b110c106fa Change exhaustive test groups so they have a point with X=1 
This enables testing overflow is correctly encoded in the recid, and
likely triggers more edge cases.

Also introduce a Sage script to generate the parameters.

cd473e02c3 Avoid calling secp256k1_*_is_zero when secp256k1_*_set_b32 fails. 
Most of the codebase correctly used short-cutting to avoid calling
 _is_zero on possibly incompletely initialized elements, but a few
 places were missed.

abe2d3e84b Fix header guards using reserved identifiers 
Identifiers starting with an underscore and followed immediately by a capital letter are reserved by the C++ standard.

The only header guards not fixed are those in the headers auto-generated from java.

37697832d6 Restructure nonce clearing 
Make sure we clear the nonce data even if the nonce function fails (it may have written partial data), and call memset only once in the case we iterate to produce a valid signature.

3bb9c44719 Rewrite ECDSA signature parsing code 
There are now 2 encoding formats supported: 64-byte "compact" and DER.
The latter is strict: the data has to be exact DER, though the values
inside don't need to be valid.

213aa67397 Do not force benchmarks to be statically linked. 
Libtool will do the right thing and use whatever is available
 based on --enable-shared/--enable-static.

This also means that some of the things we build actually
 test the dynamic library.

cfe0ed916a Fix miscellaneous style nits that irritate overactive static analysis. 
Also increase consistency with how overflow && zero is tested, and
 avoid some mixed declarations and code that GCC wasn't detecting.
