block: Disable driver-specific options for 1.5
We don't want to commit to the API yet before everything is worked out.
Disable it for the 1.5 release. This commit is meant to be reverted
after the 1.5 release.
The disabling of the driver-specific options is achieved by applying the
old checks while parsing the command line.

pc: Kill the "use flash device for BIOS unless KVM" misfeature
Use of a flash memory device for the BIOS was added in series "[PATCH
v10 0/8] PC system flash support", commit 4732dca..1b89faf, v1.1.
Flash vs. ROM is a guest-visible difference. Thus, flash use had to
be suppressed for machine types pc-1.0 and older. This was
accomplished by adding a dummy device "pc-sysfw" with property
"rom_only":
* Non-zero rom_only means "use ROM". Default for pc-1.0 and older.
* Zero rom_only means "maybe use flash". Default for newer machines.
Not only is the dummy device ugly, it was also retroactively added to
the older machine types! Fortunately, it's not guest-visible (thus no
immediate guest ABI breakage), and has no vmstate (thus no immediate
migration breakage). Breakage occurs only if the user unwisely
enables flash by setting rom_only to zero. Patch review FAIL #1.
Why "maybe use flash"? Flash didn't (and still doesn't) work with
KVM. Therefore, rom_only=0 really means "use flash, except when KVM
is enabled, use ROM". This is a Bad Idea, because it makes enabling/
disabling KVM guest-visible. Patch review FAIL #2.
Aside: it also precludes migrating between KVM on and off, but that's
not possible for other reasons anyway.
Fix as follows:
1. Change the meaning of rom_only=0 to mean "use flash, no ifs, buts,
or maybes" for pc-i440fx-1.5 and pc-q35-1.5. Don't change anything
for older machines (to remain bug-compatible).
2. Change the default value from 0 to 1 for these machines.
Necessary, because 0 doesn't work with KVM. Once it does, we can flip
the default back to 0.
3. Don't revert the retroactive addition of device "pc-sysfw" to older
machine types. Seems not worth the trouble.
4. Add a TODO comment asking for device "pc-sysfw" to be dropped once
flash works with KVM.
Net effect is that you get a BIOS ROM again even when KVM is disabled,
just like for machines predating the introduction of flash.
To get flash instead, use "--global pc-sysfw.rom_only=0".

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:

In certain scenario, latency induced by paging is significant and
memory locking is needed. Also, in the scenario with untrusted
guests, latency improvement due to mlock is desired.
This patch introduces a following new option to mlock guest and
qemu memory:
-realtime mlock=on|off

qemu-char: do not operate on sources from finalize callbacks
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.

qemu-char: correct return value from chr_read functions
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.

qemu-char: simplify pty polling
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
/dev/pts/4,raw").
