schemas/vegbien.ERD.mwb: Synced with schema

bin/map: Call sys.stdout.flush() after every call to sys.stdout.write() to avoid interleaved stdout/stderr output due to stdout buffering

bin/map: Call sys.stdout.flush() after every call to sys.stdout.write() to avoid interleaved stdout/stderr output due to stdout buffering

schemas/vegbien.sql: *_unique_datasource UNIQUE INDEXes: Removed COALESCE from datasource_id and datasource_id IS NOT NULL filter, because datasource_id is now always NOT NULL

schemas/filter_ERD.csv: Removed AUTO_INCREMENT because that is not added to any other tables

Regenerated schemas/vegbien.my.sql

schemas/vegbien.sql: specimenreplicate: Inherit datasource_id from taxonoccurrence instead of defining it independently

xml_func.py: Removed no longer needed local XML functions that have been translated to SQL functions

input.Makefile: Testing: Removed VegBIEN.%.xml test because the import.%.xml test output includes the template tree that it's inserting, so there is no need to generate the XML tree in a separate test. This will also remove the need to maintain local XML functions that have already been translated to DB functions for the sole purpose of this automated test.

schemas/vegbien.sql: Made datasource_id required on every table that has it, to trigger the automatic population of it by sql_io.put_table()'s col_defaults
