doc: add macros to unify command help with doxygen ...

Currently we have duplicated all the information that appears online in
'help <command>' and in the doxygen documentation. This patch adds some
infrastructure to specify help texts only once and re-use them for the
integrated help as well as for the manual.

command.h:98: Warning: Found unknown command `\t'

We accidently have two list implementations in the tree:
include/list.h and include/linux/list.h. This patch moves
the latter (newer one) to include/linux/list.h.

commands: remove maxargs ...

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.

This allows us to return COMMAND_ERROR_USAGE for

a very common case for commands.
