shell: add help command 

The help command currently only lists available commands. It was asked
by some developers some time ago, and this implementation only costs
150 bytes in the final exectuable.  I don't think it's worth a Kconfig
option.

This is it in action with my configuration:

   wrc# help
   Available commands:
     ver
     pll
     sfp
     stat
     ptp
     mode
     calibration
     time
     gui
     sdb
     mac
     init
     ptrack
     ip
     verbose
     help
