Added comment about __progname and environ being needed for FreeBSD to
prevent accidental removal in the future.

./configure --with-pjproject-bundled
did not display an explanation, when no download utility like wget, curl, or
fetch was installed beforehand, although an explanation existed in code. This
happened because the code expected the variable DOWNLOAD_TO_STDOUT to be empty.
However, the script ./configure set that variable always.

Certain applications (e.g. door-phone) require that also video is transmitted
before a call is accepted.

Nine years ago with Mantis 13639 (now ASTERISK-12841) an extra case for OpenBSD
was introduced: Vorbis required Ogg to be specified manually, because the shared
library libvorbis.so did not specify its required dependency on -logg itself.

Today with OpenBSD 6.2, all libvorbis*.so declare their dependencies correctly.
Therefore, an extra case is not required anymore.

When app_voicemail calls ast_test_suite_notify with the results of
a user keypress, it formats the keypress as '%c'.  If the user hung up
or some other error occurrs, the result of the keypress is a non
printable character.  This ultimately causes json_vpack_ex to think
it's being passed a non utf-8 string and return an error.

* Keypress results passed to ast_test_suite_notify are now checked with
  isprint() and a '?' is substituted if the check fails.

These modules are now loaded at appropriate time by the module loader.
Unlike loadable modules these use AST_MODULE_LOAD_FAILURE on error so
the module loader will abort startup on failure of these modules.

Some of these modules are still initialized or shutdown from outside the
module loader.  logger.c is initialized very early and shutdown very
late, manager.c is initialized by the module loader but is shutdown by
the Asterisk core (too much uses it without holding references).

GCC documentation states that when __attribute__((malloc)) is used it
should not return storage which contains any valid pointers.  It
specifically mentions that realloc functions should not have the malloc
attribute, but this also means that complex initializers which could
contain initialized pointers should not use this attribute.

When built-in components of Asterisk fail to start they cause the
Asterisk startup to abort.  In these cases only the most critical
cleanup should be performed - closing databases and terminating
proceses.  These cleanups are registered using ast_register_atexit, all
other cleanups should not be run during startup abort.

The main reason for this change is that these cleanup procedures are
untestable from the partially initialized states, if they fail it could
prevent us from ever running the critical cleanup with ast_run_atexits.

Create separate initialization for dns_core.c to be run unconditionally
during startup instead of being initialized by the first dns resolver to
be registered. This ensures that 'sched' is initialized before it can be
potentially used.

Replace ast_register_atexit with ast_register_cleanup in media_cache.c.
There is no reason for this cleanup to happen unconditionally.
