[SR-Users] Textops and Multipart Body - adding ISUP

[Daniel-Constantin Mierla]

CC-ed Victor -- iirc, he was the author of the functions for multi-part
body -- maybe he remembers the rules for these function, if they take
0x0 as terminator or not.

>From what I remember by heart, a normal body should work fine with
non-printable characters -- there is easy to check if the content-length
includes them or not.

Cheers,
Daniel
