Message:

sysinfo overhaul

• cleanup (nicer data structures, use of SLAB allocator)
• add support for storing arbitrary binary data
• properly reimplement non-constant values (generated by functions)
• add support for non-constant subtrees (generated by functions)
• syscall ABI change, libc API change
• reflect changes in user code

libc: task_spawn() can now return error code

• reflect change in user code, print error strings after failed task_spawn()

uspace cleanup

• more use of string and other constants
• more use of str_error()
• unify error reporting in init
