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 2.4. Added sequence number limits. Added
struct opie_otpkey and made many functions use it. Added
opiestrncpy(). Include header with libmissing prototypes.
Modified by cmetz for OPIE 2.32. Added symbolic flag names for
opiepasswd(). Added __opieparsechallenge() prototype.
Modified by cmetz for OPIE 2.31. Removed active attack protection.
Modified by cmetz for OPIE 2.3. Renamed PTR to VOIDPTR. Added
re-init key and extension file fields to struct opie. Added
opie_ prefix on struct opie members. Added opie_flags field
and definitions. Added more prototypes. Changed opiehash()
prototype.
Modified by cmetz for OPIE 2.22. Define __P correctly if this file
is included in a third-party program.
Modified by cmetz for OPIE 2.2. Re-did prototypes. Added FUNCTION
definition et al. Multiple-include protection. Added struct
utsname fake. Got rid of gethostname() cruft. Moved UINT4
here. Provide for *seek whence values. Move MDx context here
and unify. Re-did prototypes.
Modified at NRL for OPIE 2.0.
Written at Bellcore for the S/Key Version 1 software distribution
(skey.h).
