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.
