The names of supported CPU models instead of CPU types should be
printed when the user specified CPU type isn't supported, to be
consistent with the output from '-cpu ?'.
Correct the error messages to print CPU model names instead of CPU
type names.

It's no sense to check the CPU type when mc->valid_cpu_types[0] is
NULL, which is a program error. Raise an assert on this.
A precise hint for the error message is given when mc->valid_cpu_types[0]
is the only valid entry. Besides, enumeration on mc->valid_cpu_types[0]
when we have mutiple valid entries there is avoided to increase the code
readability, as suggested by Philippe Mathieu-Daudé.
Besides, @cc comes from machine->cpu_type or mc->default_cpu_type. For
the later case, it can be NULL and it's also a program error. We should
use assert() in this case.

The logic, to check if the specified CPU type is supported in
machine_run_board_init(), is independent enough. Factor it out into
helper is_cpu_type_supported(). machine_run_board_init() looks a bit
clean with this. Since we're here, @machine_class is renamed to @mc to
avoid multiple line spanning of code. The comments are tweaked a bit
either.
No functional change intended.

[PMD: Only call new helper if machine->cpu_type is not NULL]
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
Functions that use an Error **errp parameter to return errors should
not also report them to the user, because reporting is the caller's
job. The principle is violated by machine_run_board_init() because
it calls error_report(), error_printf(), and exit(1) when the machine
doesn't support the requested CPU type.
Clean this up by using error_setg() and error_append_hint() instead.
No functional change, as the only caller passes &error_fatal.

Add a helper to return a machine default CPU type.
If this machine is restricted to a single CPU type,
use it as default, obviously.

For all targets, the CPU class returned from CPUClass::class_by_name()
and object_class_dynamic_cast(oc, CPU_RESOLVING_TYPE) need to be
compatible. Lets apply the check in cpu_class_by_name() for once,
instead of having the check in CPUClass::class_by_name() for individual
target.

however have all_sources() and all_dependencies() methods that

The sgx_epc_get_section stub is reachable from cpu_x86_cpuid. It
should not assert, instead it should just return true just like
the "real" sgx_epc_get_section does when SGX is disabled.
