command context: fix errors when running certain commands on startup
Various commands, e.g. "arm mcr xxxx" would fail if invoked upon startup since it there was no command context defined for the jim interpreter in that case. A Jim interpreter is now associated with a command context(telnet, gdb server's) or the default global command context. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
