safeweb: allow object-src: self in CSP (#11782)
This change is safe (self is still safe, by
definition), and makes the code match the comment.

safeweb: move http.Serve for HTTP redirects into lib (#11592)
Refactor the interaction between caller/library when establishing the
HTTP to HTTPS redirects by moving the call to http.Serve into safeweb.
This makes linting for other uses of http.Serve easier without having to
account for false positives created by the old interface.

safeweb: detect mux handler conflicts (#11562)
When both muxes match, and one of them is a wildcard "/" pattern (which
is common in browser muxes), choose the more specific pattern.
If both are non-wildcard matches, there is a pattern overlap, so return
an error.

safeweb: add opt-in inline style CSP toggle (#11551)
Allow the use of inline styles with safeweb via an opt-in configuration
item. This will append `style-src "self" "unsafe-inline"` to the default
CSP. The `style-src` directive will be used in lieu of the fallback
`default-src "self"` directive.

safeweb: return http.Handler from safeweb.RedirectHTTP (#11538)
Updates #cleanup

Change the return type of the safeweb.RedirectHTTP method to a handler
that can be passed directly to http.Serve without any http.HandlerFunc
wrapping necessary.

safeweb: init (#11467)
Updates https://github.com/tailscale/corp/issues/8027

Safeweb is a wrapper around http.Server & tsnet that encodes some
application security defaults.

Safeweb asks developers to split their HTTP routes into two
http.ServeMuxs for serving browser and API-facing endpoints
repsectively. It then wraps these HTTP routes with the
context-appropriate security controls.

safeweb.Server#Serve will serve the HTTP muxes over the provided
listener. Caller are responsible for creating and tearing down their
application's listeners. Applications being served over HTTPS that wish
to implement HTTP redirects can use the Server#HTTPRedirect handler to
do so.
