x86: Add MSR whitelisting to to-do list
We currently allow access to almost all MSRs (except for APIC-related
ones). This has to be changed into a whitelist approach to avoid that
the cell manipulates a CPU state in a way we didn't validate as safe.

Log Message:
-----------
core: Introduce error return code tracing
A number of errors that can be reported during setup or while
reconfiguring cells are hard to trace down to their detailed reasons
because of the limited number of error codes available through POSIX.
This Introduces a non-invasive mechanism to instrument error return
paths in the hypervisor and report the origin of a specific error code
in the form
hypervisor/arch/x86/vmx.c:592: returning error -ENODEV
This can then be matched against the source code to find out which check
on the hardware, the system state or the configuration data failed
precisely.
The feature is off by default, requiring CONFIG_TRACE_ERROR to be set in
config.h.

core: Instrument relevant return paths for error tracing
This instruments return paths so that the origin of important errors can
be tracked down. Two so far explicit error outputs are replaced with
trace_error.
We do not instrument -ENOMEM cases unless they relate to allocations
from the remapping pool. All other -ENOMEM cases boil down to a too
small hypervisor region.

This Introduces a non-invasive mechanism to instrument error return
paths in the hypervisor and report the origin of a specific error code
in the form
hypervisor/arch/x86/vmx.c:592: returning error -ENODEV
This can then be matched against the source code to find out which check
on the hardware, the system state or the configuration data failed
precisely.
The feature is off by default, requiring CONFIG_TRACE_ERROR to be set in
config.h.

core: Instrument relevant return paths for error tracing
This instruments return paths so that the origin of important errors can
be tracked down. Two so far explicit error outputs are replaced with
trace_error.
We do not instrument -ENOMEM cases unless they relate to allocations
from the remapping pool. All other -ENOMEM cases boil down to a too
small hypervisor region.

Make sure we test both CONFIG_TRACE_ERROR enabled and disabled by
leaving it off for the Banana Pi, and also test it on both
architectures.

Just take the ROM memory region as one, that avoids creating unalligned
