This patch is updating all soft-fp from glibc, most changes are
copyright years update, and changes other than years update are list
bellow, this patch has been tested with riscv32-elf(rv32imac),
riscv64-elf(rv64imac) and nds32le-elf(v3), didn't introduce new test
fail:

soft-fp/op-4.h
  - soft-fp: Use temporary variable in FP_FRAC_SUB_3/FP_FRAC_SUB_4
    - ff48ea6787526d7e669af93ce2681b911d39675c
soft-fp/op-8.h
  - soft-fp: Add implementation for 128 bit self-contained
    - af1d5782c1e3a635fdd13d6688be64de7759857c
