Conversion to New ClassAds

This is part of ticket #187.

Analysis of Condor's use of old ClassAds

• Old ClassAd usage summary - A summary of the number of call sites in the Condor code for each Old ClassAds method.

• Old ClassAd usage details - Details of the number of call sites in the Condor code for each Old ClassAds method, and where it's called from.

• The wiki code for the individual calls is available in /p/condor/workspaces/nleroy/OldClassAdWiki -- the summary and detail files above are in there, as well as the code for each of the above, each in it's own file.

Additional conversion info

Direct use of ExprTree

Many parts of the code do the following to evaluate an expression in the context of a ClassAd:

• Parse() to create an ExprTree
• ExprTree::EvalTree() to evaluate it against an ad
• Examine the resulting ExprResult object

These need to be converted to the following sequence:

• ClassAdParser::ParseExpression()
• ExprTree::SetParentScope()
• ExprTree::Evaluate()
• Examine the resulting Value object

This work can probably be done mostly by a student.
