Jian J Wang c44218e5f4 MdeModulePkg/Core: Fix heap guard issues
Three issues addressed here:

a. Make NX memory protection and heap guard to be compatible
The solution is to check PcdDxeNxMemoryProtectionPolicy in Heap Guard to
see if the free memory should be set to NX, and set the Guard page to NX
before it's freed back to memory pool. This can solve the issue which NX
setting would be overwritten by Heap Guard feature in certain
configuration.

b. Returned pool address was not 8-byte aligned sometimes
This happened only when BIT7 is not set in PcdHeapGuardPropertyMask. Since
8-byte alignment is UEFI spec required, letting allocated pool adjacent to
tail guard page cannot be guaranteed.

c. NULL address handling due to allocation failure
When allocation failure, normally a NULL will be returned. But Heap Guard
code will still try to adjust the starting address of it, which will cause
a non-NULL pointer returned.

Liming Gao 7c73626513 MdeModulePkg: Update PCD driver to support the optimized PcdDataBase
https://bugzilla.tianocore.org/show_bug.cgi?id=546
BaseTools will generate the optimized PCD database to save the image size
at build time for multiple SKUs. The optimized PCD database layout will be like
below, the PCD database will be composed of the full default SKU data
(PCD_DATABASE_INIT) and the non-default SKU delta data(PCD_DATABASE_SKU_DELTA).
PCD driver will build HOB to store the full default SKU data, and patch HOB
data based on non-default SKU delta data for the SKU set by SetSku(),
it can save memory resource at boot time.

//
// PCD database layout:
// +---------------------------------+
// | PCD_DATABASE_INIT (DEFAULT SKU) |
// +---------------------------------+
// | PCD_DATABASE_SKU_DELTA (SKU A)  |
// +---------------------------------+
// | PCD_DATABASE_SKU_DELTA (SKU B)  |
// +---------------------------------+
// | ......                          |
// +---------------------------------+
//

BaseTools, PCD database and driver updates are needed for this proposal.
For single SKU (default) case, this proposal is expected to have no impact.
For multi-SKU case, PCD database format will be changed.
So, PcdDataBase Version is also updated from 6 to 7.

function, and then call Ip4Output. However, if Ip4Output gets some
error and exits early, e.g. fails to find the route entry, memory
buffer of "Data" gets no chance to be freed and memory leak will be
caused. If there is such an attacker in the network, we will see UEFI
runs out of memory and system hangs.

So we explicitly free the memory when error status is returned.

Jian J Wang 2ac1730bf2 MdeModulePkg/DxeIpl: Mark page table as read-only
This patch will set the memory pages used for page table as read-only
memory after the paging is setup. CR0.WP must set to let it take into
effect.

A simple page table memory management mechanism, page table pool concept,
is introduced to simplify the page table memory allocation and protection.
It will also help to reduce the potential recursive "split" action during
updating memory paging attributes.

The basic idea is to allocate a bunch of continuous pages of memory in
advance as one or more page table pools, and all future page tables
consumption will happen in those pool instead of system memory. If the page
pool is reserved at the boundary of 2MB page and with same size of 2MB page,
there's no page granularity "split" operation will be needed, because the
memory of new page tables (if needed) will be usually in the same page as
target page table you're working on.

And since we have centralized page tables (a few 2MB pages), it's easier
to protect them by changing their attributes to be read-only once and for
all. There's no need to apply the protection for new page tables any more
as long as the pool has free pages available.

Once current page table pool has been used up, one can allocate another 2MB
memory pool and just set this new 2MB memory block to be read-only instead of
setting the new page tables one page by one page.

Two new PCDs PcdPageTablePoolUnitSize and PcdPageTablePoolAlignment are used
to specify the size and alignment for page table pool. For IA32 processor
0x200000 (2MB) is the only choice for both of them to meet the requirement of
page table pool.

Laszlo (lersek@redhat.com) did a regression test on QEMU virtual platform with
one middle version of this series patch. The details can be found at

 https://lists.01.org/pipermail/edk2-devel/2017-December/018625.html

There're a few changes after his work.
