The ISO C standard says about realloc(),
If ptr is a null pointer, the realloc function behaves like the malloc
function for the specified size.
The realloc() implementation doesn't conform to this currently, so add a
check and call malloc() if appropriate.

The ISO C standard says about free(),
If ptr is a null pointer, no action occurs.
This is not true of the RuntimeFreeMem() internal function. Therefore we
must not forward the argument of free() to RuntimeFreeMem() without
checking.

The ISO C standard says about free(),
If ptr is a null pointer, no action occurs.
This is not true of the FreePool() interface of the MemoryAllocationLib
class:
Buffer must have been allocated on a previous call to the pool
allocation services of the Memory Allocation Library. [...] If Buffer
was not allocated with a pool allocation function in the Memory
Allocation Library, then ASSERT().
Therefore we must not forward the argument of free() to FreePool() without
checking.
This bug can be triggered by upstream OpenSSL commit 8e704858f219

Although the function qsort receives as an argument a "compare" function
which returns an "int", QuickSortWorker (the function used internally by
qsort to do its job) receives as an argument a "CompareFunction" which
returns an "INTN". In a 32-bit machine, "INTN" is defined as "INT32",
which is defined as "int" and everything works well. However, when qsort
is compiled for a 64-bit machine, "INTN" is defined as "INT64" and the
return values of the compare functions become incompatible ("int" for
qsort and "INT64" for QuickSortWorker), causing malfunction.
For example, let's assume qsort is being compiled for a 64-bit machine.
As stated before, the "compare" function will be returning an "int",
and "CompareFunction" will be returning an "INT64". When, for example,
the "compare" function (which was passed as an argument to qsort and,
then, re-passed as an argument to QuickSortWorker) returns -1 (or
0xffffffff, in a 32-bit integer, its original return type) from inside
a call to QuickSortWorker, its return value is interpreted as being an
"INT64" value - which turns out to be 4294967295 (or 0x00000000ffffffff,
in a 64-bit integer) -, making the function QuickSortWorker to behave
unexpectedly.
Note that this unexpected (or incorrect) conversion does not happen when
casting an "INT32" to an "INT64" directly, but does happen when casting
function types.
The issue is fixed by changing the return type of SORT_COMPARE (the type
of "CompareFunction", used by QuickSortWorker) from "INTN" to "int".
This way, both qsort and QuickSortWorker use compatible definitions for
their compare functions.

Make mVirtualAddressChangeEvent STATIC to prevent it from conflicting
with other variables of the same name that may be defined in other
libraries (e.g., MdeModulePkg/Universal/Variable/RuntimeDxe)
This also removes the risk of mVirtualAddressChangeEvent being merged with
other uninitialized variables with external linkage by toolchains that perform
COMMON allocation.

while MonthNo is the month of the year, so tm_mon should be MonthNo-1.
Similarly, tm_mday is the day of the month, and DayNo is the number
of days since the first day of the month. Assigning DayNo+1 to
tm_mday to fit the definition.
This commit also corrected miscalculated MonthNo and DayNo for the
first day of the month. (Thanks to Laszlo Ersek!)

Exit is declared to be 'noreturn' function, but GCC sees
that the empty function will return. Therefore, GCC flags
a warning.
To work-around this, we use a function pointer, along with
a cast to force the code to think that a 'noreturn' function
is being called.
