180f4d0929 FreeRTOS: Use C11 _Static_assert to verify static "dummy" structs at compile time
Includes a tweak to make Static_task_t equal size to TCB_t when using
MPU_WRAPPERS . Matches tskSTATIC_AND_DYNAMIC_ALLOCATION_POSSIBLE macro
in tasks.c. This isn't actually a bug (if static task allocation is off,
there is no use for Static_task_t), but it allows us to make consistent
compile-time checks that Static_task_t == TCB_t.

60f29236f6 Build system: Raise warning level
Default esp-idf builds now show -Wextra warnings (except for a few:
signed/unsigned comparison, unused parameters, old-style C declarations.)

CI building of examples runs with that level raised to -Werror, to catch
those changes going into the main repo.

ffeffcd315 Merge branch 'feature/crosscore_int' into 'master'
Add cross-core int to accelerate task being awoken from another CPU.

This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.

Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred

Old code:

CPU0->CPU0: 42986

CPU0->CPU1,: 2999

New code:

CPU0->CPU0: 42868

CPU0->CPU1: 62073

38c6256db9 Merge branch 'feature/wdts' into 'master'
Feature/wdts

This adds two watchdogs to  esp-idf:

- An interrupt watchdog. Kicks in if the FreeRTOS timer interupt on either the PRO_CPU or (when configured) the APP CPU isn't called for a configurable time. Panics, displaying which CPU caused the problem and the registers that may lead to the offending code.
- A task watchdog. A task has to feed it every once in a while. If not, it will print the name of the offending tasks, as well as the tasks currently running on both CPUs, and optionally panic.

Also adds a panic reason to the panic call, as well as fixes the panic code a bit.

0383bc8599 Merge branch 'workaround/pin_noaffinity_task_to_core_when_fpu_used' into 'master'
Workaround: Automatically pin no-cpu-affinity task to a core when FPU is used

FPU status at the moment does not migrate cleanly between cores, so tasks without affinity that happen to migrate across FPUs will run into problems. As a workaround, this modification will automatically pin the task to the current CPU when FPU activity is detected. If anything, it's better than getting all kinds of weird and wonderful FPU corruption issues...

01d17dd5f9 Backport the static allocation feature from FreeRTOS V9.0.0
This feature allows to use static buffers (or from a pool of memory which is not
controlled by FreeRTOS).
In order to reduce the impact of the changes, the static feature has only been added
to the queus (and in consequence to the semaphores and the mutexes) and the tasks.
The Timer task is always dynamically allocated and also the idle task(s), which in the
case of the ESP-IDF is ok, since we always need to have dynamic allocation enabled.

29c2e58c75 'Merge branch 'thread_local_storage_delete_callbacks' into 'master'
The thread-local-storage feature in FreeRTOS attaches an application-usable array of pointers to a thread control block. These pointers usually point to a structure the thread allocates. When a thread gets (voluntarily or involuntarily) destroyed, this memory can leak. This merge adds a matching second array of user-settable pointers to destructor routines. As soon as the task gets cleaned up (which happens in the idle thread), the destructors get called and the memory can be freed.
