Sean Bruno 2f1e5d4767 Queisce two category of clang warnings:
1.  missing explicit includes for string.h, stdio.h, etc
2.  missing explicit declaration for some common functions

I have been unable to contact the upstream maintainer for this patch,
http://www.inner.net/opie appears to be the source of truth but it
unreachable

History:
Modified by cmetz for OPIE 2.32. Renamed mode to flags. Made flag
values symbolic constants. Added a flag for insecure override
support.
Modified by cmetz for OPIE 2.31. Removed active attack protection
support.
Modified by cmetz for OPIE 2.3. Split most of the function off
and turned this into a front-end for the new __opiewriterec().
Added code to compute the key from the secret. Use the opie_
prefix. Use new opieatob8() and opiebtoa8() return values.
Created by cmetz for OPIE 2.22.
