[asterisk-commits] main/pbx: Move pbx builtin dialplan applications to pbx buil... (asterisk[master])

main/pbx: Move pbx_builtin dialplan applications to pbx_builtins.c

We joked about splitting pbx.c into multiple files but this first step was
fairly easy.  All of the pbx_builtin dialplan applications have been moved
into pbx_builtins.c and a new pbx_private.h file was added. load_pbx_builtins()
is called by asterisk.c just after load_pbx().

A few functions were renamed and are cross-exposed between the 2 source files.

-			<para>This function can be used to set the value of channel variables or dialplan functions.
-			When setting variables, if the variable name is prefixed with <literal>_</literal>,
-			the variable will be inherited into channels created from the current channel
-			If the variable name is prefixed with <literal>__</literal>, the variable will be
-			inherited into channels created from the current channel and all children channels.
-			MSet behaves in a similar fashion to the way Set worked in 1.2/1.4 and is thus
-			prone to doing things that you may not expect. For example, it strips surrounding
-			double-quotes from the right-hand side (value). If you need to put a separator
-			character (comma or vert-bar), you will need to escape them by inserting a backslash
-			before them. Avoid its use if possible.</para>
