v6: 5aug2021
 - Fixed compile warning/error, per Michael Tsirkin
 - Fixed mingw32 build error, per Michael
 - Converted exchange buffer to MemoryBackend, per Igor
 - Migrated test to PCI, per Igor
 - Significantly reduced amount of copying, per Igor
 - Corrections/enhancements to acpi_erst.txt, per Igor
 - Many misc/other small items, per Igor

v5: 30jun2021
 - Create docs/specs/acpi_erst.txt, per Igor
 - Separate PCI BARs for registers and memory, per Igor
 - Convert debugging to use trace infrastructure, per Igor
 - Various other fixups, per Igor

v4: 11jun2021
 - Converted to a PCI device, per Igor.
 - Updated qtest.
 - Rearranged patches, per Igor.

v3: 28may2021
 - Converted to using a TYPE_MEMORY_BACKEND_FILE object rather than
   internal array with explicit file operations, per Igor.
 - Changed the way the qdev and base address are handled, allowing

   existing code.
