* unoptimized msm * MSM: reorder loops * add a signed windowed recoding technique * improve wNAF table access * use batchAffine * revamp EC tests * MSM signed digit support * refactor MSM: recode signed ahead of time * missing test vector * refactor allocs and Alloca sideeffect * add an endomorphism threshold * Add Jacobian extended coordinates * refactor recodings, prepare for parallelizable on-the-fly signed recoding * recoding changes, introduce proper NAF for pairings * more pairings refactoring, introduce miller accumulator for EVM * some optim to the addchain miller loop * start optimizing multi-pairing * finish multi-miller loop refactoring * minor tuning * MSM: signed encoding suitable for parallelism (no precompute) * cleanup signed window encoding * add prefetching * add metering * properly init result to infinity * comment on prefetching * introduce vartime inversion for batch additions * fix JacExt infinity conversion * add batchAffine for MSM, though slower than JacExtended at the moment * add a batch affine scheduler for MSM * Add Multi-Scalar-Multiplication endomorphism acceleration * some tuning * signed integer fixes + 32-bit + tuning * Some more tuning * common msm bench + don't use affine for c < 9 * nit
