Implement full multiplication `UInt<A> * UInt<B> -> UInt<A + B>` and
`quick_mul_hi` that returns the higher half of the product `UInt<A> * UInt<A>`.
These 2 functions will be used for dyadic floating point class.

Summary:
A previous change removed a transient inclusion of `stdlib.h` from the
`string_utils.h` file which this test depended on. Include it directly
here.
This patch adds scanf, sscanf, and fscanf entrypoints. It also adds unit
tests for sscanf and a basic test to fscanf. The scanf function is
basically impossible to test in an automated fashion due to it recieving
user input.

The mprotect test has been failing and causing significant buildbot
noise. Given that this is a simple functions it's more important that
the buildbot errors be useful than having more thorough tests for this
function.

Implement gettimeofday per
.../onlinepubs/9699919799/functions/gettimeofday.html.
This call clock_gettime to implement gettimeofday function.
Tested:
Limited unit test: This makes a call and checks that no error was
returned. Used nanosleep for 100 microseconds and verfified it
returns a value that elapses more than 100 microseconds and less
than 300 microseconds.

In the code
const char *str = "abc"
if you do sizeof(str) you get the size of the pointer, not the string.
This patch fixes that mistake.

This patch adds the basic conversion facilities to scanf as well as unit
tests for them. It also adds scanf_main which will be used for the
eventual scanf entrypoints.

This is the interface that will be used to read from a file or string in
scanf. This patch also adds the string and file implementations of the
reader, although the file reader is not yet complete since ungetc has
not yet been implemented.

Previously, the printf parser would treat "%\0" as a conversion with the
name "\0", and advance past the null byte causing a buffer overflow.
This patch corrects that in both printf and scanf.

This patch extracts the testing logic from `op_tests.cpp` into
`memory_check_utils.h` so we can reuse it for mem* function integration
tests.
This makes testing consistent and thorough.
For instance this catches a bug that got unnoticed during submission of
D136595 and D135134. Integration test for memcmp was only testing a
single size.
This also leverages ASAN to make sure that data is not read / written
outside permitted boundaries

The strcoll function is intended to compare strings based on their
ordering in the current locale. Since the locale facilities have not yet
been added, a simple implementation that is the same as strcmp has been
added as a placeholder.

This is the first piece of scanf. It's very similar in design to printf,
and so much of the code is copied from that. There were potential issues
with conflicting macros so I've also renamed the "ASSERT_FORMAT_EQ"
macro for printf to "ASSERT_PFORMAT_EQ".

This version is more composable and also simpler at the expense of being more explicit and more verbose.
This patch provides rationale for the framework, implementation and unit tests but the functions themselves are still using the previous version. The change in implementation will come in a follow up patch.
