Integrate recent changes to asterisk port in asterisk11 and asterisk13
ones:

This port now supports custom Asterisk configurations using a
*user-supplied* menuselect.makeopt file.

This feature is of most value for users that want to disable or
override default functionality that they dont want or need, particular
in space and/or resource constrained, or embedded environments.

For more information see this ports pkg-message file.

OPTIONS Changes:

• Make speex, libexecinfo and mpg123 OPTION'al
• Make menuselect backends (curses/newt) OPTION'al
• Remove override-able OPTION descriptions (dont appear necessary)
• Add CODECS, SOUNDS and DATABASE options groups for better UX
• Improve OPTION descriptions

General Changes:

• Add support for fetching G.279 Core and MOH sounds
• Use %%DATADIR%% in pkg-plist (portlint)
• Make DATADIR-safe (portlint)
• Reset @owner/@group after pkg-plist entries
• Pass CFLAGS/LDFLAGS to ASTCFLAGS/ASTLDFLAGS respectively in MAKE_ENV
• Update and cleanup pkg-plist
• Bump PORTREVISION

While here:

• Convert to USE_SQLITE in place of explicit LIB_DEPENDS.
