Add ECDH module which works by hashing the output of ecmult_const

Add constant-time multiply secp256k1_ecmult_const for ECDH
...
Designed with clear separation of the wNAF conversion, precomputation
and exponentiation (since the precomp at least we will probably want
to separate in the API for users who reuse points a lot.
Future work:
- actually separate precomp in the API
- do multiexp rather than single exponentiation

Fix build with static ecmult altroot and make dist.
...
Gen_context was unable to find the required headers without some
autotools fixups. Make dist was also broken without the extra
sources for the host side table builder utility.

Add ability to use a statically generated ecmult context.
...
This vastly shrinks the size of the context required for signing on devices with
memory-mapped Flash.
Tables are generated by the new gen_context tool into a header.
