Run a connected line interception subroutine and update a channel's connected line information.
Whenever we want to update a channel's connected line information, we may need to run a subroutine so that an administrator can manipulate the information before sending it out. This function both runs the subroutine specified by CONNECTED_LINE_SEND_SUB and sends the update to the channel.

| char * | agent_type, | ||
| size_t | size | ||
| ) |
Find the appropriate CC agent type to use given a channel.
During call completion, we will need to create a call completion agent structure. To figure out the type of agent to construct, we need to ask the channel driver for the appropriate type.
Prior to adding this function, the call completion core attempted to figure this out for itself by stripping the technology off the channel's name. However, in the case of chan_dahdi, there are multiple agent types registered, and so simply searching for an agent type called "DAHDI" is not possible. In a case where multiple agent types are defined, the channel driver must have a queryoption callback defined in its channel_tech, and the queryoption callback must handle AST_OPTION_CC_AGENT_TYPE
If a channel driver does not have a queryoption callback or if the queryoption callback does not handle AST_OPTION_CC_AGENT_TYPE, then the old behavior of using the technology portion of the channel name is used instead. This is perfectly suitable for channel drivers whose channel technologies are a one-to-one match with the agent types defined within.
Note that this function is only called when the agent policy on a given channel is set to "native." Generic agents' type can be determined automatically by the core.

Get a device name given its channel structure.
A common practice in Asterisk is to determine the device being talked to by dissecting the channel name. For certain channel types, this is not accurate. For instance, an ISDN channel is named based on what B channel is used, not the device being communicated with.
This function interfaces with a channel tech's queryoption callback to retrieve the name of the device being communicated with. If the channel does not implement this specific option, then the traditional method of using the channel name is used instead.

Mutex that prevents multiple ast_channel_move() operations from occurring simultaneously. This is necessary since the involved channels have to be locked and unlocked throughout the move operation.
The most important data being protected are the masq and masqr data on channels. We don't want them getting criss-crossed due to multiple moves mucking with them.
