APEI are ACPI4.0 new features. It consists of ERST, BERT, HEST, and
EINJ. ERST is used to save fault error log to a platform persistent
storage, so that when reboot os can retrieve the error log and handle
it.
This patch is used to implement ERST feature to Xen. It consists of
3-level hierarchy: operation level, action level, and instru= ction
level. Instruction do basic io; Action done by sequential
instructions parsed from ACPI ERST table; Operation done by
sequential actions defined by ACPI spec, providing erst_write/
erst_read/ erst_clear interfaces to MCE/ NMI/ PCIe error handling
mechanism, etc.

Replaces libxl_free_vcpu_list.
The ->cpumap field is now always a unique allocation rather than each
being an offset into the cpumap allocated in the first
libxl_device_pci in the list.
Refactor vcpulist so that the two cases can share more code.

As well as freeing data any file mappings need to be torn down so
implement an explicit destroy function.
Also the map and unmap function are internal to libxl so make that so.

libxl_dominfo, libxl_poolinfo, libxl_vminfo, libxl_domain_build_state,
libxl_physinfo and libxl_sched_credit contain no members which require
destruction so omit the auto generated destructor.
As an exception continue to generate destructors for libxl_device_*
and libxl_{devtype}* even if they have no interesting members so that
all device types can be treated the same without special knowledge
about the type contents being required.

This field always refers to a libxl_domain_build_state structure which
is managed already by the caller, therefore it is incorrect to free it
as part of libxl_device_console_destroy.
(arguably this field should be a copy of, not a reference too, the original)

I chose the name "_destroy" rather than "_free" because the destructor
functions will free only the members of a type recursively but will
not free the actual type structure itself. The allocation of the type
is typically done by the caller and may not be a single allocation,
e.g. lists/arrays of types or embedded in other structures etc.
The exceptions to this rule are libxl_string_list_destroy and
libxl_key_value_list_destroy but I'm not 100% convinced they are
exceptions (since they are kind-of opaque) and I couldn't see a
cleanerway to express this concept. I have made a best effort attempt
to implement these functions sanely but since as far as I can tell
nothing in the current code base ever sets
libxl_domain_create_info.{xsdata,platformdata} I'm flying somewhat
blind.

The libxl interface types are represented by a simple python data
structure (which could be parsed from a bespoke language in the
future).
This will allow the autogeneration of functions to free the component
members of the libxl types. In the future it may also enable auto
generation of type marshalling code for language bindings.
The generated file should be identical to before with the exception of
the "DO NOT EDIT" header.
It was unfortunately necessary to add explcit an dependency on
_libxl_types.h (indirectly via libxl.h) to all C files since the
autogenerated dependencies are not available in time.

libxl_console_constype is an enum and can therefore be unsigned so
using -1 as a sentinel for unset in main_console fails to work as
expected.
Arrange for all valid enum values to be > 0 and use 0 as the sentinal
instead.
If the user does not request a specific type then always use the
primary console since using "-n" but not "-t" is not meaningful as we
do not know which type to request.
Also make libxl_console_exec reject invalid values of type.

The per-thread hypercall buffer is usually cleaned up on pthread_exit
by the destructor passed to pthread_key_create. However if the calling
application is not threaded then the destructor is never called.
This frees the data for the current thread only but that is OK since
any other threads will be cleaned up by the destructor.
Changed since v1:
* Ensure hcall_buf_pkey is initialised before use. Thanks to
Christoph Egger for his help diagnosing this issue on NetBSD.
* Remove redundant if (hcall_buf) from xc_clean_hcall_buf since
_xc_clean_hcall_buf includes the same check.

Since the recent build error caused by mismatch of symbol types due to
missing declarations, build libxl with -Wmissing-declarations.
The patch is mostly straightforward, a one liner in the makefile enables
the flag, a lot of functions in xl_cmdimpl.c needed to be made static
and libxl_paths.c needed to include libxl.h.
The one wart on the patch-set is that flex has a bug where it emits code
with missing declarations for yy(set|get)_column. This can be worked
around by providing the declarations ourselves regardless.
