$((10#$SLURM_API_MAJOR)) is bash-specific. replace with portable
${SLURM_API_MAJOR#0} which accomplishes the same thing.

The first forces bash to treat the value as base-10 even with a
leading zero, the second portable format strips a leading zero off.

Also remove checks for sys/termios.h from build system.
Slurm directly includes the POSIX-required <termios.h> already,
and the one use of this conditional is being removed here.

Fixes one of several build errors on FreeBSD.

This fixes a bug introduced in commit a801d264
Whole node resource allocations with REPLACE option were not working.

Support AuthInfo in slurmdbd.conf that is different from the value in
    slurm.conf.
There is a possible bug in the slurm_get_auth_info function (src/common/slurm_protocol_api.c) that can cause the slurmdbd daemon to look for the AuthInfo parameter in slurm.conf instead of slurmdbd.conf when the auth/munge authentication method is used (AuthType=auth/munge).

Here is the slurmdbd log revealing the problem (debug5() printing were added in the sources) :

slurmdbd: slurmdbd version 15.08.7 started

...

Then 60 seconds later, the auth_info value returned by slurm_get_auth_info is NULL:

slurmdbd: debug5: Leaving ../../../src/common/slurm_protocol_api.c, slurm_get_auth_info, auth_info=(null)

and slurmdbd continues without crashing, but I am not sure it is in a safe state.

When applying this patch :

        return auth_info;
 }

the auth_info value is now valid and consistent with the slurmdbd.conf setting:

$((10#$SLURM_API_MAJOR)) is bash-specific. replace with portable

The first forces bash to treat the value as base-10 even with a

Including setting of default MCDRAM and NUMA modes

When the slurmctld is in background mode, it will issue double
  free calls on the incomming message buffers, likely leading
  an abort.

If an invalid trigger message is received by slurmctld, it could
  result in a non-zero array counter and a NULL element array.
  If the element array is NULL, then clear the counter to avoid
  xfree calls of bad pointers.

Do not automatically relocate an advanced reservation for individual cores
    that spans multiple nodes when nodes in that reservation go down (e.g.
    a 1 core reservation on node "tux1" will be moved if node "tux1" goes
    down, but a reservation containing 2 cores on node "tux1" and 3 cores on
    "tux2" will not be moved node "tux1" goes down). Advanced reservations for
    whole nodes will be moved by default for down nodes.
