tor-resolve asserts due to missing crypto initialization.

From IRC, trivial to reproduce.

I reproduced it with master, but any version that uses the siphash backed HT implementation will have this problem. Calling crypto_global_init() and linking the appropriate libraries fixes the problem, naturally.

To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
