commit 8e46bff8b88103f4a5b0d3920ab6e3901decaf22

s3:librpc/ndr: use new strlen_m_ext_term() in ndr_charset_length(): fix bug #7594
This fixes the calculation of needed space for destination unicode charset.
The last 4 patches address bug #7594 ("wbinfo -u" and "wbinfo -g" gives no
output (log=>ndr_pull_error)).
