Tobin Harding bfd88dbd6c Move WASM const definitions to a source file
Currently we are defining the WASM integer size and alignments in the
`stdio.h` header file, this is wrong because this file is included in
the build by way of `build.rs` as well as by upstream `libsecp256k1`.

Move WASM integer definitions to a `C` source file and build the file
into the binary if target is WASM.

Andrew Poelstra 8294ea3f50 secp256k1-sys: update upstream library
Two API changes needed to be reflected: schnorrsig_sign and schnorrsig_verify.

Also bump both Cargo.toml files

Matt Corallo ee1103a1f3 Reduce visibility on secp-sys symbols
cc-rs builds C dependencies with reduced visibility to avoid
exporting the C symbols all the way out to any rust-built shared
libraries however we override it with SECP256K1_API. We should
avoid doing this, allowing LTO/DCE to do its work.

Andrew Poelstra d77483f00e replace cargo `external-symbols` feature with a rustc --cfg flag
This feature was not useful for Cargo users, since Cargo does not give you
the kind of fine-grained control over C library linkage that you need. So
it was just unnecessarily confusing and would cause the build to break if
you enabled it accidentally, say, with --all-features.

Andrew Poelstra 1a9aece312 secp256k1-sys: update upstream to 670cdd3f8be25f81472b2d16dcd228b0d24a5c45 2020-08-26 18:07:41 +00:00
Tim Ruffing 489e3ff8d2
Define ECMULT_GEN_PREC_BITS
This is configurable in upstream now.

Fixes #214.

So far, this just sets it to `4`. It's tempting to set it to `2` when `lowmemory` is enabled
but `lowmemory` is about RAM and not about binary size. This is better addressed by
a resolution of #193.

Matt Corallo d9d398ccc9 Re-support WASM via simple stub headers
libsecp256k1 really only barely uses libc at all, and in practice,
things like memcpy/memcmp get optimized into something other than a
libc call. Thus, if we provide simple stub headers, things seem to
work with wasm-pack just fine.

Add external-symbols feature to support external libsecp
This feature disables using the bundles sources and will link into
existing libsecp256k1 symbols.
