r9339: treat arrays of uint8 values as a special DATA_BLOB type in the ejs

interfaces to RPC. This makes large blobs of data much saner. Tim, you
will probably want to do the same for the smb_interfaces.h generated
code.

Next we will need ways of extracting different data types from these
blobs, for example asking for the blob to be interpreted as a utf16
string, or as a little-endian integer. That will allow for registry
scripting to be quite sane.
(This used to be commit a8bca2e8e27c953c0413693326ec3b5ecf17ba41)
