[PATCH 0/2] Use std::hashmap and MI commands classes in mi-cmds.c

[didier dot nadeau at gmail dot com]

From: Didier Nadeau <didier.nadeau@gmail.com>

This is a serie of two patches in preparation to a next patch that will allows
users to define custom MI commands using Python, similarly to what is currently
possible for Python CLI commands. 

The first patch modify mi-cmds.c to use an std::hashmap to store MI commands 
instead of the custom structure. It allows to insert new MI commands at runtime
as it does not use a fixed size array anymore.

The second patch removes structures mi_cli and mi_cmd from mi-cmds.c and replace
them with a hierarchy of classes. This way, each subtype of MI command inherits
from the base virtual class and register itself into the hashmap. Classes 
mi_command_mi for pure MI commands and mi_command_cli for MI commands over CLI
commands have been implemented. MI commands are now all called from a common
invoke virtual function. Logic for suppress_notification and ARGV/ARGC parsing 
has been moved to the classes implementation.

Didier Nadeau (2):
  Use std::map for MI commands in mi-cmds.c
  Use classes to represent MI Command instead of structures
