Markus Armbruster 86bf13aea3 qapi: Replace ad hoc "since" documentation by member documentation
MemoryDeviceInfoKind, NetClientDriver, and GuestPanicAction mention
some members only in ad hoc since documentation.  The generated
documentation shows these members as "Not documented".

Replace by formal member documentation.

Add actual documentation text for the GuestPanicAction members, to
match existing member documentation there.  For the others, merely
move existing "since" information.

##
# @RunState:
#
# An enumeration of VM run states.
#
# @debug: QEMU is running on a debugger
#
# @finish-migrate: guest is paused to finish the migration process
#
# @inmigrate: guest is paused waiting for an incoming migration. Note
# that this state does not tell whether the machine will start at the
# end of the migration. This depends on the command-line -S option and
# any invocation of 'stop' or 'cont' that has happened since QEMU was
# started.
#
# @internal-error: An internal error that prevents further guest execution
# has occurred
#
# @io-error: the last IOP has failed and the device is configured to pause
# on I/O errors
#
# @paused: guest has been paused via the 'stop' command
#
# @postmigrate: guest is paused following a successful 'migrate'
#
# @prelaunch: QEMU was started with -S and guest has not started
#
# @restore-vm: guest is paused to restore VM state
#
# @running: guest is actively running
#
# @save-vm: guest is paused to save the VM state
#
# @shutdown: guest is shut down (and -no-shutdown is in use)
#
# @suspended: guest is suspended (ACPI S3)
#
# @watchdog: the watchdog action is configured to pause and has been triggered
#
# @guest-panicked: guest has been panicked as a result of guest OS panic
#
# @colo: guest is paused to save/restore VM state under colo checkpoint,
# VM can not get into this state unless colo capability is enabled
# for migration. (since 2.8)
