[PATH/RFC] Revert "compat: add strtok_r()"

[Erik Faye-Lund <kusmabite@gmail.com>]

This reverts commit 78457bc0ccc1af8b9eb776a0b17986ebd50442bc.

commit 28c5d9e ("vcs-svn: drop string_pool") previously removed
the only call-site for strtok_r. So let's get rid of the compat
implementation as well.

Conflicts:
	Makefile
	config.mak.in
	configure.ac
---

I just noticed that we have an unused compat-implementation of strtok_r,
so here's a patch to get rid of it.

 configure.ac      |  6 ------
