bug 4056

Given a configuration with TopologyParam including Dragonfly option, if a
job requested --switches count, the count timeout specified by either
the job request or max_switch_wait SchedulerParameters was not respected.
This was due to leaf_switch_count variable not being incremented in
_eval_nodes_dfly() function when needed, as we do in _eval_nodes_topo(),
the later being a execution path which already succeed to wait for the
switch count timeout.

Bug 3988

srun jobs that could start immediately and requested multiple partitions
didn't run in the highest priority partition if the highest priority
partition wasn't listed first.

It's possible that the scontrol show jobs will show the partition list
in priority order now that the job's partition list gets sorted by
priority.

Bug 4015

NULL is returned if the token is not found, testing against '\0'
is wrong (although does work okay in older compilers).

Fixes new GCC 7.1 warning.
