Optimize ScalarBaseMult Code uses a windowing/precomputing strategy to minimize ECC math. Every 8-bit window of the 256 bits that compose a possible scalar multiple has a complete map that's pre-computed. The precomputed data is in secp256k1.go and the generator for that file is in gensecp256k1.go Also fixed a spelling error in a benchmark test. Results so far seem to indicate the time taken is about 35% of what it was before. Closes #2 2014-09-24 19:41:07 +02:00			`// Copyright (c) 2014 Conformal Systems LLC.`

Rework the pre-computed table generation and load. This commit reworks the way that the pre-computed table which is used to accelerate scalar base multiple is generated and loaded to make use of the go generate infrastructure and greatly reduce the memory needed to compile as well as speed up the compile. Previously, the table was being generated using the in-memory representation directly written into the file. Since the table has a very large number of entries, the Go compiler was taking up to nearly 1GB to compile. It also took a comparatively long period of time to compile. Instead, this commit modifies the generated table to be a serialized, compressed, and base64-encoded byte slice. At init time, this process is reversed to create the in-memory representation. This approach provides fast compile times with much lower memory needed to compile (16MB versus 1GB). In addition, the init time cost is extremely low, especially as compared to computing the entire table. Finally, the automatic generation wasn't really automatic. It is now fully automatic with 'go generate'. 2015-02-01 08:55:16 +01:00			`// Auto-generated file (see genprecomps.go)`
