use yet even more bin/jval-wrapper.sh instead of direct grep of JSON files

We use the `bin/jval-wrapper.sh` tool to obtain information from JSON
files instead of attempting using a "GROSS HACK" that involved using
`grep(1)` (and friends) as those "GROSS HACK"s assumed that the layout of
the JSON was canonical.  The `bin/jval-wrapper.sh` tool is able to deal
with various layouts of JSON including non-canonical layouts.  Moreover,
by using the `bin/jval-wrapper.sh` tool we greatly reduce the places in
bin tools that contain "GROSS HACK"s.

Adjusted `bin/gen-status.sh` to use `bin/jval-wrapper.sh`.

Changed `bin/gen-status.sh` VERSION from "1.5.8 2024-08-05"
to "1.6 2024-08-17".

Performed `make gen_status` to test the above under macOS.

Adjusted `bin/gen-years.sh` to use `bin/jval-wrapper.sh`.

Changed `bin/gen-years.sh` VERSION from "1.3.7 2024-08-05"
to "1.4 2024-08-17".

Performed `make gen_years` to test the above under macOS.

Adjusted `bin/output-index-author.sh` to use `bin/jval-wrapper.sh`.

Changed `bin/output-index-author.sh` VERSION from "1.7.3 2024-08-05"
to "1.8 2024-08-17".

Performed `make entry_index` to test the above under macOS.

Added `make quick_year_index` to generate year level index.html files
when year level `YYYY/README.md` is newer.

The `make quick_www` calls `quick_year_index` instead of `make gen_year_index`.

The `bin` directory is now sat as `BIN_PATH=$TOPDIR/bin`, where
`$TOPDIR` is determined by top of the git repo (as determined by
the command: `git rev-parse --is-inside-work-tree`) and potentially
modified by `-d topdir`.  After `cd $TOPDIR`, we set `BIN_DIR=bin`.

All tools from this repo are now assumed to under "$BIN_DIR".  Removed
command like options such as `-T md2html.sh`, and `-p tool` that used
to be able to change the location of a `bin` tool.

Changed `bin/gen-authors.sh` VERSION from "1.11 2024-08-13"
to "1.12 2024-08-18".

Changed `bin/gen-location.sh` VERSION from "1.5 2024-08-17"
to "1.6 2024-08-18".

Changed `bin/readme2index.sh` VERSION from "1.2.7 2024-08-05"
to "1.3 2024-08-17".

Modified `bin/all-run.sh` to use the `bin` directory mechanism.
Modified `bin/all-years.sh` to use the `bin` directory mechanism.
Modified `bin/gen-other-html.sh` to use the `bin` directory mechanism.
Modified `bin/gen-year-index.sh` to use the `bin` directory mechanism.
Modified `bin/md2html.sh` to use the `bin` directory mechanism.
Modified `bin/quick-readme2index.sh` to use the `bin` directory mechanism.
Modified `bin/readme2index.sh` to use the `bin` directory mechanism.

Changed `bin/all-run.sh` VERSION from "1.3.6 2024-08-05"
to "1.4 2024-08-17".

Changed `bin/all-years.sh` VERSION from "1.0.5 2024-08-05"
to "1.1 2024-08-17".

Changed `bin/gen-other-html.sh` VERSION from "1.3 2024-08-11"
to "1.4 2024-08-17".

Changed `bin/gen-year-index.sh` VERSION from "1.1.2 2024-08-05"
to "1.2 2024-08-17".

Changed `bin/quick-readme2index.sh` VERSION from "1.1.7 2024-08-05"
to "1.2 2024-08-17".

Changed `bin/md2html.sh` VERSION from "1.5.5 2024-08-05"
to "1.6 2024-08-17".

Added some whitespace in the form of empty lines to tools.

Made checks for tools under `bin` directory more consistent.

When using `-Q` (quick mode) and the prerequisite files are newer,
we force the target to be touched so that a later run will not
have to build the target HTML file.

Performed `make quick_www` to test the above under macOS.

Performed `make www` to test the above under macOS.
