This patch enhances error handling and reporting in the CM ObjectParser.
Specifically:
1. ObjectIDs used as array indexes are checked for being out of bounds,
and if so an error message is printed before the assert.
2. An error message is printed for unsupported NameSpaceIDs.
3. Adds support for unimplemented parsers by allowing IDs to list a
NULL parser, resulting in an unimplemented message being printed.

This fixes two bugs and adds some enhancements to the handling of
characters and strings in objects being printed by the CM ObjectParser.
Bug fixes:
1. PrintOemID() currently attempts to print characters with "%C",
but the correct syntax is (lowercase) "%c". This bug results in
"CCCCCC" being printed instead of the actual ASCII characters.
2. PrintString() is being passed a pointer to data in objects, but in
some cases this data is the actual string to print and other cases
it is a pointer to the string to print. This adds a PrintStringPtr
function and uses the correct functions depending on the situation.
Enhancements:
1. Some objects contain ASCII characters, which are currently printed
as their hex values. This adds functions to print out ASCII
character fields as text rather than hex, and uses those functions in
several cases where the object data is defined to be ASCII.
2. The PrintOemID() function is replaced with the new identical but more
generecically-named PrintChar6() function.

Referring to a file relative to a regular file makes no sense (or at least
it cannot be implemented consistently with how a file is referred to
relative to a directory). VirtioFsSimpleFileOpen() has enforced this
strictly since the beginning, and a few months ago I reported USWG Mantis
ticket #2367 [1] too, for clearing up the related confusion in the UEFI
spec.
Unfortunately, the shim boot loader contains such a bug [2] [3]. I don't
believe the shim bug is ever going to be fixed. We can however relax the
check in VirtioFsSimpleFileOpen() a bit: if the pathname that's being
opened relative to a regular file is absolute, then the base file is going
to be ignored anyway, so we can let the caller's bug slide. This happens
to make shim work.
Why this matters: UEFI-bootable Linux installer ISOs tend to come with
shim and grub in the embedded (ElTorito) FAT image (ESP). Sometimes you
want to build upstream shim/grub binaries, but boot the same ISO
otherwise. The fastest way for overriding the ESP for this purpose is to
copy its original contents to a virtio filesystem, then overwrite the shim
and grub binaries from the host side. Note that this is different from
direct-booting a kernel (via fw_cfg); the point is to check whether the
just-built shim and grub are able to boot the rest of the ISO.

PcatRealTimeClockRuntimeDxe seems to have copied the interface name
LibRtcVirtualNotifyEvent() from EmbeddedPkg's RealTimeClockLib class.
That's not right, for two reasons:
- PcatRealTimeClockRuntimeDxe doesn't consume "EmbeddedPkg.dec" in the
first place,
- in EmbeddedPkg, the RealTimeClockLib class API
LibRtcVirtualNotifyEvent() is about to be eliminated (it's a bogus API).
Rename the LibRtcVirtualNotifyEvent() function to VirtualNotifyEvent(),

This patch fixes wrong condition because of UINT16 value to integer
promotion. NumberMcFilters is UINT16 value, so when bitwise shift operator
applied to small integer type, the operation is preceded by integral
promotion. This is described in MISRA-C:2004 guideline as Rule 10.5:
"If the bitwise operators ~ and << are applied to an operand of underlying
type unsigned char or unsigned short, the result shall be immediately cast
to the underlying type of the operand."
A simple fix for this issue would be the following:
if ((UINT16)(UsbEthFunDescriptor.NumberMcFilters << 1) == 0)
But this patch proposes to use bitwise AND operation with a proper bit mask
rather than shifting to prevent similar mistakes in future.

Old implementation of RefreshMemoryAttributesFromMtrr directly
retrieves the MTRR register content and applies the MTRR cache type
to GCD database following the precedence order defined by SDM.
The code can updated to simply get all the memory cache types for all
memory through newly introduced API With the new introduced API
MtrrGetMemoryAttributesInMtrrSettings.
Benefits:
1. Remove the duplicated logic in CpuDxe driver that handles MTRR
details.
2. Let the MtrrLib to handle the case when fixed MTRR is absent.
(Old logic cannot handle the case.)

Update APIs related to set memory attributes to handle the fixed MTRR
is not always supported.
There are 3 APIs in MtrrLib that can set memory attributes:
1. MtrrSetMemoryAttributesInMtrrSettings
2. MtrrSetMemoryAttributeInMtrrSettings
3. MtrrSetMemoryAttribute
The general idea applied in MtrrSetMemoryAttributesInMtrrSettings is:
1. MtrrLibPreMtrrChange saves the old MTRR default type which
contains bit to enable fixed MTRR.
2. Main logic in MtrrSetMemoryAttributesInMtrrSettings applies
memory attribute settings for below 1MB to variable MTRRs
if fixed MTRR is not supported.
3. MtrrLibPostMtrrChange unconditionally sets E bit in MTRR default
type MSR but only set FE bit when fixed MTRRs are modified.

Trying to configure the TLS ciphers can lead to TLS handshake failures
because TlsCipherMappingTable is not in line with the ciphers actually
supported by OpensslLib.
Fix that by removing TlsCipherMappingTable altogether. Use
SSL_get_ciphers() instead to get the stack of ciphers supported by
openssl. Name and ID of the ciphers can be queried using the
SSL_CIPHER_get_name() and SSL_CIPHER_get_protocol_id() functions,
which allows us to map IDs to names without a hard-code table.
