36b9a45c3b netconn_write_partly cleanups 
This commit changes netconn_write_partly to use msg.w.offset to set
bytes_written for both blocking and non-blocking connections

This is correct because msg.w.offset is the canonical output from
the do_write call and in the case that not all bytes were written,
(a bug?) returning the full size to the caller is dangerous

Lastly, this commit adds an assert for the blocking case to sanity
check that all the bytes we requested were written.  This will help
catch bugs in do_write

36fa1a97d4 lwip_netconn_do_writemore() cleanups 
This commit makes a couple of cleanups discussed in patch #8882:
  1) msg.w.offset should not be set to 0 in the error case.  It is
     only valid when err == ERR_OK
  2) Remove out-of-date comment which indicated the entire write had
     completed (not true for non-blocking write)

This also updates the documentation on offset to include that offset
is only valid when err == ERR_OK

This reverts commit 62c44138da19a8cd9b100b3050c9697a80d8866f.

Didn't notice due to local changes the ASSERTION was already inside the locks...

4c76fd500c Move write_offset from struct netconn to struct api_msg 
This moves the write_offset variable from struct netconn to struct api_msg

This optimizes the storage by only having the space claimed when it is
needed (during a netconn_write_partly() call) and not throughout the
lifetime of the netconn

This also reduces code space/execution by not having to separately manage
clearing/checking write_offset from the current_msg pointer

Lastly, we also save execution by using msg.w.offset as the output
rather than marshaling the result to msg.w.len. Previously, len was used
as input length of dataptr and output for the write operation.
netconn_write_partly() also has access to msg.w.offset, so we can use
that
