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
