Log:
chan_dahdi: Add inband_on_setup_ack compatibility option.
The new inband_on_setup_ack option causes Asterisk to assume inband audio
may be present when a SETUP_ACKNOWLEDGE message is received.
Q.931 Section 5.1.3 says that in scenarios with overlap dialing, when a
dialtone is sent from the network side, progress indicator 8 "Inband info
now available" MAY be sent to the CPE if no digits were received with the
SETUP. It is thus implied that the ie is mandatory if digits came with
the SETUP and dialtone is needed. This option should be enabled, when the
network sends dialtone and you want to hear it, but the network doesn't
send the progress indicator when needed.
NOTE: For Q.SIG setups this option should be enabled when outgoing overlap
dialing is also enabled because Q.SIG does not send the progress indicator
with the SETUP ACK.
The commit -r413714 (AST-1338) which causes this issue was dealing with a
SIP-to-ISDN interoperability issue.
This commit is a merge of the two patches indicated below.

===========================================================
+from 1.8.28.2 to 1.8.29.0:
+* Added the inband_on_setup_ack compatibility option to chan_dahdi.conf to
+ deal with switches that don't send an inband progress indication in the
+ SETUP ACKNOWLEDGE message.
+
from 1.8.28.0 to 1.8.28.1:
* Added http.conf session_inactivity timer option to close HTTP connections
that aren't doing anything.
