__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.

The warning is invalid: the flagged dereferencing of "InstanceZero" is
gated by a condition that is only satisfied if we dereference
"InstanceZero" *first*.
(Perhaps the analyzer assumes that the OrderedCollectionInsert() call,
just before line 259, can change the value of "PciCap->Key.Instance" via
the last argument:
254 //
255 // Add PciCap to CapList.
256 //
257 Status = OrderedCollectionInsert (CapList->Capabilities, &PciCapEntry,
258 PciCap);
259 if (RETURN_ERROR (Status)) {
That assumption is incorrect.)
Add a comment and an ASSERT().

Add a library class, and a BASE lib instance, to work more easily with PCI
capabilities in PCI config space. Functions are provided to parse
capabilities lists, and to locate, describe, read and write capabilities.
PCI config space access is abstracted away.
