Bad code in ~~~qsciencespinbox~~~ -e- actually in Qt... according to our source file:

/**
 * Code copied from http://www.matthiaspospiech.de/blog/2009/01/03/qt-spinbox-widget-with-scientific-notation/
 */

-e- Fixed in qt/qtbase@342bb5b
So, either need to wait for Qt 5.9.5, or go to Qt 5.10/11... or I need to build my own patched Qt 5.9.2. 😢

Bumped to Ludicrous-- can't do tools changes this late in inconceivable cycle (want to ship)

It looks like we have a few dubious memcpy's too but should wait for upstream tools to be ready for 8.1 to hunt 'em.

I can still build with clang (6.0.0) without any hax (luckily we don't do -Werror there).

* pios_bmp280: prevent i2c/spi r/w peeking at globals

* pios_bmp280: formatting

* pios_bmp280: probe without allocating structures

* pios_i2c: check bus clear before completion of init

* revolution: simplify i2c init / clone logic

* revolution: probe bmp280 on clones

* GCS:UAVTalk: Don't check backlog for QFileDevices

It has quite a large buffer, larger than our backlog limit for telemetry,
thus it always got blocked by our internal buffer size check and stopped
working.

* disable '-Werror' on linux too. Fix issue d-ronin#2205

* UAVOMSPBridge: Send ! instead of | for MSP error

This was raised in a BLHeli issue[6]. The MSP code sends a message with `|` in
the case of an unknown message type[1]. That is consistent with the Multiwii
protocol spec[2], but differs from the actual multiwii/baseflight/betaflight
implementations, which send `!`[3][4][5]. Since we're on our own here, I think
we need to disregard the original protocol spec.
