Cache and reuse the scraper HTTP client (#1855)
* Add Cookies directly to the request

Rather than maintaining a cookie jar on a one-shot HTTP client, maintain
the jar ourselves: make a new jar, then use it to select the right
cookies.

The cookies are set on the request rather than on the client. This will
retain the current behavior as we are always throwing the client away
after each use.

This patch enables the lifting of the http client as well over time.

* Introduce a cached scraper HTTP client

The scraper cache is augmented with an *http.Client. These are safe for
concurrent use, so the pointer can safely be passed around. Push this
into scraper configurations where applicable, next to the txnManagers.

When we issue a loadUrl request, do so on the cached *http.Client,
which will reuse existing idle connections in the client if any are
present.

* Set MaxIdleConnsPerHost. Closes #1850

We allow for up to 8 idle connections to a single host. This should
make concurrent operation toward the same host reuse connections, even
for sizeable concurrency.

The number isn't bumped excessively high. We should probably limit
concurrency toward a single site anyway, since we'll be able to overrun
a site with queries quite easily if we have many concurrent goroutines
issuing requests at the same time.

* Reinstate driverOptions / useCDP check

Use DeMorgan's laws to invert the logic and exit early. Fixes tests
breaking.

* Documentation fixup.

* Use the scraper http.Client when fetching images

Fold image fetchers onto the cached scraper http.Client as well. This
makes the scraper have a single http.Client cache for all its
operations.

Thread the client upwards to the relevant attachment points: either the
cache, or a stash_box instance, which is extended to include a pointer
to the client.

Style roughly follows that of txnManagers.

* Use the same http Client as the GraphQL client use

Rather than using http.DefaultClient, use the same client as the
GraphQL client use in the stash_box subsystem. This localizes the
client used in the subsystem into the constructing New.. call.

* Hoist HTTP client construction

Create a function for initializaing the HTTP Client we use. While here
hoist magic numbers into constants. Introduce a proper static redirect
error and use it in the client code as well.

* Reinstate printCookies

This is a debugging function, and it might still come in handy in the
future at some point.

* Nitpick comment.

* Minor tidy

Toward better context handling (#1835)
* Use the request context

The code uses context.Background() in a flow where there is a
http.Request. Use the requests context instead.

* Use a true context in the plugin example

Let AddTag/RemoveTag take a context and use that context throughout
the example.

* Avoid the use of context.Background

Prefer context.TODO over context.Background deep in the call chain.

This marks the site as something which we need to context-handle
later, and also makes it clear to the reader that the context is
sort-of temporary in the code base.

While here, be consistent in handling the `act` variable in each
branch of the if .. { .. } .. check.

* Prefer context.TODO over context.Background

For the different scraping operations here, there is a context
higher up the call chain, which we ought to use. Mark the call-sites
as TODO for now, so we can come back later on a sweep of which parts
can be context-lifted.

* Thread context upwards

Initialization requires context for transactions. Thread the context
upward the call chain.

At the intialization call, add a context.TODO since we can't break this
yet. The singleton assumption prevents us from pulling it up into main for
now.

* make tasks context-aware

Change the task interface to understand contexts.

Pass the context down in some of the branches where it is needed.

* Make QueryStashBoxScene context-aware

This call naturally sits inside the request-context. Use it.

* Introduce a context in the JS plugin code

This allows us to use a context for HTTP calls inside the system.

Mark the context with a TODO at top level for now.

* Nitpick error formatting

Use %v rather than %s for error interfaces.
Do not begin an error strong with a capital letter.

* Avoid the use of http.Get in FFMPEG download chain

Since http.Get has no context, it isn't possible to break out or have
policy induced. The call will block until the GET completes. Rewrite
to use a http Request and provide a context.

Thread the context through the call chain for now. provide
context.TODO() at the top level of the initialization chain.

* Make getRemoteCDPWSAddress aware of contexts

Eliminate a call to http.Get and replace it with a context-aware
variant.

Push the context upwards in the call chain, but plug it before the
scraper interface so we don't have to rewrite said interface yet.

Plugged with context.TODO()

* Scraper: make the getImage function context-aware

Use a context, and pass it upwards. Plug it with context.TODO()
up the chain before the rewrite gets too much out of hand for now.

Minor tweaks along the way, remove a call to context.Background()
deep in the call chain.

* Make NOTIFY request context-aware

The call sits inside a Request-handler. So it's natural to use the
requests context as the context for the outgoing HTTP request.

* Use a context in the url scraper code

We are sitting in code which has a context, so utilize it for the
request as well.

* Use a context when checking versions

When we check the version of stash on Github, use a context. Thread
the context up to the initialization routine of the HTTP/GraphQL
server and plug it with a context.TODO() for now.

This paves the way for providing a context to the HTTP server code in a
future patch.

* Make utils func ReadImage context-aware

In almost all of the cases, there is a context in the call chain which
is a natural use. This is true for all the GraphQL mutations.

The exception is in task_stash_box_tag, so plug that task with
context.TODO() for now.

* Make stash-box get context-aware

Thread a context through the call chain until we hit the Client API.
Plug it with context.TODO() there for now.

* Enable the noctx linter

The code is now free of any uncontexted HTTP request. This means we
pass the noctx linter, and we can enable it in the code base.

Remove unused (#1709)
* Remove stuff which isn't being used

Some fields, functions and structs aren't in use by the project. Remove
them for janitorial reasons.

* Remove more unused code

All of these functions are currently not in use. Clean up the code by
removal, since the version control has the code if need be.

* Remove unused functions

There's a large set of unused functions and variables in the code base.
Remove these, so it clearer what code to support going forward.

Dead code has been eliminated.

Where applicable, comment const-sections in tests, so reserved
identifiers are still known.

* Fix use-def of tsURL

The first def of tsURL doesn't matter because there's no use before
we hit the 2nd def.

* Remove dead code assignment

Setting logFile = "" is effectively dead code, because there's no use
of it later.

* Comment out found

The variable 'found' is dead in the function (because no post-process
action is following it). Comment it for now.

* Comment dead code in tests

These might provide hints as to what isn't covered at the moment.

* Dead code removal

In the case of constants where iota is involved, move the iota so it
matches the current key values.

This avoids problems with persistently stored key IDs.

Implement scraping movies by URL (#709)
* api/urlbuilders/movie: Auto format.

* graphql+pkg+ui: Implement scraping movies by URL.

This patch implements the missing required boilerplate for scraping
movies by URL, using performers and scenes as a reference.

Although this patch contains a big chunck of ground work for enabling
scraping movies by fragment, the feature would require additional
changes to be completely implemented and was not tested.

* graphql+pkg+ui: Scrape movie studio.

Extends and corrects the movie model for the ability to store and
dereference studio IDs with received studio string from the scraper.
This was done with Scenes as a reference. For simplicity the duplication
of having `ScrapedMovieStudio` and `ScrapedSceneStudio` was kept, which
should probably be refactored to be the same type in the model in the
future.

* ui/movies: Add movie scrape dialog.

Adds possibility to update existing movie entries with the URL scraper.

For this the MovieScrapeDialog.tsx was implemented with Performers and
Scenes as a reference. In addition DurationUtils needs to be called one
time for converting seconds from the model to the string that is
displayed in the component. This seemed the least intrusive to me as it
kept a ScrapeResult<string> type compatible with ScrapedInputGroupRow.
