qga: distinguish binary modes in "guest_file_open_modes" map

In Windows guests this may make a difference.

Since the original patch (commit c689b4f1) sought to be pedantic and to
consider theoretical corner cases of portability, we should fix it up
where it failed to come through in that pursuit.

main-loop: narrow win32 pollfds_fill() event bitmasks

pollfds_fill() and pollfds_poll() translate GPollFD to rfds/wfds/xfds
for sockets on win32.  select(2) is the underlying system call which is
used to monitor sockets for activity.

Currently file descriptors that monitor G_IO_ERR will be included in
both rfds and wfds.  As a result, select(2) will report writability on
file descriptors where we only really wanted to monitor readability
(with errors).

slirp_pollfds_poll() hit this issue: UDP sockets are blocking sockets so
we hang in sorecvfrom() when G_IO_ERR is set due to the socket being
writable (we only wanted to check for readability).

This patch fixes the slirp_pollfds_poll() hang.

Revert "migration: don't account sleep time for calculating bandwidth"

This reverts commit 7161082c8d8cf167c508976887a0a63f4db92b51.

Reverting this patch fixes a divide-by-zero error in qemu that can be
fairly reliably triggered by doing block migration. In this case, the
configuration/error was:

This revert potentially re-introduces a bug that was present in 1.4,
but fixes a prevalent issue with block migration so we should revert
it for now and take an updated patch later.
