asterisk-chan-sccp: fix mwi header issue

Asterisk, somewhere between release 16.3.0 and 16.22.0, added a new
header "mwi.h". This causes compile failure, because the chan-sccp
snapshot is not aware.

asterisk-16.x: add patch for AST-2021-001

180-AST-2019-007-16.diff refreshed.

Upstream patch for AST-2021-001 added. This patch is mainly for
res_pjsip_diversion, but the part that is patched there was added later
("res_pjsip_diversion: implement support for History-Info"), so asterisk
16.3.0 is not affected. Hence the res_pjsip_diversion part was removed
from the patch. The patch resolves similar overflow situations in
res_pjsip_path and res_pjsip_outbound_registration, so these were kept.

asterisk-16.x: fix AST-2020-001 and 002

Patches used:

http://downloads.asterisk.org/pub/security/AST-2020-001-16.diff
http://downloads.asterisk.org/pub/security/AST-2020-002-16.diff

Patch AST-2020-002-16.diff was amended a bit in res/res_pjsip_session.c:

if (++session->authentication_challenge_count > MAX_RX_CHALLENGES) {
ast_debug(3, "%s: Initial INVITE reached maximum number of auth attempts.\n", ast_sip_session_get_name(session));
return PJ_FALSE;
}

The above was not possible, because of missing bits introduced only in a
later version of Asterisk 16 (see upstream commit [1]). So the ast_debug
call was simplified accordingly.

Both patches were refreshed within OpenWrt SDK.

[19.07] freeswitch-stable: prevent libcheck use

freeswitch-stable: prevent libcheck use

Currently we disable some sofia tests to prevent build failure. An issue
was actually raised upstream ([1]) where this was discussed.

This cleared up some doubts. For instance it was established that
libcheck is used as a test framework, if the lib is detected. In OpenWrt
libcheck is available, so it may be in staging during the freeswitch
build.

Upstream also mentioned that libcheck is not always compatible with
freeswitch, which depends on the libcheck version.

This commit prevents libcheck detection. This is nicer than explicitly
disabling tests that fail.

This commit addresses the recursive dependency of baresip-mod-pulse. The
new dependency string may look a bit peculiar, but it works and when
specified like this pulseaudio (when selected) doesn't get compiled
automatically when the intention is only to build baresip with mod-pulse
disabled (which in general is why we have the "patsubst" in the module
builder - but this is only triggered when the dependency has a leading
"+").

pjproject: add patches from asterisk's bundled pjproject

"check whether UPDATE is supported on outgoing calls", commit 5de36abd:

In ASTERISK-27095 an issue had been fixed because of which chan_pjsip was not
trying to send UPDATE messages when connected_line_method was set to invite.
However this only solved the issue for incoming INVITES. For outgoing INVITES
(important when transferring calls) the options variable needs to be updated
at a different place.

"Add patch for double free issue in timer heap", commit 9c11399b:

Fixed #2172: Avoid double reference counter decrements in
timer in the scenario of race condition between
pj_timer_heap_cancel() and pj_timer_heap_poll().

"Add timer patch from pjproject r5934", commit d4cd2a97.

asterisk-16.x: disable semaphores only on uClibc

The current patch disables semaphore use always. But musl and glibc
support semaphores. Only uClibc doesn't support them (the functions are
defined but just throw an error when called).

The patch is updated to allow Asterisk to use the system semaphores when
using anything but uClibc. It is also renamed to reflect that.

asterisk-16.x: update module descriptions

The current module descriptions look a bit topsy-turvy.

This updates the BuildAsteriskModule macro to simply take any sentence
(without trying to integrate the input into another string). If the
input contains '\n' a line break is inserted.

The module descriptions were updated from menuselect-tree.

asterisk-16: new package

asterisk-16.x: add Asterisk 16

Initial commit of Asterisk 16. Cleans up Makefile; the version number
now only occurs once in it.

Upstream removed the following modules:

  - format_jpeg
  - res_pjsip_registrar_expire (functionality was moved into
    res_pjsip_registrar.)

pjsip has a new dependency, res-http-websocket.

Notes:

  - replaced res_ninit patch

    Replaced patch with the one from Alpine. It's a bit more flexible and
    allows usage of res_ninit where available (when building against
    glibc).

  - fixed musl compiles

    astmm.h now always gets included by asterisk.h, redefining allocators.
    This causes breakage on musl:

    The problem is that with _GNU_SOURCE defined musl also declares calloc in
    <sched.h> - and when asterisk's source includes <sched.h> _after_
    "asterisk/astmm.h" the definition clashes with the macro. Timo Teräs from
    Alpine Linux fixed this by including <pthread.h> in "asterisk/compat.h". He
    chose to include <pthread.h> instead of <sched.h> because the original
    header inclusion chain seems to be "asterisk/astobj2.h" ->
    "asterisk/lock.h" -> <pthread.h> -> <sched.h>. It seems Asterisk
    practically never includes <sched.h> directly.

  - added loader workaround for musl

    When the modules are loaded, asterisk segfaults on musl.

       Asterisk Dynamic Loader Starting:
      [Mar  2 22:30:05] NOTICE[20712]: loader.c:2230 load_modules: 91 modules will be loaded.
      Segmentation fault

      [48817.544248] do_page_fault(): sending SIGSEGV to asterisk for invalid read access from 00000000
      [48817.544258] epc = 77f6b764 in libc.so[77ef8000+94000]
      [48817.544285] ra  = 0048d579 in asterisk[400000+160000]

    The real problem is that the loader expects dlopen to always run the
    constructor, which doesn't happen with musl, because its dlopen is
    permanent.

    This commit adds a new configure switch '--enable-permanent-dlopen'.
    When enabled, the loader will manually call 'ast_module_register(...)'
    and 'ast_module_unregister(...)' when needed.

  - allow eventfd detection

    Asterisk 16 wants to use eventfd, but it doesn't allow the detection
    during cross-compiling. This results in runtime warnings, for instance
    when shutting down:

      [Mar  2 22:37:41] WARNING[21593]: alertpipe.c:112 ast_alertpipe_read: read() failed: Bad file descriptor
      [Mar  2 22:37:41] WARNING[21593]: alertpipe.c:112 ast_alertpipe_read: read() failed: Bad file descriptor
      [Mar  2 22:37:41] WARNING[21593]: alertpipe.c:112 ast_alertpipe_read: read() failed: Bad file descriptor

    Relax the configure script so that eventfd can also be detected when
    cross-compiling.
