build: Use own variable SECP_CFLAGS instead of touching user CFLAGS Fixes one of the items in #923, namely the warnings of the form '_putenv' redeclared without dllimport attribute: previous dllimport ignored [-Wattributes] This also cleans up the way we add CFLAGS, in particular flags enabling warnings. Now we perform some more fine-grained checking for flag support, which is not strictly necessary but the changes also help to document autoconf.ac.

Adds a declassify operation to aid constant-time analysis. ECDSA signing has a retry loop for the exceptionally unlikely case that S==0. S is not a secret at this point and this case is so rare that it will never be observed but branching on it will trip up tools analysing if the code is constant time with respect to secrets. Derandomized ECDSA can also loop on k being zero or overflowing, and while k is a secret these cases are too rare (1:2^255) to ever observe and are also of no concern. This adds a function for marking memory as no-longer-secret and sets it up for use with the valgrind memcheck constant-time test.

Add exhaustive test for group functions on a low-order subgroup We observe that when changing the b-value in the elliptic curve formula `y^2 = x^3 + ax + b`, the group law is unchanged. Therefore our functions for secp256k1 will be correct if and only if they are correct when applied to the curve defined by `y^2 = x^3 + 4` defined over the same field. This curve has a point P of order 199. This commit adds a test which computes the subgroup generated by P and exhaustively checks that addition of every pair of points gives the correct result. Unfortunately we cannot test const-time scalar multiplication by the same mechanism. The reason is that these ecmult functions both compute a wNAF representation of the scalar, and this representation is tied to the order of the group. Testing with the incomplete version of gej_add_ge (found in 5de4c5dff^) shows that this detects the incompleteness when adding P - 106P, which is exactly what we expected since 106 is a cube root of 1 mod 199.

Add ability to use a statically generated ecmult context. This vastly shrinks the size of the context required for signing on devices with memory-mapped Flash. Tables are generated by the new gen_context tool into a header.

build: don't use BUILT_SOURCES for the static context header BUILT_SOURCES simply forces the header to be built first. Use real dependencies instead. This fixes builds with dependency tracking disabled where a real target is specified. As a bonus, this also fixes the issue of gen_context and the header not being rebuilt when gen_context.c is touched.

Generate ecmult_static_pre_g.h This header contains a static array that replaces the ecmult_context pre_g and pre_g_128 tables. The gen_ecmult_static_pre_g program generates this header file.
