* util/sha1: add non-typedef name for the SHA1_CTX structEmil Velikov2017-03-152-1/+4
| | | | | | | | | | Using typedef(s) is not always the answer and makes it harder for people to do clever (or one might call nasty) things with the code. Add a struct name which we will use with follow-up commit. Signed-off-by: Emil Velikov <[email protected]> Reviewed-by: Grazvydas Ignotas <[email protected]>

* util: import sha1 implementation from OpenBSD17.0-branchpointEmil Velikov2017-01-183-0/+286
At the moment we support 5+ different implementations each with varying amount of bugs - from thread safely problems [1], to outright broken implementation(s) [2] In order to accommodate these we have 150+ lines of configure script and extra two configure toggles. Whist an actual implementation being ~200loc and our current compat wrapping ~250. Let's not forget that different people use different code paths, thus effectively makes it harder to test and debug since the default implementation is automatically detected. To minimise all these lovely experiences, import the "100% Public Domain" OpenBSD sha1 implementation. Clearly document any changes needed to get building correctly, since many/most of those can be upstreamed making future syncs easier. As an added bonus this will avoid all the 'fun' experiences trying to integrate it with the Android and SCons builds. v2: Manually expand __BEGIN_DECLS/__END_DECLS and document (Tapani). Furthermore it seems that some games (or surrounding runtime) static link against OpenSSL resulting in conflicts.
