Title: Fixed some compilation errors/warnings in C examples

* ```zhash_foreach``` handler accepts ```const char *```, but all prototypes were ```char *```
* ```lruqueue.c``` was using ```workers``` variable which doesn't exist.
* A couple of files used uuid generation, for which ```-luuid``` is required.
