`__main_thread_stack_base__` and `__main_thread_stack_end__` are
variables whose address is defined to be the corresponding part of the
stack. These are declared as `extern stkalign_t` in ChibiOS code, and
being declared as `extern uint32_t` in ArduPilot code creates a warning
at link time when using LTO. Correct the declaration to eliminate this
warning.
Also update `__main_stack_base__` and `__main_stack_end__` which don't
currently trigger this warning but serve similar purposes and so might
in the future.
The hardware expects an alignment of `stkalign_t` (which is 8 bytes) and
the linker script defines the variable values with this alignment as
well, so this is safe.
No code size or functional change.

this fixes an issue where when you lose R/C input on IOMCU that you
may not regain it when R/C comes back.
The issue stems from us still processing the DSM uart when we are
using the SD3 "SBUS" uart for RC input, and still doing the switch of
the SD3 config every 2 seconds.
When we are not searching for a new protocol we should not be changing
UART config
if the IOMCU resets twice in quick succession then the code that
restores the safety state while flying can fail, leading to the
aircraft trying to continue flying with safety on
This results from two issues:
- a race in handling the last_safety_off variable
- the fact that plane sets the soft_armed state based on safety state
