tests: Cleanup access to internal variables 
Replace direct accesses to sched_active_thread and sched_active_pid with
the helper functions thread_getpid() and thread_get_active(). This serves
two purposes:

1. It makes accidental writes to those variable from outside core less likely.
2. Casting off the volatile qualifier is now well contained to those two
   functions

Expected result

You should be presented with the RIOT shell, providing you with commands to initialize a board as master or slave, and to send and receive data via SPI.

Background

Test for the low-level SPI driver.

Default SPI CS pin

To overwrite the optional default cs pin CFLAGS can be used:

CFLAGS="-DDEFAULT_SPI_CS_PORT=<my_port_int> -DDEFAULT_SPI_CS_PIN=<my_pin_int>" BOARD=<my_board> make flash term
