directory paths on Windows ("/c:/foo/bar.usd"). Just add a simple check for
the infinite recursion rather than trying to figure out and avoid conditions
that might lead to it.
… raise an exception if this function is passed a non-canonical Windows path.
A symlink can specify either an absolute or relative path. This change adds a check for the "relative" flag, and converts the symlink path to a full path, since that's what callers to this function assume will be returned.
Tests absolute paths without drive latters, relative paths, and some more challenging symlink tests, including resolving symlinks while inside a symlink directory.

Description of Change(s)
This started as an attempt to fix a possible exception when handling paths starting with "/" in the code for #1441 and then write some additional tests. But my test cases kept failing. Turns out there were still issues in handling on non-mountpoint symlinks on Windows. There was also the potential for infinite recursion in Tf_MakeDirsRec when it was passed a malformed path.
Also adding the test cases that were failing without all these fixes.
Relates to #1441, #1378.
