Merge branch 'features' of github.com:avadhpatel/marss into features
Added option -n --num-insts to run_bench.py

Instead of specifying multiple disk images in configuration now run_bench.py
uses -snapshot qemu option by default and provides new cmd-line option to
specify number of simulation instances to run in parallel.

Changed from SafeConfigParser to ConfigParser

To enable recursive interpolation. This helps a lot to reduce the size of run
configuration file.

Merge pull request #10 from stefanneumann/features

Fix: Switch to simulation now follows immediately after ptlcall
New Feature: Fast-Fwd N instruction before starting simulation

To fast-forward by N number of instructions specify follwoing simconfig option:

    -fast-fwd-insns N

This will emulate N number of instructions and then switch to simulation mode.

For multicore mode N number of instructions are equally divided between
existiting cores in system.  If core is halted/idle mode then its allocated
instructions will be shared among other cores that are active.
