Pieter Wuille b5c9ee756f Make test_point_times_order test meaningful again 
As wnaf splitting is scalar based, multiplying with the order directly
would be reduced to multiplication with zero before even converting to
wnaf.

Wno-unused-function is used for the moment because of the checking
 functions which are currently only used by VERIFY but are not (yet?)
 ifdefed out in normal builds.

8563713 Add non-null and unused-result warnings for the external API. (Gregory Maxwell)

Gregory Maxwell 8563713a4f Add non-null and unused-result warnings for the external API. 
GCC (and clang) supports extensions to annotate functions so that their
 results must be used and so that their arguments can't be statically
 provable to be null. If a caller violates these requirements they
 get a warning, so this helps them write correct code.

I deployed this in libopus a couple years ago with good success, and
 the implementation here is basically copied straight from that.

One consideration is that the non-null annotation teaches the optimizer
 and will actually compile out runtime non-nullness checks as dead-code.
 Since this is usually not whats wanted, the non-null annotations are
 disabled when compiling the library itself.

The commit also removes some dead inclusions of assert.h and introduces
 compatibility macros for restrict and inline in preparation for some
 portability improvements.
