Rework the apply confirmation mechanism to be session agnostic in order to
circumvent cross domain restrictions which prevent the JS code from issuing
apply confirm requests in some cases, e.g. when changing the LAN IP.
Confirmation calls may now be done from unauthenticated pages, as long as a
matching confirmation token is sent along with the request.
The reasoning behind this is that there is little security impact in
confirming pending apply sessions, especially since those sessions can only
be initiated while being authenticated.
After this change, LuCI will now launch a confirmation process on every
rendered page when a rollback is pending. The confirmation will happen
regardless of whether the user is logged in or not, or if the current page
is a CBI form or static template.
A confirmation request now also requires a random one-time token which is
rendered along with the confirmation JavaScript code in order to succeed.
This token is not meant to provide security but to ensure that the confirm
was triggered from an interactive browser session and not some background
HTTP requests that happened to end up in the admin ui.
As a consequence, the different apply/confirm/rollback code paths in CBI
maps and the UCI change/revert pages have been consolidated into one common
implementation residing in the common global theme agnostic footer template.

Switch to rpcd based uci apply/rollback workflow which helps to avoid soft-
bricking devices by requiring an explicit confirmation call after config
apply.
When a user now clicks "Save & Apply", LuCI first issues a call to uci apply
which commits and reloads configuration, then goes into a polling countdown
mode where it repeatedly attempts to call uci confirm.
If the committed configuration is sane, the confirm call will go through and
cancel rpcd's pending rollback timer.
If the configuration change leads to a loss of connectivity (e.g. due to bad
firewall rules or similar), the rollback mechanism will kick in after the
timeout and revert configuration files and pending changes to the pre-apply
state.
In order to cover such rare cases where a lost of connectivity is expected
and desired, the user is offered an "unchecked" apply option after timing
out, which allows committing and applying the changes anyway, without the
extra safety checks.
As a consequence of this change, the luci-reload mechanism is now completely
unsused since rpcd uses ubus config reload signals to reload affected
services, which means that only procd-enabled services will receive proper
reload treatment with the new workflow.

Instead of passing the full LuCI request url, pass the relative resolved
request path instead and filter the received value through the lookup()
dispatcher function to only allow paths to actual internal pages.
