* The RFC doesn't limit the context to be a string.
It talks about `octets` which means it could be any binary data.
* Move the context-preprocessing function out of tweetnacl.c
* Fix potential segfaults when Ed25519 signature verification fails and
`LTC_CLEAN_STACK` is enabled.
* Fix all the warnings.
* Update documentation.

Replace strcmp/memcmp with XSTRCMP/XMEMCMP for check-source
Fix for check-defines
XSTRCMP/XMEMCMP != 0
GCC7.3 wants only literal strings for sprintf format

Rework SSH decoding and tests
Fix encoding and tests
COMPARE_TESTVECTOR macro

Code review tweaks
Ensure it's not possible to read past buffer end
Keep track of size remaining, not end pointer
Optionally return recovery ID from ecc_sign_hash()
Update documentation
Update tests for ECC recovery
Fix (v,r,s) signature format, regenerate recovery test
Fix over-freeing of private key
Code review fixes to docs
Rename LTC_ECCSIG_BLOCKCHAIN to LTC_ECCSIG_ETH to reflect original definition
Rename to LTC_ECCSIG_ETH27 to make clear it's using the Ethereum +27 convention
Code review changes - calculate recovery ID only if needed, type safety on signature format enum
Use enum for sigformat in docs, and add explanatory note for recid<0
Range checks on v, check RFC7518 signatures' length based on size of key. Fix for when order>prime.
Limit LET_ECCSIG_ETH27 to secp256k1 curve only
Workaround for TFM missing sqrtmod_prime
Fix unused variable warnings with USE_TFM, make TomsFastMath a runtime check
Disable ecc_recover_key if no ecc_mul2add available
Wrap ecc_recover_key and its test in #ifdef LTC_ECC_SHAMIR
