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 makes these functions weak, so that a sketch or library can replace
them. This does not apply to all of these operators, only for the ones
that the C++ standard specifies as replaceable.

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.

Originally, the Arduino core used "new.h", rather than the standard
"new", probably because the implementation was incomplete, and for the
most commonly used new and delete operators, no include is needed at all
(they are defined implicitly by the compiler). However, now Arduino
does expose the "new" name, as an alias for the older "new.h". Given
that the standard name is "new", it makes more sense to put the actual
content in "new", and make "new.h" a compatibility header that includes
"new" instead of the other way around.
