configuration conditions.

Markus Armbruster 1527badb95 qapi: Support multiple command registries per program
The command registry encapsulates a single command list.  Give the
functions using it a parameter instead.  Define suitable command lists
in monitor, guest agent and test-qmp-commands.

Eric Blake 42a502a7a6 qmp: Drop dead command->type
Ever since QMP was first added back in commit 43c20a43, we have
never had any QmpCommandType other than QCT_NORMAL.  It's
pointless to carry around the cruft.

Mark Wu 0106dc4f05 qemu-ga: Extend 'guest-info' command to expose flag 'success-response'
Now we have several qemu-ga commands not returning response on success.
It has been documented in qga/qapi-schema.json already. This patch exposes
the 'success-response' flag by extending 'guest-info' command. With this
change, the clients can handle the command response more flexibly.

Mark Wu 8dc4d915dd qemu-ga: Add interface to traverse the qmp command list by QmpCommand
In the original code, qmp_get_command_list is used to construct
a list of all commands' name. To get the information of all qga
commands, it traverses the name list and search the command info
with its name.  So it can cause O(n^2) in the number of commands.

This patch adds an interface to traverse the qmp command list by
QmpCommand to replace qmp_get_command_list. It can decrease the
complexity from O(n^2) to O(n).

Eduardo Habkost ccff63cac4 qapi/qmp-registry.c: Include headers it needs
Include:
- <glib.h> for g_malloc0()
- <string.h> for strcmp()

Some of those headers were probably being included by accident because
some other headers were including qemu-common.h, but those headers
should eventually stop including qemu-common.h.

Luiz Capitulino d34b867d81 qapi: add support for command options
Options allow for changes in commands behavior. This commit introduces
the QCO_NO_SUCCESS_RESP option, which causes a command to not emit a
success response.

This is needed by commands such as qemu-ga's guest-shutdown, which
may not be able to complete before the VM vanishes. In this case, it's
useful and simpler not to bother sending a success response.

Michael Roth f22d85e9e6 qemu-ga: add a whitelist for fsfreeze-safe commands
Currently we rely on fsfreeze/thaw commands disabling/enabling logging
then having other commands check whether logging is disabled to avoid
executing if they aren't safe for running while a filesystem is frozen.

Instead, have an explicit whitelist of fsfreeze-safe commands, and
consolidate logging and command enablement/disablement into a pair
of helper functions: ga_set_frozen()/ga_unset_frozen()

Michael Roth bf95c0d55c guest agent: add supported command list to guest-info RPC
Not that there is blacklisting functionality we can no longer infer
the agent's capabilities via version. This patch extends the current
guest-info RPC to also return a list of dictionaries containing the name
of each supported RPC, along with a boolean indicating whether or not
the command has been disabled by a guest administrator/distro.

Michael Roth abd6cf6d8e guest agent: add RPC blacklist command-line option
This adds a command-line option, -b/--blacklist, that accepts a
comma-seperated list of RPCs to disable, or prints a list of
available RPCs if passed "?".

In consequence this also adds general blacklisting and RPC listing
facilities to the new QMP dispatch/registry facilities, should the
QMP monitor ever have a need for such a thing.

Ideally, to avoid support/compatability issues in the future,
blacklisting guest agent functionality will be the exceptional
case, but we add the functionality here to handle guest administrators
with specific requirements.
