* Factor out the default `MultiCommand` behavior
All the `MultiCommand`s had (nearly) the same behavior when called
without a subcommand.
Factor out this behavior into the `NixMultiCommand` class.
* Display the list of available subcommands when none is specified
Whenever a user runs a command that excepts a subcommand, add the list
of available subcommands to the error message.
* Print the multi-command lists as Markdown lists
This takes more screen real estate, but is also much more readable than
a comma-separated list
Per the instruction in the manual, we want to run configure in a
different directory so that we can configure + build for multiple
platforms. That means `config.h` will be in the build directory. This is
just like `Makefile.config`, which already is used with
`$(buildprefix)`.
without knowing a lot of context, it's not clear who "we" are in that
text. I'm also strongly opposed to adding procedural notes into
a reference manual; it just won't age well.
this change leaves a factual description of the experimental feature and
its purpose.
The problem was since switching to use libgit2, we had a package in our
closure (`http-parser`) that was always trying to build as a shared
object.

Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:
- We have to be careful that wildcards don't end up with tests being
built as part of Nix proper, or test headers being installed as part
of Nix proper.
- Tests in libraries but not executables is not right:
- It means each executable runs the previous unit tests again, because
it needs the libraries.
- It doesn't work right on Windows, which doesn't want you to load a
DLL just for the side global variable . It could be made to work
with the dlopen equivalent, but that's gross!
This reorg solves these problems.
There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.

This makes for more useful manual table of contents, that displays the
information at a glance.
The `nix help-stores` command is kept as-is, even though it will show up
in the manual with the same information as these pages due to the way it
is written as a "`--help`-style" command. Deciding what to do with that
command is left for a later PR.
This change also lists all store types at the top of the respective overview page.

this focuses on `nix-shell -p` and refers to search.nixos.org for
package search, which is currently the easiest and most effective way to
find program names.
- put the highlight box around all the relevant instructions
- simplify the wording
- make the link more prominent by using the whole phrase for the link text
