set
before connect call() so this patch moves those calls
accordingly.

8c37b10702 sock/posix: fix potential segfault in zero-copy
CMSG_FIRSTHDR could theoretically return NULL. Check it for the
peace of mind.

CMSG_FIRSTHDR() returns a pointer to the first cmsghdr in the
          ancillary data buffer associated with the passed msghdr.
          It returns NULL if there isn't enough space for a cmsghdr
          in the buffer.

08249f00b5 sock/posix: Change the return type of function _sock_check_zcopy
Purpose: The function spdk_sock_request_put may
return an error code, and close the socket, so we should change the
return type of  _sock_check_zcopy.

If the return value of  _sock_check_zcopy is not zero,
we should not handle the EPOLLIN event.

Fixes #1169

be6aa42708 sock/vpp: Add spdk_vpp_sock_writev_async support
Purpose: To support SPDK iSCSI target applications
when it uses spdk_sock_writev_async.

PS: for some duplicated code between posix and vpp,
we should consider it later. Since if we do it early,
if it cannot be abstracted in the common header,
it will invoke addtional work.

8e8a5f7c28 nvme/tcp: Use writev_async for sending data on sockets
Amortize the writev syscall cost by using the writev_async socket API.

This allows the socket layer to batch writes into one system call
and also apply further optimizations such as posix's MSG_ZEROCOPY
when they are available. As part of doing so we remove the error
return in the socket layer writev_async implementation for sockets
that don't have a poll group.

Doing so eliminates the send queue processing.

e61b0904a8 sock/posix: Add flush
Initiator drivers (e.g nvme/tcp) don't use poll groups but rather directly
poll the qpair. In this case we want to allow the polling function (e.g

d1a8a7bee1 sock: Add a priority parameter in SPDK_NET_IMPL_REGISTER
Purpose: Prepare for setting priorities for different
kernel based sock implementations.

The g_net_impls list is maintained in decreasing order
according to the priority of each sock implementation.

For examaple, if there are 3 sock implementations, i.e.,
posix (priority = 0), vpp (priority = 1), sock_ut (priority =2),
then the list will be maintained as:
sock_ut -> vpp -> posix.

Then if users use spdk_sock_open/listen with impl_name as NULL,
then the order to try is: sock_ut, vpp, then posix

ab22d249e2 sock/posix: Add a pending list for asynchronous requests
Add an additional queue for requests that have been sent on the network
but aren't complete yet. As of this patch, the code
is still calling writev with no flags in the POSIX layer, so it completes
synchronously. That means requests pass through this new pending list
only very briefly inside of one function.
