ae92cbd542 chardev: Basic support for TN3270
This introduces basic support for TN3270, which needs to negotiate
three Telnet options during handshake:
  - End of Record
  - Binary Transmission
  - Terminal-Type

As a basic implementation, this simply ignores NOP and Interrupt
Process(IP) commands. More work should be done for them later.

For more details, please refer to RFC 854 and 1576.

b19456dd0e 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 b43decb015,
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.

8487ce45f8 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().
