Remove a _lot_ of parser/(*parser*) function arguments

Remove a _lot_ of parser/(*parser*) function arguments

This is a bit uglified because it is likely going to become part of
version 2.19.23 or later, so this proactively bumps the version.  The
final committed version will just be what is in master at that time.


Contains the following commits in reverse order:

Bump version for the sake of regtesting


Fix the rest of removal of parser/(*parser*) manually


Call all *-handler functions without parser argument


Let ly:parse-error and others work with %parser fluid


Run scripts/auxiliar/update-with-convert-ly.sh, convert scm as well
