The standard dictates that `std::size_t` is used, rather than the plain
`size_t` type.
Even though these types are usually, if not always, exactly the same
type, other code might assume that `std::size_t` is actually used and thus
also available under that name after including `<new>`.
This fixes that by using the right type. One challenge is that it is
usually declared in headers that we do not have available, so this just
defines the `std::size_t` type in the `<new>` header to work around
that.

This is currently disabled, keeping the old behavior of returning
NULL on failure, but should probably be enabled in the future as code
that does want to do a null check has had a chance to switch to the
more portable nothrow versions.
When enabled, allocation failure calls the weak `std::terminate()`,
which calls `abort()` by default, but can be replaced by user code to do
more specific handling.
To enable this, a macro must be defined (in new.cpp or on the compiler
commandline).
This fixes part of #287.

This makes this header complete up to including C++14, except two
exception classes that cannot be defined without `<exception>`.
The functions related to the "new_handler" are declared but not actually
defined, to prevent overhead and complexity. They are still declared to
allow implementing them in user code if needed.
This makes the implementation of all operator new and delete functions
comply with the C++11/C++14 specification in terms of which should be
actually implemented and which should be delegate to other functions.
There are still some areas where these implementations are not entirely
standards-compliant, which will be fixed in subsequent commits.
This fixes part of #287 and fixes #47.

The standard mandates that placement new should be have a noexcept specifier.

Casting to void is a well known trick for prevening 'unused parameter' warnings.

The following empty stubs has been replaced by the gcc
flag -fno-threadsafe-static:
int __cxa_guard_acquire(__guard *);
void __cxa_guard_release (__guard *);
void __cxa_guard_abort (__guard *);
The following empty stubs has been moved into their specific
module abi.cpp:
void __cxa_pure_virtual(void) __attribute ((noreturn));
void __cxa_deleted_virtual(void) __attribute ((noreturn));
