Add a library class, and a UEFI_DRIVER lib instance, that are layered on
top of PciCapLib, and allow clients to plug an EFI_PCI_IO_PROTOCOL backend
into PciCapLib, for config space access.
(Side note:
Although the UEFI spec says that EFI_PCI_IO_PROTOCOL_CONFIG() returns
EFI_UNSUPPORTED if "[t]he address range specified by Offset, Width, and
Count is not valid for the PCI configuration header of the PCI
controller", this patch doesn't directly document the EFI_UNSUPPORTED
error code, for ProtoDevTransferConfig() and its callers
ProtoDevReadConfig() and ProtoDevWriteConfig(). Instead, the patch refers
to "unspecified error codes". The reason is that in edk2, the
PciIoConfigRead() and PciIoConfigWrite() functions [1] can also return
EFI_INVALID_PARAMETER for the above situation.
Namely, PciIoConfigRead() and PciIoConfigWrite() first call
PciIoVerifyConfigAccess(), which indeed produces the standard
EFI_UNSUPPORTED error code, if the device's config space is exceeded.
However, if PciIoVerifyConfigAccess() passes, and we reach
RootBridgeIoPciRead() and RootBridgeIoPciWrite() [2], then
RootBridgeIoCheckParameter() can still fail, e.g. if the root bridge
doesn't support extended config space (see commit 014b472053).
For all kinds of Limit violations in IO, MMIO, and config space,
RootBridgeIoCheckParameter() returns EFI_INVALID_PARAMETER, not
EFI_UNSUPPORTED. That error code is then propagated up to, and out of,
PciIoConfigRead() and PciIoConfigWrite().

Add a library class, and a BASE lib instance, that are layered on top of
PciCapLib, and allow clients to plug a PciSegmentLib backend into
PciCapLib, for config space access.
(Side note:
The "MaxDomain" parameter is provided because, in practice, platforms
exist where a PCI Express device may show up on a root bridge such that
the root bridge doesn't support access to extended config space. Earlier
the same issue was handled for MdeModulePkg/PciHostBridgeDxe in commit
014b472053. However, that solution does not apply to the PciSegmentLib
class, because:
(1) The config space accessor functions of the PciSegmentLib class, such
as PciSegmentReadBuffer(), have no way of informing the caller whether
access to extended config space actually succeeds.
(For example, in the UefiPciSegmentLibPciRootBridgeIo instace, which
could in theory benefit from commit 014b472053, the
EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() status code is explicitly
ignored, because there's no way for the lib instance to propagate it
to the PciSegmentLib caller. If the
EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() call fails, then
DxePciSegmentLibPciRootBridgeIoReadWorker() returns Data with
indeterminate value.)
(2) There is no *general* way for any firmware platform to provide, or
use, a PciSegmentLib instance in which access to extended config space
always succeeds.
In brief, on a platform where config space may be limited to 256 bytes,
access to extended config space through PciSegmentLib may invoke undefined
behavior; therefore PciCapPciSegmentLib must give platforms a way to
prevent such access.)

The ElfConvert routines in GenFw don't handle the ".eh_frame" ELF section
emitted by gcc. For this reason, Leif disabled the generation of that
section for AARCH64 with "-fno-asynchronous-unwind-tables" in commit
28e80befa4 [1], and Ard did the same for IA32 and X64 in commit
26ecc55c02 [2]. (The CLANG38 toolchain received the same flag at its
inception, in commit 6f756db5ea [3].)
However, ".eh_frame" is back now; in upstream gcc commit 9cbee213b579 [4]
(part of tag "gcc-8_1_0-release"), both "-fasynchronous-unwind-tables" and
"-funwind-tables" were made the default for AARCH64. (The patch author
described the effects on the gcc mailing list [5].) We have to counter the
latter flag with "-fno-unwind-tables", otherwise GenFw chokes on
".eh_frame" again (triggered for example on Fedora 28).
"-f[no-]unwind-tables" goes back to at least gcc-4.4 [6], so it's safe to
add to GCC_AARCH64_CC_FLAGS.

Call Tcg2PhysicalPresenceLibProcessRequest() to process pending PPI
requests from PlatformBootManagerAfterConsole().
Laszlo understanding of edk2 is that the PPI operation processing was
meant to occur *entirely* before End-Of-Dxe, so that 3rd party UEFI
drivers couldn't interfere with PPI opcode processing *at all*.
He suggested that we should *not* call
Tcg2PhysicalPresenceLibProcessRequest() from BeforeConsole(). Because,
an "auth" console, i.e. one that does not depend on a 3rd party
driver, is *in general* impossible to guarantee. Instead we could opt
to trust 3rd party drivers, and use the "normal" console(s) in
AfterConsole(), in order to let the user confirm the PPI requests. It
will depend on the user to enable Secure Boot, so that the
trustworthiness of those 3rd party drivers is ensured. If an attacker
roots the guest OS from within, queues some TPM2 PPI requests, and
also modifies drivers on the EFI system partition and/or in GPU option
ROMs (?), then those drivers will not load after guest reboot, and
thus the dependent console(s) won't be used for confirming the PPI
requests.

The PeriodicSmiDispatchFunction() in SmmPeriodicSmiLib may assert

Currently, the SetActivePeriodicSmiLibraryHandler() function
(invoked at the beginning of the PeriodicSmiDispatchFunction()
function) attempts to locate the PERIODIC_SMI_LIBRARY_HANDLER_CONTEXT
structure pointer for the current periodic SMI from a given
EFI_SMM_PERIODIC_TIMER_REGISTER_CONTEXT (RegiserContext) structure
pointer (using the CR macro).
The RegisterContext structure pointer passed to the
PeriodicSmiDispatchFunction() is assumed to point to the same
RegisterContext structure address given to the
SmmPeriodicTimerDispatch2 protocol Register() API in
PeriodicSmiEnable().
However, certain SmmPeriodicTimerDispatch2 implementation may copy
the RegisterContext to a local buffer and pass that address as the
context to PeriodicSmiDispatchFunction() in which case usage of the
CR macro to find the parent structure base fails.
The patch uses the LookupPeriodicSmiLibraryHandler() function to
find the PERIODIC_SMI_LIBRARY_HANDLER_CONTEXT structure pointer.
This works even in this scenario since the DispatchHandle returned
from the SmmPeriodicTimerDispatch2 Register() function uniquely
identifies that registration.
