[PATCH] block-sha1: Windows declares ntohl() in winsock2.h

From: Johannes Sixt <redacted>

This is a minimal fix to compile block-sha1 on Windows. I did not do any
benchmarks whether the implementation of ntohl() is actually faster than
bytewise access and shifts.

 I would appreciate if our Windows experts could tell whether the
 implementation of ntohl/htonl is worth its money or whether we should
 go with the generic byte access plus shifts.
