Revamp task creation so that there isn't a predefined maximum number of tasks

Possible Options

• Users can declare the required variables (thread struct) and pass in a pointer to that struct
• Dynamically allocate memory for the thread struct
• Both of the above options, similar to FreeRTOS. They'd both store pointers to the thread structs in an array anyways

I think the way FreeRTOS does it is with a static array where the number of elements equals the number of possible priorities. Then, each element in the array points to a linked list.

We could use a statically allocated linked list where the user statically allocates the memory, but we store the previous and next thread in each osthread_t struct. We need to determine how this would impact our current algorithms and their time complexity.
