When 'tlsclientmethod' is not specified in sip.conf, chan_sip uses the OpenSSL
SSLv23_method. This was documented incorrectly in the file sip.conf.sample.

SSLv23_method got its name in the 90s. Today, with OpenSSL 1.0.2, this method
enables (just) the secure TLSv1.0 and TLSv1.2. Or stated differently, that
function should have been called 'secure_method' or 'automatic_method' back in
the 90s.

Consequently please, specify 'tlsclientmethod=tlsv1' in your sip.conf only if
you face a server which has problems like not falling back to TLSv1.0
automatically.

This updates func_channel.c and main/message.c to use a generic xpointer
include instead of including info from each channel driver.  Now the
name attribute of info is CHANNEL or CHANNEL_EXAMPLES to be included in
documentation for func_channel.  Setting the name attribute of info to
MessageToInfo or MessageFromInfo causes it to be included in the
MessageSend application and AMI action.

Packets are read regulary, when there is no data in buffer fr->frametype
is AST_FRAME_NULL. There was no check of frametype and lastrtprx always 
updated and, therefore, rtptimeout did not work at all.

The Exchanging Device and Mailbox States could not working
if the Entity ID (EID) is not set manually and can't be obtained
from ethernet interface.

This patch replaces debug message to warning
and addes missing description about option 'entityid' to
asterisk.conf.sample.

With this patch the asterisk also:
(1) decline loading the modules which won't work without EID:
    res_corosync and res_pjsip_publish_asterisk.
(2) warn if EID is empty on loading next modules:
    pbx_dundi, res_xmpp

Starting with v197 systemd/udev will automatically assign "predictable"
names for all local Ethernet interfaces.
This patch also addes some new ethernet prefixes "eno" and "ens".

* Remove some unused parameters from internal functions:
sorcery_wizard_create()
sorcery_wizard_update()
sorcery_wizard_delete()

* Created the struct sorcery_observer_invocation ao2 object without a lock
since it is not needed in sorcery_observer_invocation_alloc().

* Cleanup generic ao2 container sorcery object id hash, sort, and cmp
functions.

Change-Id: Iff71d75f52bc1b8cee955456838c149faaa4f92e

* Tweak sorcery_object_type_alloc() formatting.
* Tweak ast_sorcery_init() formatting.

Do not check registrar of the first extension head.  We should only check
the registrar when we match the priority.

Additionally fix a couple calls to strcmp which used the input callerid
instead of the clean version ex.cidmatch.

* Add some helpful <literal> and other embedded paragraph tags

* Document some of the lesser known channel variables set by Dial

* Add examples for some common Dial uses, along with some more
  challenging but useful options

* Groups of AGI commands that have similar functionality now reference
  each other, and all reference the AGI application for ease of wiki
  reference.

* The documentation for the AGI application has been improved, in
  particular noting the various AGI types and how they are invoked.

* A warning message has been added to DeadAGI, noting that it is
  deprecated.

This patch adds some see-also references between related AMI events. It
focuses primarily on those events that are guaranteed to come in pairs,
such as DTMFBegin/DTMFEnd, as well as those that occur during the life
cycle of an Asterisk channel, such as Newchannel/Hangup.

* Following the example of the PJSIP channel driver, the channel
  technology specific documentation has been moved to the respective
  channel drivers that provide that functionality. This has the benefit
  of locating the documentation of items with those modules that provide
  it.

* Examples of using the CHANNEL function for both standard items as well
  as for PJSIP have been added.

* The 'max_forwards' standard item has been documented.
