library/*.m:
Specifically, delete any predicates and functions whose `pragma obsolete'
dates from 2018 or before. Keep the ones that were obsoleted
only this year or last year.
NEWS:
Announce the changes.

tests/tabling/mercury_java_parser_dead_proc_elim_bug2.m:
tests/valid/mercury_java_parser_follow_code_bug.m:
Replace references to predicates and functions that this diff deletes
with their suggested replacements.
In several test cases, bring the programming style up to date.
tests/hard_coded/shift_test.{m,exp}:
Most of this test case tested the now-deleted legacy shift operations.
Replace these with tests of their non-legacy versions, including
testing for the expected exceptions.
tests/hard_coded/shift_test.{m,exp}:
Don't pass --no-warn-obsolete when compiling shift_test.m anymore.
