This commit introduces a very light-weight and lock-less scheduling of the Controller's deferred function calls called the Mayfly. Earlier work implementation used in the Controller had an O(n) to schedule a function in a linked list that used IRQ lock during modification of the linked list in the Controller's ISR executions. Mayfly is a compile time configurable matrix of queues where an execution context-safe queue exists between two execution context, one being the caller and the second being the callee. Callee(s) are run in a software interrupt but can also be run in an OS thread. There are minor clean ups too in this commit related to folder structure.
