The CSM-based VideoDxe driver is a special UEFI_DRIVER module that both
follows and doesn't follow the UEFI driver model.
Namely, in the Supported and Start members of its Driver Binding Protocol
instance, it consumes the Legacy Bios Protocol directly from the UEFI
protocol database, as opposed to (only) opening protocols on the handle
that it is supposed to bind.
Furthermore, the driver "marks" its own image handle with the
NULL-interface "Legacy Bios" (pseudo-protocol) GUID, in order to "inform
back" the provider of the Legacy Bios Protocol, i.e., LegacyBiosDxe, that
VideoDxe is a "BIOS Thunk Driver" in the system.
Quoting "OvmfPkg/Csm/Include/Guid/LegacyBios.h", such a driver follows the
UEFI Driver Model, but still uses the Int86() or FarCall() services of the
Legacy Bios Protocol as the basis for the UEFI protocol it produces.
In a sense, there is a circular dependency between VideoDxe and
LegacyBiosDxe; each knows about the other. However, VideoDxe is a
UEFI_DRIVER, while LegacyBiosDxe is a platform DXE_DRIVER with a very long
DEPEX. Therefore, for keeping dependencies conceptually intact, first
exclude VideoDxe from the OVMF platforms. Always include the
hypervisor-specific real UEFI video driver.

Note that the pathname
"IntelFrameworkModulePkg/Csm/BiosThunk/VideoDxe/VideoDxe.inf" in the bhyve
platform DSC and FDF files is bogus anyway.

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

Sean reports that having two DEC files under OvmfPkg violates the DEC
spec:
> An EDK II Package (directory) is a directory that contains an EDK II
> package declaration (DEC) file. Only one DEC file is permitted per
> directory. EDK II Packages cannot be nested within other EDK II
> Packages.
This issue originates from commit 656419f922c0 ("Add BhyvePkg, to support
the bhyve hypervisor", 2020-07-31).
Remedy the problem as follows. (Note that these steps are not split to
multiple patches in order to keep Bhyve buildable across the transition.)
(1) Delete "OvmfPkg/Bhyve/BhyvePkg.dec".
(2) Point the [Packages] sections of the Bhyve-specific AcpiPlatformDxe,
BhyveRfbDxe, and BhyveFwCtlLib INF files to "OvmfPkg.dec".
(3) Migrate the artifacts that "BhyvePkg.dec" used to have on top of
"OvmfPkg.dec" as follows:
(3a) Merge the copyright notices from Rebecca Cran and Pluribus Networks
into "OvmfPkg.dec".
(3b) Merge the "BhyveFwCtlLib" class header definition into "OvmfPkg.dec".
(3c) Merge value 0x2F8 for the fixed PcdDebugIoPort into
"BhyvePkgX64.dsc".
(4) Unnest the the Include/Library/ and Library/ subtrees from under
OvmfPkg/Bhyve to the corresponding, preexistent subtrees in OvmfPkg.
The goal is to keep the [Includes] section in the "OvmfPkg.dec" file
unchanged, plus simplify references in "BhyvePkgX64.dsc". Non-library
modules remain under "OvmfPkg/Bhyve/".
(4a) The BhyveFwCtlLib class header, and sole instance, are already
uniquely named, so their movements need not involve file renames.
(4b) Rename the Bhyve-specific PlatformBootManagerLib instance to
PlatformBootManagerLibBhyve, in additon to moving it, for
distinguishing it from OvmfPkg's preexistent lib instance. Apply the
name change to all three of the lib instance directory name, the INF
file, and the BASE_NAME define in the INF file.
(4c) Update lib class resolutions in "BhyvePkgX64.dsc" accordingly.
(5) Replace the "ACPI table storage" FILE_GUID in
"OvmfPkg/Bhyve/AcpiTables/AcpiTables.inf" with a new GUID, and
open-code the "ACPI table storage" GUID in the "ACPITABLE" FDF rule
instead, replacing $(NAMED_GUID). This step is necessary because CI
requires unique FILE_GUIDs over all INF files, and OVMF's original
"AcpiTables.inf" already uses the "ACPI table storage" GUID as
FILE_GUID.
