Subject: Add the strlen to push to smb_bytes_push_str, return the converted size
X-Git-Url: http://git.samba.org/?p=metze%2Fsamba%2Fwip.git;a=commitdiff_plain;h=37da26a06ee0a51f2e6c7b93e2fefc2342613c84

Add the strlen to push to smb_bytes_push_str, return the converted size

The pushed strlen replaces the STR_TERMINATE flag which I personally always
find very confusing.
