Running slurmctld under valgrind while operating with jobcomp/elasticsearch
reported the following bytes definitely lost:

It turns out the generated buffer in slurm_jobcomp_log_record was xstrdup'ed to
the corresponding job_node->serialized_job, but the originally generated buffer
wasn't freed afterwards. The fix consists in change the transfer so that instead
of xstrdup'ing the char * we just assign the pointer and NULL the buffer.

The job_node->serialized_job was already xfree'd properly later when the job
was indexed.

Discovered while working on Bug 4065.

This should only happen due to ESLURM_RESULT_TOO_LARGE,
which leads to no list being packed.

Otherwise the resulting URL may be invalid. Update documentation
while here as well.

Bug 4065.

Otherwise a race between threads in _check_node_status leads
to a crash.

The exit status value for these two fields was incorrectly saved as-is.  The
patch makes use of the appropiate macros to properly decode the low-order
8 bits of the exit status and the signal number (if any).

bug 3942

Print numbers using exponential format if required to fit in allocated
    field width. The sacctmgr and sshare commands are impacted.
bug 1749

was removed in 2705f9c5.
Caused sview to crash when viewing the debug_flags.

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.

Add the following fields as environment variables:
CLUSTER, DEPENDENCY, DERIVEDEC, EXITCODE, GROUPNAME, QOS, RESERVATION,
USERNAME.

LIMIT env variable value format (which means the TimeLimit of the job)
has been modified to D-HH:MM:SS.
