Try to avoid problems when the job record is changed.

Conflicts:
	src/plugins/accounting_storage/mysql/as_mysql_acct.c

Set job state to JOB_BOOT_FAIL when boot fails, JOB_NODE_FAIL on
cnode or other hardware failure, otherwise set to JOB_FAILED

In commit ba54c8b4 it was changed
from JOB_FAILED to JOB_NODE_FAIL. JOB_BOOT_FAIL will probably be
more accurate reason

In commit ba54c8b4 the job exit
state was changed to JOB_BOOT_FAIL, which is wrong

Make it work on PERCS system.
Add job time limit to avoid indefinite hang
Purge vestigial file from previous run
Exit on fatal condition rather than trying to continue execution

Mostly adding "return" statements after calls to fatal();
