inputs/GBIF/raw_occurrence_record/run: table.tsv/make(): moved making of table.tsv.md5 to separate function

lib/sh/util.sh: $log_fd: indicated that this is only initially stderr (however, the new port will just use stderr if it's not redirected separately)

lib/sh/util.sh: verbosities: 3: added that this includes values of kw params

lib/sh/util.sh: logging: added description of the verbosities available, including what each one does and what it's useful for:

1. verbosities:
2. 0: just print errors. useful for cron jobs.
3. 1: also external commands run. useful for running at the command line....

lib/sh/util.sh: command__set_fds(): echo the >& line at a higher log_level, because this information (i.e. which fd is used by the command for logging) is primarily for debugging and should not normally be printed

inputs/GBIF/raw_occurrence_record/run: table.tsv/make(): also add md5 sum for table.tsv

inputs/GBIF/raw_occurrence_record/run: table.tsv/make(): added back filter kw args, which had gotten deleted in a commit without update (although actually, svn should not allow a commit without update, so the working copy may have gotten corrupted)

lib/runscripts/table.run: input_make(): added $silent flag which turns on make's --silent option

lib/sh/make.sh: set_make_vars: usage: added "use $target" to indicate that vars are made available by this alias

lib/sh/make.sh: inline_make(): take the script stdin from caller-provided stdin and get make's stdin from global stdin, so that the caller can just use <<'EOF' rather than having to include a specific fd before the <<
