pw_tokenizer: Multiple tokens from one macro

In some cases it is desirable to have a macro that expands to multiple
tokenizer calls. Previously, the __LINE__ macro was used to name
intermediate variables for tokenizing; however, this doesn't work when a
macro expands to multiple tokenizations. This patch switches to the
__COUNTER__ macro which will work correctly even in the case of multiple
tokenizations in one macro expansion.
