common: command: Add command execution tracer.
When using boot scripts it can become quite hard to understand
which commands are actually executed during bootup (e.g. where
is a kernel image loaded from or which DTB is in use).
Shell scripts suffer from a similar problem and many shells address
this problem with a command execution tracer (e.g. BASH has xtrace,
which can be enabled by "set -x").
This patch introduces a command tracer for U-Boot, which prints
every command with its arguments before it is executed.
