Add powbatch, nPbatch, and multiscalar APIs
with various implementations for basic amd64, BMI, ADX, AVX2, and AVX-512,
plus portable implementations.
Include benchmarks on more microarchitectures. Add auto-generated table in documentation summarizing speeds, with OpenSSL speeds as a baseline for comparison.
For compatibility with musl etc.,
support constructor as an alternative to ifunc for dispatch.
Select constructor automatically if an ifunc compile-time test fails,
or if --notryifunc is passed to ./configure.
Add command-line interface for shell scripts.
Rely on separate libcpucycles
to automatically use RDPMC etc.,
and separate librandombytes
to automatically use getrandom etc.
Reorganize documentation into doc/*.md directory,
with auto-generation of HTML and manual pages.
Inside auto-generation of command/lib25519-test.c,
automatically cache Python computations of nP etc.
Reorganize precomputed tests to handle APIs with variable-length inputs and outputs.
Import infrastructure improvements from libmceliece.
