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.

Telephony packages feed
Description
This is an OpenWrt package feed containing community maintained telephony packages.
Usage
To use these packages, add the following line to the feeds.conf in the OpenWrt buildroot:
src-git telephony https://github.com/openwrt/telephony.git
This feed should be included and enabled by default in the OpenWrt buildroot. To install all its package definitions, run:
./scripts/feeds update telephony
./scripts/feeds install -a -p telephony
The telephony packages should now appear in menuconfig.
