to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

On error, mallopt is supposed to return 0, not -1.

Summary:
The C interceptors were using `SIZE_T` defined in the interception library as
a `__sanitizer::uptr`. On some 32-bit platforms, this lead to the following
warning:
```
warning: declaration of ‘void* malloc(SIZE_T)’ conflicts with built-in declaration ‘void* malloc(unsigned int)’ [-Wbuiltin-declaration-mismatch]
INTERCEPTOR_ATTRIBUTE void *malloc(SIZE_T size) {
```
`__sanitizer::uptr` is indeed defined as an `unsigned long` on those.
So just include `stddef.h` and use `size_t` instead.

Summary:
This CL adds support for aligned new/delete operators (C++17). Currently we
do not support alignment inconsistency detection on deallocation, as this
requires a header change, but the APIs are introduced and are functional.
Add a smoke test for the aligned version of the operators.

Summary:
This is a follow-up to D42506.
There are a few of things that bothered me about `scudo_interceptors.cpp`:
- the filename is a misnomer: it intercepts some functions, but the rest (C++)
is actually in `scudo_new_delete.cpp`. I feel like `scudo_malloc.cpp` is more
appropriate (ASan uses the same naming scheme);
- we do not need "full" interceptors, since we are never accessing the
unsanitized version of the functions, we just need the
`extern "C" INTERCEPTOR_ATTRIBUTE` part of it to just call our functions;
- a couple of functions where duplicated while they could just be `ALIAS`'d;
- use the `SANITIZER_INTERCEPT_*` defines to hide the unneeded interceptors;
- use `SIZE_T` instead of `uptr`: while it's the same behind the curtain,
the former is meant for this use case.
In the end there is no functional change on the currently supported platforms
(Linux, Android).
