[Qemu-devel] [PULL 07/16] monitor: Rename HMP command type and tables

[Markus Armbruster]

From: Kevin Wolf <address@hidden>

This renames the type for HMP monitor commands and the tables holding
the commands to make clear that they are related to HMP and to allow
making them public later:

* mon_cmd_t -> HMPCommand (fixing use of a reserved name, too)
* mon_cmds -> hmp_cmds
* info_cmds -> hmp_info_cmds

[sortcmdlist() cleaned up to make checkpatch.pl happy]
