Without this patch we will get following error:
```
SSL: couldn't create a context: error:00000000:lib(0):func(0):reason(0)
```
during trying to connect HTTPS.
1. libcurl.mk now changed to build against static openssl from deps.
2. but, it won't work with openssl 1.1.1a, bcz of SSL: couldn't create a context: error:00000000:lib(0):func(0):reason(0) ,
so, in test i decided to upgrade openssl to 1.1.1b.
3. original openssl.mk was with many disabled features, i enable all of them,
of course it's don't needed and we need to leave only SSL/TLS things enabled
in OpenSSL build.
4. probably i broke something in Windows and MacOS build.
This commit is only first approach to continue work.
The only upstream change relative to the previous commit is that the
various Zcash-specific dependencies have been pulled into a cargo
workspace. The dependecies in the workspace use the same commits as the
crates we had previously vendored.
The patches are necessary to handle the fact that cargo requires that
dev dependencies are available even if not used, and we would otherwise
need to vendor all the underlying crates.
