George Kadianakis fe5a9db1e6 Disable ed25519-donna's batch verification. 
Fixes bug 40078.

As reported by hdevalence our batch verification logic can cause an assert
crash.

The assert happens because when the batch verification of ed25519-donna fails,
the code in `ed25519_checksig_batch()` falls back to doing a single
verification for each signature.

The crash occurs because batch verification failed, but then all signatures
individually verified just fine.

That's because batch verification and single verification use a different
equation which means that there are sigs that can pass single verification
but fail batch verification.

Fixing this would require modding ed25519-donna which is not in scope for
this ticket, and will be soon deprecated in favor of arti and
ed25519-dalek, so my branch instead removes batch verification.

README 

Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.

To build Tor from source:
        ./configure && make && make install

To build Tor from a just-cloned git repository:
        sh autogen.sh && ./configure && make && make install
