This is first script that init runs is rc.sysinit. This
script does serval initialization tasks about basic service.
The boot sequence currently provided to the board level is:
board_earlyinitialize->
board_lateinitialize(Peripherals driver, core driver, ...)->
run rcS script(mount fs, run service) ->
board_appinitialize->
After this patch:
The boot sequence currently provided to the board level is:
board_earlyinitialize->
board_lateinitialize(core driver,...)->
run rc.sysinit script(mount fs, run core service) ->
board_appinitialize(Peripherals driver)->
run rcS script(run other service)->
So, Peripheral drivers can do more with the file system and
core services.

Set the 'exit on error control' and/or 'print a trace' of commands when parsing scripts in NSH. The settinngs are in effect from the point of exection, until they are changed again, or in the case of the init script, the settings are returned to the default settings when it exits.
Included child scripts will run with the parents settings and changes made in the child script will effect the parent on return.
Use 'set -e' to enable and 'set +e' to disable (ignore) the exit condition on commands. The default is -e. Errors cause script to exit.
Use 'set -x' to enable and 'set +x' to disable (silence) printing a trace of the script commands as they are ececuted. The default is +x. No printing of a trace of script commands as they are executed.
Here are some offenders: examples/cc3000/shell.c, examples/nsh/nsh_main.c, examples/nxterm/nxterm_main.c, and examples/pty_test/pty_test.c. It is possible that for some of those, that represents the first call to nsh_consolemain(). But probably not.
To give other initialization options, I added nsh_consolechild() which is identical to nsh_consolemain() other than it omits all of the one-time initialization. Of course, you would not get the result that you wanted if nsh_consolechild() were called without nsh_consolemain().
