d371f21552 chan_dahdi: CLI "core stop gracefully" has needless delay for PRI and SS7.
The PRI and SS7 link control threads are not stopped correctly when the
chan_dahdi.so module is unloaded.  The link control threads pri_dchannel()
and ss7_linkset() are not awakened from a poll() to cancel the thread.

* Added a SIGURG signal after requesting the thread cancel to break the
link control thread poll() immediately.

For SS7 it was slightly worse, the link poll() timeout would always be
whatever was the last libss7 scheduled event time used.  If no libss7
scheduled event was pending, the thread could run more often than
necessary.

* Set nextms to 60 seconds for the ss7_linkset() poll() if there is no
other libss7 scheduled event.

6dbda720fc chan_dahdi/SS7: Made reject incoming call for an in-alarm or blocked channel.
If a SS7 call comes in requesting a CIC that is in-alarm, the call is
accepted and connects if the extension exists in the dialplan.  The call
does not have any audio.

* Made release the call immediately with circuit congestion cause.

43b66d3ef0 Made companding law for SS7 calls only determined by SS7 signaling type.
For SS7, the companding law for a call was chosen inconsistently depending
upon ss7type (ITU vs ANSI) and the DAHDI companding default (T1 vs E1).
For incoming calls, the companding law was determined by ss7type.  For
outgoing calls, the companding law was determined by the DAHDI default.
With the wrong combination you would get A-law/u-law conflicts.  An
A-law/u-law conflict sounds like bad static on the line.

SS7 ITU  signaling with E1 line: ok
SS7 ITU  signaling with T1 line: noise
SS7 ANSI signaling with E1 line: noise
SS7 ANSI signaling with T1 line: ok

* Fix the companding law used to be determined by the SS7 signaling type
only.

f83d1b98e8 Add support-level indications to many more source files.
Since we now have tools that scan through the source tree looking for files
with specific support levels, we need to ensure that every file that is
a component of a 'core' or 'extended' module (or the main Asterisk binary)
is explicitly marked with its support level. This patch adds support-level
indications to many more source files in tree, but avoids adding them to
third-party libraries that are included in the tree and to source files
that don't end up involved in Asterisk itself.

e0c235bd9b Setup DSP when SS7 call is connected or early media is available.
Outgoing SS7 calls fail to detect incoming DTMF so any bridged channel
that requires out-of-band DTMF will not work.

* Added sig_ss7_open_media() calls at appropriate places in sig_ss7.c.
The new call converts conditionaled out unconverted code and shows that
the code really did something useful.

* Improved some chan_dahdi DTMF debug messages to help track DTMF
handling.

7dc49195d8 Updated SIP 484 handling; added Incomplete control frame
When a SIP phone uses the dial application and receives a 484 Address 
Incomplete response, if overlapped dialing is enabled for SIP, then
the 484 Address Incomplete is forwarded back to the SIP phone and the
HANGUPCAUSE channel variable is set to 28.  Previously, the Incomplete
application dialplan logic was automatically triggered; now, explicit
dialplan usage of the application is required.

Additionally, this patch adds a new AST_CONTOL_FRAME type called
AST_CONTROL_INCOMPLETE.  If a channel driver receives this control frame,
it is an indication that the dialplan expects more digits back from the
device.  If the device supports overlap dialing it should attempt to 
notify the device that the dialplan is waiting for more digits; otherwise,
it can handle the frame in a manner appropriate to the channel driver.

    Sending out unnecessary PROCEEDING messages breaks overlap dialing.
    
    Issue #16789 was a good idea.  Unfortunately, it breaks overlap dialing
    through Asterisk.  There is not enough information available at this point
    to know if dialing is complete.  The ast_exists_extension(),
    ast_matchmore_extension(), and ast_canmatch_extension() calls are not
    adequate to detect a dial through extension pattern of "_9!".
    
    Workaround is to use the dialplan Proceeding() application early in
    non-dial through extensions.
    
    * Effectively revert issue #16789.
    
    * Allow outgoing overlap dialing to hear dialtone and other early media.
    A PROGRESS "inband-information is now available" message is now sent after
    the SETUP_ACKNOWLEDGE message for non-digital calls.  An
    AST_CONTROL_PROGRESS is now generated for incoming SETUP_ACKNOWLEDGE
    messages for non-digital calls.
    
    * Handling of the AST_CONTROL_CONGESTION in chan_dahdi/sig_pri was
    inconsistent with the cause codes.
    
    * Added better protection from sending out of sequence messages by
    combining several flags into a single enum value representing call
    progress level.
    
    * Added diagnostic messages for deferred overlap digits handling corner
    cases.

ec37ffbdaf ast_callerid restructuring
The purpose of this patch is to eliminate struct ast_callerid since it has
turned into a miscellaneous collection of various party information.

Eliminate struct ast_callerid and replace it with the following struct
organization:

struct ast_party_name {
	char *str;
	int char_set;
	int presentation;
	unsigned char valid;
};
struct ast_party_number {
	char *str;
	int plan;
	int presentation;
	unsigned char valid;
};
struct ast_party_subaddress {
	char *str;
	int type;
	unsigned char odd_even_indicator;
	unsigned char valid;
};
struct ast_party_id {
	struct ast_party_name name;
	struct ast_party_number number;
	struct ast_party_subaddress subaddress;
	char *tag;
};
struct ast_party_dialed {
	struct {
		char *str;
		int plan;
	} number;
	struct ast_party_subaddress subaddress;
	int transit_network_select;
};
struct ast_party_caller {
	struct ast_party_id id;
	char *ani;
	int ani2;
};

The new organization adds some new information as well.

* The party name and number now have their own presentation value that can
be manipulated independently.  ISDN supplies the presentation value for
the name and number at different times with the possibility that they
could be different.

* The party name and number now have a valid flag.  Before this change the
name or number string could be empty if the presentation were restricted.
Most channel drivers assume that the name or number is then simply not
available instead of indicating that the name or number was restricted.

* The party name now has a character set value.  SIP and Q.SIG have the
ability to indicate what character set a name string is using so it could
be presented properly.

* The dialed party now has a numbering plan value that could be useful to
have available.

The various channel drivers will need to be updated to support the new
core features as needed.  They have simply been converted to supply
current functionality at this time.


The following items of note were either corrected or enhanced:

* The CONNECTEDLINE() and REDIRECTING() dialplan functions were
consolidated into func_callerid.c to share party id handling code.

* CALLERPRES() is now deprecated because the name and number have their
own presentation values.

* Fixed app_alarmreceiver.c write_metadata().  The workstring[] could
contain garbage.  It also can only contain the caller id number so using
ast_callerid_parse() on it is silly.  There was also a typo in the
CALLERNAME if test.

* Fixed app_rpt.c using ast_callerid_parse() on the channel's caller id
number string.  ast_callerid_parse() alters the given buffer which in this
case is the channel's caller id number string.  Then using
ast_shrink_phone_number() could alter it even more.

* Fixed caller ID name and number memory leak in chan_usbradio.c.

* Fixed uninitialized char arrays cid_num[] and cid_name[] in
sig_analog.c.

* Protected access to a caller channel with lock in chan_sip.c.

* Clarified intent of code in app_meetme.c sla_ring_station() and
dial_trunk().  Also made save all caller ID data instead of just the name
and number strings.

* Simplified cdr.c set_one_cid().  It hand coded the ast_callerid_merge()
function.

* Corrected some weirdness with app_privacy.c's use of caller
presentation.

0122ccd29c Extract sig_ss7 out of chan_dahdi.
Extract the SS7 specific code out of chan_dahdi like what was done to
ISDN/PRI and analog signaling.  The new SS7 structures were modeled on
sig_pri.

The changes to sig_pri are an enhancement and a bug fix made possible
because SS7 was extracted.

1) The sig_pri TRANSFERCAPABILITY channel variable should have been set
unconditionally in sig_pri_new_ast_channel().

2) SS7/PRI transfer capability interaction in dahdi_new() fixed because of
SS7 extraction.

3) Module ref count error in dahdi_new() if startpbx failed to start the
PBX for some reason.
