  the different kinds of jumper available

Constants

• LONG_JUMPER_LEN
  the length of a long jumper.
• MAX_JUMPER_LEN
  the maximum length of a jumper of any kind.
• MAX_MAYBE_RELOCATED_INSN_LEN
  the maximum length of an instruction that is either relocated or the original instruction
• MAX_RELOCATED_INSNS_AMOUNT
  the maximum amount of instructions that we may need to relocate when hooking a fn.
• MAX_RELOCATED_INSNS_LEN

  determines the best jumper kind to use in a specific case.
• determine_best_jumper_kind_and_build
  determines the best jumper kind to use in a specific case and builds it.
• gen_hook_info
  generates information needed to hook the given fn.
• relocate_fn_start
  relocate the instructions at the start of the fn so that we can put them in a different memory address and they will still work fine.
