This change introduces MODULEINFO into many modules in Asterisk in order to show the community support level for those modules. This is used by changes committed to menuselect by Russell Bryant recently (r917 in menuselect). More information about the support level types and what they mean is available on the wiki at https://wiki.asterisk.org/wiki/display/AST/Asterisk+Module+Support+States ........ ................ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@328259 65c4cc65-6c06-0410-ace0-fbb531ad65f3

<para>The EXTENSION_STATE function can be used to retrieve the state from any
|
|
hinted extension. For example:</para>
|
|
<para>NoOp(1234@default has state ${EXTENSION_STATE(1234)})</para>
|
|
<para>NoOp(4567@home has state ${EXTENSION_STATE(4567@home)})</para>
|
|
<para>The possible values returned by this function are:</para>
|
|
<para>UNKNOWN | NOT_INUSE | INUSE | BUSY | INVALID | UNAVAILABLE | RINGING |
|
|
RINGINUSE | HOLDINUSE | ONHOLD</para>
