[Qemu-devel] [PATCH] char: make io_channel_send be used unconditionally

["Daniel P. Berrange" <berrange@redhat.com>]

The io_channel_send_full() method was used unconditionally, but
the io_channel_send() method was only used from !_WIN32 code
paths. Some versions of Mingw toolchain will complain about
the method being defined but not used as a result.

The io_channel_send() API doesn't really simplify life very
much, so get rid of it and rename io_channel_send_full() to
just be io_channel_send().
