Description

It is currently quite easy to misconfigure the SMP EDF scheduler so that not enough memory is reserved for the scheduler data structures. The only feedback to the user from these configuration errors is a memory corruption. Improve the configuration means or at least issue a fatal error.

config: Improve EDF SMP scheduler configuration

Use CONFIGURE_MAXIMUM_PROCESSORS to configure the EDF SMP scheduler
context. This avoids hard to debug configuration errors resulting in
memory corruptions.

Close #3815.
