push CPUID level to 4 to allow Intel multicore decoding

Intel CPUs store the number of cores in CPUID leaf 4. So push
the maxleaf value to 4 to allow the guests access to this leaf.

set CPUID bits to present cores and threads topology

Controlled by the enhanced -smp option set the CPUID bits to present the
guest the desired topology. This is vendor specific, but (with the exception
of the CMP_LEGACY bit) not conflicting, so we set all bits everytime....

allow overriding of CPUID level on command line

The CPUID level determines how many CPUID leafs are exposed to the guest.
Some features (like multi-core) cannot be propagated without the proper
level, but guests maybe confused by bogus entries in some leafs....

cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal

handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations. This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets...

Unbreak large mem support by removing kqemu

kqemu introduces a number of restrictions on the i386 target. The worst is that
it prevents large memory from working in the default build.

Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on...

Only allow -cpu host when KVM is enabled

-cpu host is not at all useful when using tcg.

omit 3DNOW! CPUID bits from qemu64 CPU model

Since we recently do not disable 3DNOW! support anymore, we should
avoid setting the bits in the default qemu64 CPU model to ease
migration. TCG does not support it anyway and even AMD deprecates
it's usage nowadays....
