OK, it appears this uses some internal openssl classes for bignum, and is copied directly from a Bitcoin source distribution. In OpenSSL 1.1.x, bignum is no longer exposed in the headers, so we need to replace the implementation without referring to bignum internals.

Since base58 is small, self-contained and doesn't really need the full functionality of bignums, a better approach is to rewrite the code using a different approach. Fortunately, we can simply use MIT licensed code from Bitcoin.

So solving this issue essentially involves porting this commit from Bitcoin to FC. (Strange coincidence: The commit hash for this base58 related commit starts with b58!)

Looks like openssl reorganized their headers and is just some missing #include. Investigating.
