refactor-queryCallback-with-inbuilt-query-functions

[chapmandu]

• Speed this up by eliminating list functions
• Use ACF2016+ inbuilt query functions

Performance test results:

(Before) With callback (ListFindNoCase)
afterfind-callback-ListFindNoCase 15145ms

(After) With callback (QueryKeyExists)
afterfind-callback-QueryKeyExists 1474ms

Without callback (afterfind callbacks are evil due to query row to struct creation on each row)
without-callback 232ms

Test code

// test.cfm
cftimer(label = "afterfind", type = "debug") {
	loop from=1 to=20 index="i" {
		model("User").findAll(maxrows = 100, reload = true);
	}
}

// models/User.cfc
afterFind("do");
...
function foo() {
	arguments.foo = true;
	arguments.bar = true;
	arguments.baz = true;
	arguments.qux = true;
	return arguments;
}

@chapmandu are you still working on this PR?

I'll have another look today and see where it's at.

I'm going to do some performance comparisons to see what gains are to be had.
