Merge changes from team/group/appdocsxml

This commit introduces the first phase of an effort to manage documentation of the
interfaces in Asterisk in an XML format.  Currently, a new format is available for
applications and dialplan functions.  A good number of conversions to the new format
are also included.

For more information, see the following message to asterisk-dev:

<para>STRFTIME supports all of the same formats as the underlying C function

It also supports the following format: <literal>%[n]q</literal> - fractions of a second,

<para>Example: <literal>%3q</literal> will give milliseconds and <literal>%1q</literal>
will give tenths of a second. The default is set at milliseconds (n=3).
The common case is to use it in combination with %S, as in <literal>%S.%3q</literal>.</para>

<synopsis>
Evaluate stored variables

<description>
<para>Using EVAL basically causes a string to be evaluated twice.
When a variable or expression is in the dialplan, it will be
evaluated at runtime. However, if the results of the evaluation
is in fact another variable or expression, using EVAL will have it
evaluated a second time.</para>
<para>Example: If the <variable>MYVAR</variable> contains
<variable>OTHERVAR</variable>, then the result of ${EVAL(
<variable>MYVAR</variable>)} in the dialplan will be the
contents of <variable>OTHERVAR</variable>. Normally just
putting <variable>MYVAR</variable> in the dialplan the result
would be <variable>OTHERVAR</variable>.</para>
