hypervisor: Fix cleaning of generated files for latest kernels
Recent kernels seem to add their own prefix to clean-files, thus won't
remove our files as the paths gets wrong. We can simply remove $(obj),
that works both for current and older kernels.

Automatic type conversion saved us in all these cases so far, but better
avoid surprises in the future and another finding turned out to be a bug
in fact.
JAILHOUSE_BASE requires special wrapping as it is also used in assembly
(the linker script) where the UL tag is not understood.

driver: Improve input validation to make code scanners happier
We trust the configuration files passed down to the driver already
because they define the isolation set up by the hypervisor and can
therefore screw up the system in various ways.
Nevertheless, we can and should improve basic consistency checks of
config fields that influences allocations and copy operations. This will
detect some corruptions/inconsistencies earlier and also satisfies the
Coverity scanner.

to-be-defined platform hash.

x86: Bring host CR4 into well-defined state during setup
Analogously to CR0: Avoid any uncertainty about the state of CR4 left
behind by Linux: leave the architecturally reserved bits intact, respect
the requirement VMX has on CR4 bits and otherwise set our own state.
Set OSXSAVE if available so that we can execute xsetbv on behalf of the
guest.
The resulting CPU-specific state will once be validated via a
to-be-defined platform hash.
A side effect of this change is the VMX's vcpu_exit will no longer clear
VMXE in CR4 but only in the cached Linux state that arch_cpu_restore
will write back.

-----------
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.

Nevertheless, we can and should improve basic consistency checks of

x86: Add MSR whitelisting to to-do list
We currently allow access to 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.

Analogously to CR0: Avoid any uncertainty about the state of CR4 left
behind by Linux: leave the architecturally reserved bits intact, respect
the requirement VMX has on CR4 bits and otherwise set our own state.
Set OSXSAVE if available so that we can execute xsetbv on behalf of the
guest.
The resulting CPU-specific state will once be validated via a
to-be-defined platform hash.
A side effect of this change is the VMX's vcpu_exit will no longer clear
VMXE in CR4 but only in the cached Linux state that arch_cpu_restore
will write back.

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.
