SHA2: Make slapd-sha2 module portable

Browse Source 
contrib/slapd-modules/passwd/sha2/sha2.[ch] need portable.h and
some macros to be portable source.

contrib/slapd-modules/passwd/sha2/slapd-sha2.c:hash_sha*() must
declare "struct berval digest" before a statement for K&R C,
and must replace C++ "// foo"-style comments with C style.
