lib/sh/util.sh: use simpler `if can_log; then indent; fi` instead of `can_log && indent || true`. however, the `&& indent || true` syntax is still required in aliases such as echo_func which need to allow prefixing the command with a wrapper command or kw param assignments.

inputs/GBIF/raw_occurrence_record/run: dynamically generate herbaria_filter.csv_ from herbaria.ih in new target herbaria_filter.csv_/make()

inputs/GBIF/raw_occurrence_record/run: store the herbaria filter in a MySQL table loaded from a CSV instead of getting it from a hardcoded list of IN (...) values

lib/sh/db.sh: added truncate()

lib/sh/make.sh: set_make_vars: set $target_stem

lib/sh/db.sh: added mysql_import()

lib/sh/db.sh: removed no longer used mk_esc_name()

lib/runscripts/table.run: don't mk_esc_name schema, table because these will be mk_esc_name'd by functions that use them

lib/sh/local.sh: psql(): use $schema_esc, $table_esc instead of just putting $schema, $table in ""

lib/sh/db.sh: mk_esc_name_alias(): don't overwrite an already-defined $*_esc, to allow the user to provide an already-escaped value (such as a schema-qualified table) directly
