Introduces a new utility function: parse_debug_env to avoid code
duplication.
This overrides whatever debug value is set on the corresponding devices
from the command line, and is meant to ease the usage with any
management stack. For libvirt you can set environment variables by
extending the dom namespace, i.e:
<domain type='kvm' id='3' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<qemu:commandline>
<qemu:env name='QEMU_CCID_PASSTHRU_DEBUG' value='4'/>
<qemu:env name='QEMU_CCID_DEBUG' value='4'/>
</qemu:commandline>
</domain>

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
With pipelining it is possible to encounter a finished packet when cleaning
the queue due to a halt. This happens when a non stall error happens while
talking to a real device. In this case the queue on the usb-host side will
continue processing packets, and we can have completed packets waiting in
the queue after an error condition packet causing a halt.
There are 2 reasons to discard the completed packets at this point, rather
then trying to writing them back to the guest:
1) The guest expect to be able to cancel and/or change packets after the
packet with the error without doing an unlink, so writing them back may
confuse the guest.
2) Since the queue does not advance when halted, the writing back of these
packets will fail anyways since p->qtdaddr != q->qtdaddr, so the
ehci_verify_qtd call in ehci_writeback_async_complete_packet will fail.
Note that 2) means that then only functional change this patch introduces
is the printing of a warning when this scenario happens.
Note that discarding these packets means that the guest driver and the device
will get out of sync! This is unfortunate, but should not be a problem since
with a non stall error (iow an io-error) the 2 are out of sync already anyways.
Still this patch adds a warning to signal this happening.
Note that sofar this has only been seen with a DVB-T receiver, which gives
of a MPEG-2 stream, which allows for recovering from lost packets, see:

Due to a glib bug, the finalize callback is called with the GMainContext
lock held. Thus, any operation on the context from the callback will
cause recursive locking and a deadlock. This happens, for example,
when a client disconnects from a socket chardev.
The fix for this is somewhat ugly, because we need to forego polymorphism
and implement our own function to destroy IOWatchPoll sources. The
right thing to do here would be child sources, but we support older
glib versions that do not have them. Not coincidentially, glib developers
found and fixed the deadlock as part of implementing child sources.

Even if a CharDriverState's source is blocked by the front-end,
it must not be dropped. The IOWatchPoll that wraps it will take
care of adding and removing it to the main loop. Only remove
the source when the channel is closed; and in that case, make sure
that the wrapping IOWatchPoll is removed too.
These should just be theoretical bugs.

There is no need to use a timer and pty_chr_read to detect a connected
pty. It is simpler to just call g_poll periodically and check for POLLHUP.
It is done once per second, and only if the pty is disconnected, so it
is cheap enough.
Tested with "-monitor pty" and "-serial mon:pty", both of which work
correctly and do not freeze QEMU. (How to test ptys? "socat -,raw,echo=0
