inferior: Move initialization bits away from 'inferior-eval-with-store'.

* guix/inferior.scm (port->inferior): In the inferior, define
'cached-store-connection', 'store-protocol-error?', and
'store-protocol-error-message'.
(inferior-eval-with-store): Use them.

inferior: Inferior caches store connections.

Fixes <https://issues.guix.gnu.org/48007>.
Reported by Ricardo Wurmus <rekado@elephly.net>.

Previously, at each 'inferior-eval-with-store' call, the inferior would
create a new <store-connection> object with empty caches.  Consequently,
when repeatedly calling 'inferior-package-derivation', we would not
benefit from any caching and instead recompute all the derivations for
every package.  This patch fixes it by caching <store-connection>
objects in the inferior.

* guix/inferior.scm (port->inferior): Define '%store-table' in the inferior.
(inferior-eval-with-store): Cache store connections in %STORE-TABLE.
Remove now unneeded 'dynamic-wind' with 'close-port' call.

inferior: Keep the store bridge connected.

Previously, each 'inferior-eval-with-store' would lead the inferior to
connect to the named socket the parent is listening to.  With this
change, the connection is established once for all and reused
afterwards.

* guix/inferior.scm (<inferior>)[bridge-file-name]: Remove.
(open-bidirectional-pipe): New procedure.
(inferior-pipe): Use it instead of 'open-pipe*' and return two values.
(port->inferior): Adjust call to 'inferior'.
(open-inferior): Adjust to 'inferior-pipe' changes.
(close-inferior): Remove 'inferior-bridge-file-name' handling.
(open-store-bridge!): Switch back to 'call-with-temporary-directory'.
Define '%bridge-socket' in the inferior, connected to the caller.
(proxy): Change first argument to be an inferior.  Add 'reponse-port'
and call to 'drain-input'.  Pass 'reponse-port' to 'select' and use it
as a loop termination clause.
(inferior-eval-with-store): Remove 'socket' and 'connect' calls from the
inferior code, and use '%bridge-socket' instead.

inferior: Create the store proxy listening socket only once.

Previously, each 'inferior-eval-with-store' call would have the calling
process create a temporary directory with a listening socket in there.
Now that listening socket is created once and reused in subsequent
calls.

* guix/inferior.scm (<inferior>)[bridge-file-name, bridge-socket]: New
fields.
(port->inferior): Adjust accordingly.
(close-inferior): Close 'inferior-bridge-socket' and delete
'inferior-bridge-file-name' if set.
(open-store-bridge!, ensure-store-bridge!): New procedures.
(inferior-eval-with-store): Use them.
