This introduces a qemu-img create option for qcow2 which allows the metadata to
be preallocated, i.e. clusters are reserved in the refcount table and L1/L2
tables, but no data is written to them. Metadata is quite small, so this
happens in almost no time.
Especially with qcow2 on virtio this helps to gain a bit of performance during
the initial writes. However, as soon as create a snapshot, we're back to the
normal slow speed, obviously. So this isn't the real fix, but kind of a cheat
while we're still having trouble with qcow2 on virtio.
Note that the option is disabled by default and needs to be specified
explicitly using qemu-img create -f qcow2 -o preallocation=metadata.

Introduce isa_reserve_irq() which marks an irq reserved and returns
the appropriate qemu_irq entry from the i8259 table.
isa_reserve_irq() is a temporary interface to be used to allocate ISA
IRQs for devices which have not yet been converted to qdev, and for
special cases which are not suited for qdev conversions, such as the
'ferr'.
This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own
the ISA irq table.

Changes:
(1) make isa-bus maintain isa irqs, complain when allocating
already taken irqs.
(2) note that (1) works only for isa devices converted to qdev
already (floppy and ps2/kbd/mouse right now), so more work
is needed to make this really useful.
(3) split floppy init into isa and sysbus versions.
(4) add sysbus->isa bridge & fix -M isapc breakage.

Bug fix for segfault when run as i82551 HW:
Use Extended TBD only when HW supports it (i82558 and up).
Added assertions to guard from such buffer overflow
Introduce the MAX_TCB_BYTE_COUNT macro
Allocate buf big enough as HW needs (MAX_ETH_FRAME_SIZE -> MAX_TCB_BYTE_COUNT)
I don't feel 100% OK with the "s->device >= i82558B" condition
since it relies on the numeric (hex) value of those defines, which currently
is correct, but changes (which I don't forsee now) might break it.

Some features (like multi-core) cannot be propagated without the proper

For injecting multi-core and multi-threading CPU topology into guests
extend the -smp syntax to accommodate cores and threads specification.
Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\
[,socket=nr_sockets][,maxcpus=max_cpus]
smp_value is the legacy value specifying the total number of vCPUs for
the guest. If you specify one of cores, threads or sockets this value
can be omitted. Missing values will be computed to fulfill:
smp_value = nr_cores * nr_threads * nr_sockets
where it will favour sockets over cores over threads (to mimic the
current behavior, which will only inject multiple sockets.)
So -smp 4,threads=2 will inject two sockets with 2 threads each,
-smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1.
If max_cpus (the number of hotpluggable CPUs) is omitted, it will
be set to smp_value.

Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code. However,
get_fp_bit returns the bit number of the condition code, not a
bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)
Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

The ne2k is an ancient card that performs pretty terribly under QEMU. In many
modern OSes, there is no longer drivers available for the ne2k.
Switch the default network adapter to e1000. This card is more widely
suppported and performs rather well under QEMU. There may be very old OSes
that had a ne2k driver but not an e1000 driver but I think this is likely the
exception.
I think the average user is better served with an e1000 vs ne2k.
