spandsp: fixing t38 with configurable tone type.
- tone_type value is taken from dialplan
t38_gateway function's 2nd parameter
- tone type could be one of
cng|ced_preamble|ans|ans_pr|ansam|preamble
- in dialplan, if enable t38 in ftdm-to-sip,
tone type should be set to "t38_gateway peer cng"
- if enable t38 in sip-to-ftdm,
tone type should be set to "t38_gateway peer ced_preamble"
