lib/sh/db.sh: mk_select: renamed to mk_select_var since it actually sets a var in the local context rather than returning a query

inputs/GBIF/raw_occurrence_record/run: herbaria_filter.table/make(): specify the different parts used to create the table in an array

inputs/GBIF/raw_occurrence_record/run: renamed herbaria_filter.csv_ to herbaria_filter.ih.csv_ to allow for other tables that get combined into herbaria_filter

bugfix: lib/sh/db.sh: mk_select: ensure newline before LIMIT clause, in case caller provided custom query which did not have trailing newline

bugfix: mappings/VegCore-VegBIEN.csv: place.geovalid: added missing /1 after _alt

bugfix: lib/sql.py: parse_exception(): typed_name_re: added back matching of names without "", since these are used by some error messages (ones that contain () after the function name)

bugfix: lib/sql.py: parse_exception(): typed_name_re: need to allow " within the matched name, since there are now "" around the entire identifer that was passed to Postgres, which may itself include " . always require "" around the matched name, to ensure that the whole name is matched by .+? e.g. when followed by () for a function call. the version of Postgres we currently use apparently no longer has error messages without the "", so we don't need a separate regexp for quoted and unquoted names.

lib/sh/db.sh: mysql_import(): automatically ensure the table is empty (i.e. using truncate()), unless append=1 is specified. extra calls to truncate() now that this happens automatically have also been removed.

bin/map: by_col: ensure verbosity is at least 2 in live mode (using new ints.set_min() instead of max() for clarity). documented that live column-based import MUST be run with verbosity 2+ (3 preferred) to provide debugging information for often-complex errors. without this, debugging is effectively impossible.

added lib/ints.py with renamings of max()->set_*min*(), min()->set_*max*() for easier understandability of the set-ceiling/set-floor use cases of min()/max()
