Blobs are compared with ASCIIZ string comparison functions

[sjamaan]

#;1> (blob=? '#${1 2 3} '#${1 2 4})
#f
#;2> (blob=? '#${1 2 0 3} '#${1 2 0 4})
#t

The fix is most likely to use C_memcmp instead of C_strncmp since blob=? uses C_string_compare. I'm posting it in the bugtracker because we should really check all string functions (since strings in Scheme can contain NUL bytes too); there are many more cases where C functions are used (and for case-insensitive comparisons this is especially painful - we'd need to hand-code those since there are no C functions that deal with length-encoded strings; they all implicitly assume ASCIIZ)
