This updates the jMAVSim submodule which includes a fix for HITL.
In order to fix HITL, a CLI argument `-lockstep` was required to enable
lockstep. This has now been added to the command in jmavsim_run.sh.
By using the uORB::Subscription API we use a separate subscription
rather than `orb_copy` on the existing file descriptor used in
sensors through `px4_poll`.
This fixes a very peculiar problem that we observed in SITL in CI for
fixedwing. The events were as follows:
1. `sensors` does `px4_poll` on the gyro topic (as normal), and gets
the latest sample using `orb_copy`.
2. A parameter update happens when the mag is initialized and triggers
`VotedSensorsUpdate::parameters_update()` where `orb_copy` happens
before the main loop in `sensors` has started a `px4_poll`.
3. `sensors` now does the `px4_poll`, however waits indefinitely because
it has already copied the latest sample.
Also, the `px4_poll` will never time out because in lockstep the
simulator waits for the next actuator control message which it never
gets and therefore it never sends the next sensor message with a new
timestamp to advance the time.
This only happens for fixedwing because there is only one "uORB path"
through the system unlike for multicopter where a gyro sample can get
picked up by either `sensors` or directly `mc_att_control`, so the
system can survive if `sensors` has "drops".
Rate changes were doing an asynchronous register reload via the EGR_UG. This could extend a PWM pulse up to 2X.
This fix removes the asynchronous update. The net effect is the the rate change will occur on the next counter expiration. The worst case is the rate change is delayed by 20 Ms.

changed: "Mission rejected: land start required."
to: "Mission rejected: landing pattern required."
This new message is more clear to the average user. When using RTL_TYPE = 1, mission feasibility checker adds the requirement of a landing sequence beginning with a MAV_CMD_DO_LAND_START and ending with a MAV_CMD_NAV_LAND with at least 1 other waypoint prior to the land waypoint. The warning message "Mission rejected: land start required." is a common warning to trigger whenever the mission is blank or the mission is uploaded without a landing pattern. The wording in this message confusing to the average user as they usually do not know the inner workings of the "landing pattern" that their planning software helps them make (e.g. Qgroundcontrol). The only users who would know what a "Do_Land_Start" mission item is are advanced users already and this new message should work equally well for them as well as the non-advanced user.
The previous code used the numeric baudrate as the speed argument
for cfsetispeed() and cfsetospeed(). This works in OSX and NuttX,
but is not portable.
This fix introduces a new method to convert baudrate to speed using
constants such as B115200.
