 revision="1e96c9214ef814260d1d66247b3ffbde7a019b45"
 FIX compile against PostgreSQL 16
 1) get_guc_variables() function now requires number variables reference.
 Change to not use this function at all and replace with find_option,
 which does much the same but with less code

 2) Abs function removed in PG16.  As noted in Discussion:
 https://www.postgresql.org/message-id/flat/4beb42b5-216b-
 bce8-d452-d924d5794c63%40enterprisedb.com
 We should be using C lib abs or fabs.  Replaced this left over use with
 fabs, which we are already using elsewhere

 Closes #5261 for PostGIS 3.4.0
