QIOChannel: Add flags on io_writev and introduce io_flush callback

Add flags to io_writev and introduce io_flush as optional callback to
QIOChannelClass, allowing the implementation of zero copy writes by
subclasses.

How to use them:
- Write data using qio_channel_writev*(...,QIO_CHANNEL_WRITE_FLAG_ZERO_COPY),
- Wait write completion with qio_channel_flush().

Notes:
As some zero copy write implementations work asynchronously, it's
recommended to keep the write buffer untouched until the return of
qio_channel_flush(), to avoid the risk of sending an updated buffer
instead of the buffer state during write.

As io_flush callback is optional, if a subclass does not implement it, then:
- io_flush will return 0 without changing anything.

Also, some functions like qio_channel_writev_full_all() were adapted to
receive a flag parameter. That allows shared code between zero copy and
non-zero copy writev, and also an easier implementation on new flags.

char: Fix removing wrong GSource that be found by fd_in_tag

We use fd_in_tag to find a GSource, fd_in_tag is return value of
g_source_attach(GSource *source, GMainContext *context), the return
value is unique only in the same context, so we may get the same
values with different 'context' parameters.

It is no problem to find the right fd_in_tag by using
g_main_context_find_source_by_id(GMainContext *context, guint source_id)
while there is only one default main context.

But colo-compare tries to create/use its own context, and if we pass wrong
'context' parameter with right fd_in_tag, we will find a wrong GSource to handle.
We tried to fix the related codes in commit b43decb015a6efeb9e3cdbdb80f6547ad7248a4c,
but it didn't fix the bug completely, because we still have some codes didn't pass
*right* context parameter for remove_fd_in_watch().

Let's fix it by record the GSource directly instead of fd_in_tag.

char: remove the right fd been watched in qemu_chr_fe_set_handlers()

We can call qemu_chr_fe_set_handlers() to add/remove fd been watched
in 'context' which can be either default main context or other explicit
context. But the original logic is not correct, we didn't remove
the right fd because we call g_main_context_find_source_by_id(NULL, tag)
which always try to find the Gsource from default context.

Fix it by passing the right context to g_main_context_find_source_by_id().
