major code revision

  • replace spinlocks taken with interrupts disabled with irq_spinlocks
  • change spacing (not indendation) to be tab-size independent
  • use unsigned integer types where appropriate (especially bit flags)
  • visual separation
  • remove argument names in function prototypes
  • string changes
  • correct some formating directives
  • replace various cryptic single-character variables (t, a, m, c, b, etc.) with proper identifiers (thread, task, timeout, as, itm, itc, etc.)
  • unify some assembler constructs
  • unused page table levels are now optimized out in compile time
  • replace several ints (with boolean semantics) with bools
  • use specifically sized types instead of generic types where appropriate (size_t, uint32_t, btree_key_t)
  • improve comments
  • split asserts with conjuction into multiple independent asserts
  • Property mode set to 100644
