Standardise layout and naming in corelib benchmarks

Make file names match CMake's test names (and those follow dir-name)
and class names follow tst_ClassName pattern when testing
ClassName. Purge comments about the qmake configs the CMakeLists.txt
are generated from.  Purge empty constructors and init/cleanup methods
of classes.  Fix petty coding style violations.

Add qdir/tree/, qurl, qbench and qset benchmarks to their parent directories'
lists of subdirs. Fix unused return error from qurl benchmark.
