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.

2b199de Use the explicit NULL macro for pointer comparisons. (Gregory Maxwell)

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.

2b199de888 Use the explicit NULL macro for pointer comparisons. 
This makes it more clear that a null check is intended. Avoiding the
 use of a pointer as a test condition alse increases the type-safety
 of the comparisons.

(This is also MISRA C 2012 rules 14.4 and 11.9)

Move all context checks to VERIFY_CHECK and be sure they come before all
ARG_CHECKs.
