  Log Message:
  -----------
  rename abbreviation for section header index (SHI->SHN)

- matches ELF constants

  Changed paths:
    M src/backend/elfobj.c
    M src/backend/melf.h

  Log Message:
  -----------
  use extendend section header indices when exceeding SHN_LORESERVE

- overflowing section indices in symbol table are escaped
  (st_shndx field is set to SHN_XINDEX)

- additional .symtab_shndx section contains 32-bit section indices
  (contains zero entries for symbols that have a valid st_shndx value)

- overflowing section count in ELF header (e_shnum) is stored in the
  size field of the first section header (sh_size)

- insert dummy null sections to skip reserved section indices

  Changed paths:
    M src/backend/cdef.h

  Log Message:
  -----------
  use -1 as UNKNOWN segment index flag

- increases the maximum size of SegData from 32767 to INT_MAX

- the whole backend uses `int` as segment index
