Batch inversions in Trust Tokens. The DLEQ and DLEQOR proofs require converting many Jacobian points to affine, some multiple times. The inversions involved can be batched. This buys us a +5-8% improvement in token issuance speed. issue and finish_issue should each only perform two inversions per token now. We could save an inversion per token by changing the dleq_generate and dleq_verify function signatures, but that would complicate the likely more valuable batched DLEQ(OR) optimization, so I've left those alone.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
