225e4c0e76 kernel: greatly simplify syscall handlers 
We now have macros which should significantly reduce the amount of
boilerplate involved with defining system call handlers.

- Macros which define the proper prototype based on number of arguments
- "SIMPLE" variants which create handlers that don't need anything
  other than object verification

37ff5a9bc5 kernel: system call handler cleanup 
Use new _SYSCALL_OBJ/_SYSCALL_OBJ_INIT macros.

Use new _SYSCALL_MEMORY_READ/_SYSCALL_MEMORY_WRITE macros.

Some non-obvious checks changed to use _SYSCALL_VERIFY_MSG.
