[trac4480] Update per review comments

Browse Source 
Create a LogContentTest class and move the functions to manipulate
a test to check on the log output there.  This will make it available
for other tests in the future.  As part of this bundle a bit more
work into the class to minimze the calls in the test routines.

Where reasonable remove extra copys of the values being pushed
onto the stack - instead of generating a copy just for the logging
simply use the value from the top of the stack directly.

Swtich to using single quotes around text values.

Added some more description in the classify document

Add debug logging to the classification tokens.
Add debug logging to the classification tokens. This uses
the loggers "kea-dhcp4.eval" and "kea-dhcp6.eval" to capture
details of the classification expression evaluations.

The specific loggers are "kea-dhcp4.eval" and "kea-dhcp6.eval".

<para>
In order to understand the logging statements one must understand a
bit about how expressions are evaluated, for a more complete description
refer to the design document at <ulink url="http://kea.isc.org/wiki/KeaDesigns"/>.
In brief there are two structures used during the evaluation of an expression
a list of tokens which represent the expressions and a value stack which
represents the values being manipulated.
</para>
<para>
The list of tokens is created when the configuration file is processed with
most expressions and values being converted to a token. The list is organized
in reverse polish notation. During execution the list will be traversed
in order. As each token is executed it will be able to pop values
from the top of the stack and eventually push its result on the top of the
stack. Imagine the following expression:
<screen>
"test": "substring(option[61].hex,0,3) == 'foo'",
</screen>
This will result in the following tokens:
<screen>
option, number (0), number (3), substring, text ('foo'), equals
</screen>
In this example the first three tokens will simply push values onto the
stack. The substring token will then remove those three values and
compute a result that it places on the stack. The text option also
places a value on the stack and finally the equals token removes the
two tokens on the stack and places its result on the stack.
</para>
<para>
When debug logging is enabled each time a token is evaluated it will
emit a log line indicating the values of any objects that were popped
@ -678,8 +708,12 @@
The debug logging may be quite verbose if you have a number of expressions
to evaluate. It is intended as an aide in helping you create and debug
your expressions. You should plan to disable debug logging when you have your
expressions working correctly. You also may wish to debug only one set of
expressions at a time to limit the log statements.
expressions working correctly. You also may wish to include only one set of
expressions at a time in the configuration file while debugging them in order
to limit the log statements. For example when adding a new set of expressions
you might find it more convenient to create a configuration file that only
includes the new expressions until you have them working correctly and then
add the new set to the main configuration file.
