Style: replace "!rank" with "rank == 0"

In SF tutorial ex1 (src/vec/is/sf/tutorials/ex1.c), add parentheses around "rank == 0". This is relevant because ! binds more tightly than +, but == binds less
tightly, so the result of the computation would otherwise change.

This example seems to demonstrate that one cannot construct a DMNetwork with one subnetwork in parallel correctly.

DMNetworkAddSubnetwork() does not need input nv; optimize DMNetworkLayoutSetUp_Coupling() and DMNetworkLayoutSetUp()
bugfix for DMNetworkDistribute(): subnet[].nvtx was over counted
cleanup network.c; add '-malloc_dump 0' to ex10.c: otherwise opensolaris-misc pipeline test fails
use the fix suggested by Satish. This fixes the opensolaris-misc pipeline test error of ex10.c, and harmless to other cases
rm #if 0. Previously kept for future work

Add interface to libcams

- CAMS also work for stiffly-accurate methods. The last stage points to the solution vector ts->vec_sol. This feature is leveraged in CAMS checkpointing to reduce the memory cost.

- Add option -ts_trajectory_max_units_ram
- Added -ts_trajectory_max_units_ram and -ts_trajectory_max_units_disk to specify the number of available checkpointing units.
- Conceptualy a checkpoint may contain multiple checkpointing units (solution and stage values) of the same size.
- Users should use either max_units or max_cps, but not both at the same time.
