    vendor/awk: upgrade from 20121220 to 20200612
    
    Summary of notable changes:
    
    - fixed buffer overflow in error reporting
    - OFS value used to rebuild the record was incorrect
    - add POSIX standard %a and %A to supported formats
    - decrementing NF did not change $0
    - unary plus on a string constant returned the string
    - avoid undefined behaviour when using ctype(3) functions in relex()
    - make getline handle numeric strings
    - added support for POSIX-standard interval expressions in regexps
    - use of random(3) as the random number generator
    - support POSIX-specified C-style escape sequences "\a" and "\v" in
      command line arguments and regular expressions
    - fix various array / memory overruns
    - import code from NetBSD awk that implements RS as a regular expression
    - add an optimization for string concatenation
    - fix a bug whereby a{0,3} could match four a's
    - input/output errors on closing files are now fatal instead of mere
      warnings
    - if POSIXLY_CORRECT is set in the environment, then sub and gsub use
      POSIX rules for multiple backslashes
    - it's no longer necessary to use the -y flag to bison
    - backslash continuation inside strings removes the newline
    - avoid any spurious errors left over from previous calls
