getTargetVariableExpandedUrl() function

Given a redirect definition and an incoming URL, calculate what the final outgoing URL is to be. Wildcards in the target are filled from the matching source wildcards; a source splat can be written in the target either as * or as :splat.

isVariable overrides which source path segments count as wildcards. It receives whether the segment is the last one in the source, which is what distinguishes a trailing splat from a literal *; a callback that ignores it cannot match splats. The default accepts both.
