lib,lib-index: Use #ifdef with WORDS_BIGENDIAN Some were missing from the last change.

global: Use #ifdef instead of #if with WORDS_BIGENDIAN This is to not rely on undefined WORDS_BIGENDIAN being evaluated as 0.

lib: Mark md4/md5/sha1/sha2 code with ATTR_UNSIGNED_WRAPS

[LEN] to [static LEN] on some function parameters Also add STATIC_ARRAY macro to hide it in c++ compilation.

liblib: Added a common API for accessing all hash methods.

Try to use (Apple) gcc's __BIG_ENDIAN__ and __LITTLE_ENDIAN__ macros if possible. Based on a patch by Apple. --HG-- branch : HEAD

Removed _ prefixes from function names. --HG-- branch : HEAD

Bad endianess fix. It required that LITTLE_ENDIAN and BIG_ENDIAN were already defined. Rather use WORDS_BIGENDIAN which configure already sets. --HG-- branch : HEAD

Define I_BYTE_ORDER macro ourself because BYTE_ORDER can't seem to be relied on. Fixes SHA1 giving wrong checksums at least in Solaris/sparc. --HG-- branch : HEAD

Change src from unsigned char* toi void* so callers don't have to do casting always. --HG-- branch : HEAD

Changed to use standard uint* types rather than u_int*. Also removed K&R-isms. --HG-- branch : HEAD

Forgot from last dovecotpw commit. --HG-- branch : HEAD
