Subject: [PATCH 12/20] smbios: rename/expose structures/bitmaps used by both
legacy and modern code
RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS
RH-Jira: RHEL-21705
RH-Acked-by: MST <mst@redhat.com>
RH-Acked-by: Ani Sinha <None>
RH-Commit: [10/18] 59fe438d5b7f6e584a6bb02597e4d4724fe2cece
JIRA: https://issues.redhat.com/browse/RHEL-21705
As a preparation to move legacy handling into a separate file,
add prefix 'smbios_' to type0/type1/have_binfile_bitmap/have_fields_bitmap
and expose them in smbios.h so that they can be reused in
legacy and modern code.
Doing it as a separate patch to avoid rename cluttering follow-up
patch which will move legacy code into a separate file.

Conflicts: hw/smbios/smbios.c
due to setting downstream type1.family/type1.sku defaults
