[PATCH] fix build with --disable-crypto

options.c is missing the definition for struct context when built with
--disable-crypto, as it then doesn't get pulled in through push.h,
leading to build errors like:

options.c: In function ‘parse_http_proxy_fallback’:
options.c:1474: error: dereferencing pointer to incomplete type
options.c:1477: error: dereferencing pointer to incomplete type
options.c:1478: error: dereferencing pointer to incomplete type

Fix it by including forward.h
