The BaseTools build feature introduced for TianoCore#1804 / in commit
1fa6699e6c ("BaseTools: Add a checking for Sources section in INF file",
2019-06-10) logs some (non-fatal) warnings about unlisted internal header
files. List those files explicitly.
Note: header files are added in lexicographical order only if the
underlying INF file already keeps the [Sources] and [LibraryClasses]
sections in lexicographical order. Otherwise, header files are added in
rough "logical" order.

Commit c51f8bae7c ("CryptoPkg: Fix possible build problem with
Clang") added -std=c99 to the CLANG38 compiler command line of
packages that incorporate parts of OpenSSL, to ensure that the new
C atomics code used by OpenSSL for refcounting (which we don't care
about) does not pull in system C library headers, which we cannot
rely on when (cross)building EDK2 code.
Unsurprisingly, CLANG35 (which is only defined for ARM and AARCH64)
suffers from the exact same issue, so let's add the same flags
there as well.

The malloc/free and AllocatePool/FreePool usages are required to be
matched, after extra memory size info header was introduced in malloc
wrapper.
This patch corrects two memory allocation cases, which requires the
caller to free the buffer with FreePool() outside the function call.
And some comments were also added to clarify the correct memory
release functions if it's the caller's responsibility to free the

For pointer subtraction, the result is of type "ptrdiff_t". According to
the C11 standard (Committee Draft - April 12, 2011):
"When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements. The
size of the result is implementation-defined, and its type (a signed
integer type) is ptrdiff_t defined in the <stddef.h> header. If the result
is not representable in an object of that type, the behavior is
undefined."
In our codes, there are cases that the pointer subtraction is not
performed by pointers to elements of the same array object. This might
lead to potential issues, since the behavior is undefined according to C11
standard.
Also, since the size of type "ptrdiff_t" is implementation-defined. Some
static code checkers may warn that the pointer subtraction might underflow
first and then being cast to a bigger size. For example:
UINT8 *Ptr1, *Ptr2;
UINTN PtrDiff;
...
PtrDiff = (UINTN) (Ptr1 - Ptr2);
The commit will refine the pointer subtraction expressions by casting each
pointer to UINTN first and then perform the subtraction:
PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2;
