When using builtin features like parking and transfers, the AST_FEATURE_* flags would not be set correctly for all instances when either performing a builtin attended transfer, or parking a call and getting the timeout callback.  Also, there was no way on a per-call basis to specify what features someone should have on picking up a parked call (since that doesn't involve the Dial() command).  There was a global option for setting whether or not all users who pickup a parked call should have AST_FEATURE_REDIRECT set, but nothing for DISCONNECT, AUTOMON, or PARKCALL.

This patch:
1) adds the BRIDGE_FEATURES dialplan variable which can be set either in the dialplan or with setvar in channels that support it.  This variable can be set to any combination of 't', 'k', 'w', and 'h' (case insensitive matching of the equivalent dial options), to set what features should be activated on this channel.  The patch moves the setting of the features datastores into the bridging code instead of app_dial to help facilitate this.

2) adds global options parkedcallparking, parkedcallhangup, and parkedcallrecording to be similar to the parkedcalltransfers option for globally setting features.

3) has builtin_atxfer call builtin_parkcall if being transfered to the parking extension since tracking everything through multiple masquerades, etc. is difficult and error-prone

4) attempts to fix all cases of return calls from parking and completed builtin transfers not having the correct permissions

I think I've tested the combinations of
A calls B, (A or B) (builtin or SIP) (blind or attended) transfers (B or A) to (C or parking)
and tested parking either timing out or being picked up.

The case I used was having tT in the Dials to the extensions with an optional k or K and tested the inheritance of the parking feature.

There are a lot of cases and it is certainly possible that I missed some, or typed the wrong extension and thought I was testing something that I wasn't, etc.  So I would *really* appreciate it if some other people could review this and test it out before committing.  Most of the stuff before hand was broken anyway, but still...
