Whack attribute code with a club until it works with PKCS #11.
PKCS #11 supports zero-length attributes (eg, CKA_LABEL) so hack of using zero length attribute as NIL value won't work, instead we use a slightly more portable version of the hack PKCS #11 uses (PKCS #11 stuffs -1 into a CK_ULONG, we stuff 0xFFFFFFFF into a uint32_t). ks_attribute.c code was trying too hard and tripping over its own socks. Instead of trying to maintain attributes[] in place during modification, we now perform the minimum necessary change then re-scan the block. This is (very slightly) slower but more robust, both because the scan code has better error checking and because it's the scan code that we want to be sure is happy before committing a change. Rename hal_rpc_pkey_attribute_t to hal_pkey_attribute_t.
