utils: drop strtok_r from envlist_parse
The problem is that mingw 4.9.1 fails to compile the code with the following warning: /mingw/include/string.h:88:9: note: previous declaration of 'strtok_r' was here char *strtok_r(char * __restrict__ _Str, const char * __restrict__ _Delim, char ** __restrict__ __last); /include/sysemu/os-win32.h:83:7: warning: redundant redeclaration of 'strtok_r' [-Wredundant-decls] char *strtok_r(char *str, const char *delim, char **saveptr); The problem is that compiles just fine on previous versions of mingw. Compiler version check here is not a good idea. Though fortunately strtok_r is used only once in the code and we could simply rewrite the code without it.
