specification of the bytecode file format

bytecode file:
  <file header>
  <section 0>
  ...
  <section sec_cnt-1>

file header:
  "NIPS v1a"
  sec_cnt: uint16_t, big-endian, number of sections in file

section:
  sec_type: 4 uint8_t, ASCII, type of section
  sec_sz: uint32_t, big-endian, size of section's content
  section content: sec_sz uint8_t

section: module
  sec_type: "mod "
  sec_sz: uint32_t, big-endian, size of module section's content
  <string module_name>
  part_cnt: uint16_t, big-endian, number of parts in module
  <part 0>
  ...
  <part part_cnt-1>

part
  part_type: 4 uint8_t, ASCII, type of part
  part_sz: uint32_t, big-endian, size of part's content
  part content: part_sz uint8_t

part: module flags
  part_type: "modf"
  part_sz: uint32_t, big-endian, always 4
  mod_flags: uint32_t, big-endian, some flags describing properties of the module
             0x00000001 = monitor exists

part: bytecode
  part_type: "bc  "
  part_sz: uint32_t, big-endian, size of bytecode
  bytecode: part_sz uint8_t, the bytecode

part: flag table
  part_type: "flag"
  part_sz: uint32_t, big-endian, size of entire flag table
  flag_cnt: uint16_t, big-endian, number of flag entries in this table
            the entries in this table have to be sorted ascending by their addresses
  <flag 0>
  ...
  <flag flag_cnt-1>

flag:
  addr: uint32_t, big-endian, address for which flags are given
  flags: uint32_t, the flags for this address
                   0x00000001 = progress state
                   0x00000002 = accept state

part: string table
  part_type: "str "
  part_sz: uint32_t, big-endian, size of entire string table
  str_cnt: uint16_t, big-endian, number of strings in this table
  <string 0>
  ...
  <string str_cnt-1>

string:
  str_sz: uint16_t, big-endian, size of string (including terminating zero)
  str: str_sz uint8_t, ASCII, zero-terminated string

part: source location table
  part_type: "sloc"
  part_sz: uint32_t, big-endian, size of entire source location table
  sloc_cnt: uint16_t, big-endian, number of source locations in this table

srcloc:
  addr: uint32_t, big-endian, address whose source location is to be specified
  line: uint32_t, big-endian, line number
  col: uint32_t, big-endian, column number

part: structure information table
  part_type: "stin"
  part_sz: uint32_t, big-endian, size of entire structure information table
  stin_cnt: uint16_t, big-endian, number of structure information entries in this table
            the entries in this table have to be sorted ascending by their addresses
  <strinf 0>
  ...
  <strinf stin_cnt-1>

strinf:
  addr: uint32_t, big-endian, address for which some structure information is given
  code: uint8_t, 0x00 = start of some structure, 0x01 = end of some structure, 0x02 = middle in some structure
