0baee6f82b GCS_MAVLINK: avoid pushing partial RC_CHANNEL message into uart
In the case we do not send RC_CHANNELS_RAW, we will not check to see if
RC_CHANNELS will fit.  RC_CHANNELS is larger than RC_CHANNELS_RAW, so the
check in the caller is insufficient.

AP_RollController's get_servo_out function does not return an elevator deflection as was previously described in the function comments.

f668d0dc57 GCS_MAVLink: enhance TIMESYNC handling
GCS_MAVLink: use de-jittered timestamp for our timesync responses

GCS_MAVLink: periodically send timesync request packets

Currently no use is made of the result of these requests, however,
having the result present in telemetry logs will be useful data.

88dc17fe6e AP_HAL_Linux: Storage: fix initialization
Use init() to lazily create/open storage directory and keep fd open
afterwards. This avoids duplicate code opening the storage in several
places.

1f3b7b5687 AP_HAL_Linux: Storage: fix writing garbage while creating file
By the time we create the storage we hadn't still initialized the
buffer. Remove the writes during storage creation since ftruncate() will
take care of the file size aspect and MAX storage write chunk is taken
care by Linux according to the media/fs that is there.

1e7ad72909 AP_HAL: use default storage for more boards
Boards from Emlid, Erle Robotics and BBB-like ones were agreed to be
changed #7100. Here I'm also change some more, just because they appear
to be using the old default just because of copy and paste. We can
always revert back if we get complains and it seems something trivial.
Almost all boards now are using the the default path for logs, terrain
and params, except those that have restrictions to do so, like ones
using custom distros.

a7fbfe7767 AR_AttitudeControl: caller provides dt instead of calculated internally
This allows the vehicle's main loop rate to be used instead of an internally calculated dt which suffers from jitter
