Message:

cleanup thread_create() and thread_t structure

• remove 'flag' bitfield from thread_t, use individual boolean flags (can be optimized later on by adding : 1)
• use an enum for call flags, add THREAD_FLAG_NONE
• remove the 'uncounted' argument in favour of a call flag
• introduce thread_wire() to setup wired threads
