Previous commits maintained compatibility with older remote console
clients as well as maintaining all API's.

* ast_cli_generatornummatches.
* Remote command "_command nummatches".
* Sorting / duplicate removal by remote console.

The patch for ASTERISK_24560 inverted a test checking if the bridge name
is being updated to a different name.

* Fix the test to return "Changing bridge name is not implemented" when
someone attempts to change the bridge name.

Although the default value of defaultbranch is master I'm adding it
anyways.  This way when new major branches are being created the value
can be updated instead of having to remember the name of the key.

If a 183 with sdp response is receive without a To tag the sdp is not
negotiated. According to RFC 3261 section 12.1.2 while a To tag is required,
the client needs to still be able to handle the missing tag case for
backwards compatibility.

This patch, accepted by and applied to pjproject, makes it so if an incoming
180/183 with SDP comes in without a To tag it gets appropriately handled.

Previously, Asterisk sent srflx only when configured exclusively for IPv4. Now,
srflx is gathered and sent via SDP, even when Asterisk is enabled for
Dual Stack (IPv4+IPv6) and an IPv4 interface is available/used.

res_parking had an inplicit load_pri of 0 meaning it was one of the very
first modules loaded after modules with global symbols.  Set it to
AST_MODPRI_DEVSTATE_PROVIDER as it provides device state for parking
lots.

Convert the README file to markdown format, remove the old README.  This
causes websites like github to display the README in a much nicer
format with live links.  The raw file is still very readable from
plain text editors and terminals.

* Stop using "_COMMAND NUMMATCHES" on remote consoles.  Using this
  command had doubled the amount of work needed from the Asterisk
  daemon for each completion request.
* Fix code formatting.
* Remove static buffer used to send the command, use the same buffer
  that will receive the results.
* Move sort from ast_cli_display_match_list.

This rewrites ast_el_strtoarr to use vector's internally, but still
return the original NULL terminated array of strings.

* Stop estimating line count, just print until we run out of matches.
* Stop freeing entries, the caller does that anyways.
* Stop calculating / returning numoutput, it was ignored.

Some completion generators are very inefficent due to the way CLI
requests matches one at a time.  ast_cli_completion_add can be called
multiple times during one invokation of a CLI generator to add all
results without having to reinitialize the search state for each match.
