Fix various harmless cases of undefined behaviour, and add a Travis
job testing under UBSan.
* poll/unix/poll.c (apr_poll): For the on-stack array allocation use
num+1 since allocating a 0-length array is undefined behaviour.
* tables/apr_skiplist.c (get_b_rand): Use unsigned integers to avoid
signed integer overflow in the left shift.
(skiplist_qpush): Avoid calling memcpy(,NULL,0).
* random/unix/apr_random.c (apr_random_add_entropy): Avoid calling
memcpy(,NULL,0).
* test/teststr.c (overflow_strfsize): Avoid signed integer overflow.
