Fix some typos and improve technical content of the SLURM design
documents for job launch and gres support.

Added a web page to describe the job launch and termination process
and made a minor enhancement to the GRES design document.

Patch from Andriy Grytsenko (Massive Solutions Limited).

Synchronize power-save module better with scheduler.
Without this change, returning a node to service was typically
delayed longer than necessary.

Report scontrol job job PreemptTime=None rather than PreemptTime=NO_VAL
if not set. Patch from Bill Brophy, Bull

This expands the description of how to build slurm using a git repository.

Modify job expansion logic to support licenses, generic resources, and
currently running job steps in the job which is expanding.

Logging message was misleading and incorrect pointer used in another.

Former logic failed to properly allocate resources to a job step
when specifying both a task count and a node count range on a
heterogeneous cluster.

BLUEGENE - Fixed print of geo portion of the select_jobinfo struct to work correctly with the regession tests.

Latest Cray-specific modifiations

The enum is only needed and referenced in basil_geometry() and has otherwise
no special meaning since it directly depends on the selected output columns.
Patch from Gerrit Renker, CSCS.

This case was observed after taking a blade out of a CLE 2.x system. ALPS does not
list the removed nodes, but they still appear in the XTAdmin.processor table, with
NULL coordinates. Hence set node down if at least one coordinate is NULL.

Also add a check to compare how many out of the nodes in slurm.conf are visible to
ALPS (the absence of this test masked the bug), always list DOWN nodes at startup,
and clarify that not failing due to ALPS errors during the initial SLURM
configuration is not an option.

On the system which is missing a blade, the log information now is
 [2011-05-16T16:09:54] error: ALPS sees only 12/16 slurm.conf nodes

This fixes some errors in the documentation of how memory is allocated, and adds missing bits.

BLUEGENE - Added block node cnt to be able to differentiate between a sub-block job and a regular full block job.

Conflicts:
	src/plugins/select/bluegene/bg_record_functions.c

BLUEGENE - if a block goes into an error state.  Fix issue where accounting wasn't updated correctly when the block was resumed.

Clearly document that only PreemptType=preempt/partition_prio can be
used with PreemptMode=suspend. Only partition data structures exist in
the module that suspends and resumes jobs.

The node state was formerly reported "UNKNOWN" on node state change
request errors.

This restores proper slurmd hostname resolution on Frontend systems
(BlueGene and Cray) which was broken by commit 635abaea
adding support for the slurmd -f option.
