That's pure string tokenizer -- find the separator in the buffer and
advance to next token.

The param transformation is using the parser for SIP header/URI
parameters, where comma is not a separator for parameters, but for
header/uri bodies.

I think it may work with some workaround done in pv module -- iirc, the
pv module is cloning the value in a local buffer, so then it can replace
the comma separator with another one (set by modparam or so) in the
local buffer, so it doesn't impact the original value and it doesn't
require to change the sip param parser.
