Gregory Maxwell 71712b27e5 Switch to C89 comments in prep for making the whole codebase C89 compatible.
This should be whitespace/comment only changes and should produce the same
object code.

Peter Dettman 5dd421bab5 Rewrite mul/sqr for 32bit/64bit
- interleave calculation of the lower and upper partial product ranges, and reduction
- less registers needed, more opportunities for parallel ops

Gregory Maxwell a099073a7e Enable warnings.
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.

Gregory Maxwell 9974d8693e Misc. Warning and cosmetic error cleanups.
This fixes a cosmetic precedence bug in the tests along with some
 type warnings.

It also adds a dummy cast to the CHECK macro to avoid hundreds
 of statement with no effect warnings on compilers that warn about
 such things.

Magnitude m means values are allowed to be up to 2 * 0xFFF...FFF * m,
while the argument passed to secp256k1_fe_negate didn't take the 2 into
account. Fix this.
