Instead of parsing the whole cpu_model string inside
cpu_x86_find_by_name(), first split it into the CPU model name and the
full feature string, then parse the feature string into pieces.

When using CPU model classes, those two pieces of information will be
used at different moments (CPU model name will be used to find CPU
class, feature string will be used after CPU object was created), so
making the split in two steps will make it easier to refactor the code
later.

This should also help on the CPU properties work, that will just need to
replace the cpu_x86_parse_featurestr() logic (and can keep the CPU model
lookup code as-is).

hw_error() is specific for fatal hardware emulation errors, not for
internal errors related to the qdev object/class abstraction or object
initialization.

Replace it with an error_report() call, followed by abort().

This will also help reduce dependencies of the qdev code (as hw_error()
is from cpus.o, and depends on the CPU list from exec.o).

It just needs the Monitor and DeviceState typedefs, so it doesn't need

Instead of keeping all those struct typedefs in qemu-common.h, move it
to a header that can be safely included by other headers, containing
only the struct typedefs and not pulling in other dependencies.

Also, move some of the qdev-core.h typedefs to the new file, too, so
other headers don't need to include qdev-core.h only because of
DeviceState and other typedefs.

This will help us remove qemu-common.h dependencies from some headers
later.
