This fixes security=domain, which has been broke since the big charset

Browse Source 
changeover.  For my own sainity I have created a new function to fill out both
the header and buffer for a string in an RPC struct.  This DOES NOT take a
length argument, only the actual string to be placed.

The RPC code is currently littered with code that does init_uni_hdr() followed
immidiatly by init_unistr2(), and often the length argument is wrong.  (It was
for the code I changed, even before the charset stuff).  Another bug where we
made strings AT LEAST MAX_UNICODE_LEN long hid this bug.

This works for loopback connections to Samba, and can't be any more broke than
it was before :-).  (We had double and revese conversions, fun...).

In particular this makes us multibyte complient.

In any case, if there are no objections I will slowly convert other bits of
code to the same system.
