[PATCH V4 0/3] Add osnoise/options options

[Daniel Bristot de Oliveira]

After adding the osnoise/options file, a set of on/off options
came to my mind, most based on discussions while debugging problems
with Juri and Clark.

The PANIC_ON_STOP option facilitates the vmcore generation to aid
in the latency analysis using a crash dump.

The OSNOISE_PREEMPT_DISABLE and OSNOISE_IRQ_DISABLE options refine
the type of noise that the osnoise tracer detects, allowing the
tool to measure only IRQ-related noise, or NMI/HW-related noise,
respectively.

Each patch has a description of the options and the last patch
documents them in the osnoise documentation file.
