Benjamin Walsh f955476559 kernel/arch: optimize memory use of some thread fields ... Some thread fields were 32-bit wide, when they are not even close to using that full range of values. They are instead changed to 8-bit fields. - prio can fit in one byte, limiting the priorities range to -128 to 127 - recursive scheduler locking can be limited to 255; a rollover results most probably from a logic error - flags are split into execution flags and thread states; 8 bits is enough for each of them currently, with at worst two states and four flags to spare (on x86, on other archs, there are six flags to spare) Doing this saves 8 bytes per stack. It also sets up an incoming enhancement when checking if the current thread is preemptible on interrupt exit.
