Víctor Mayoral Vilches 9f5b4ffca4 AP_HAL_Linux_Class: Correct deadlock, and infinite loop in setup()
(credit to Mitch Miers <mmiers@mmiers.com>):

setup() is attempting to initialize the hardware, and while doing so
is attempting to output some text via the console (and maybe mavlink
data).  The problem is, the output isn't going to complete once a
write buffer is full, because LinuxUARTDriver::_timer_tick() doesn't
perform work until _initialized is true.  So, what happens is,
setup() (and subroutines) call LinuxUARTDriver::_write(uint8_t c),
which loops waiting for buffer space to become available (once the
write buffer is full).  The buffer never gets space, because the
UART thread is waiting for initialization to complete before it
will write out data and drain the buffer, but that doesn't happen
until setup() returns (see AP_HAL_Linux_main.h).

Víctor Mayoral Vilches 27ebf790e2 AP_HAL_Linux: Add support for SPIDevice_MPU9250
The Invensense MPU9250 SPI device is connected to
SPI1, thereby SPIDriver class should return the
corresponding device.

Andrew Tridgell b99ae63cbb HAL_Linux: more generic fix for scheduler issues in example sketches
this ensures drivers can run

Andrew Tridgell 6eee2421cc AP_HAL: removed RCInput valid_channels() and added new_input() and num_channels()
the valid_channels() method was inconsistently implemented between
boards, and served two quite different purposes. It is clearer as two
functions
