We've replaced the "zephyr-docs" theme with a simpler read-the-docs
theme starting with the 1.13 release. This PR retrofits the theme
changes back onto this 1.9 release and ignores attempts to use the
zephyr-docs theme controlled by the make DOC_TAGS option.

Also needed to backport changes to the warning filtering system
implemented in later releases, fixes to how the config options were
generated (genrest.py).

When using the LE Create Connection Cancel command, the controller is
supposed to return a Command Complete first and then an LE Connection

this case emulate the behavior in the HCI layer instead.

Fix, add the missing code for the removal of any accumulated
soft latencies or negative drift ticks when scheduling next
interval expiry with added laziness.

Typically a first interval would accumulate soft latencies
and this has to be removed if the interval is rescheduled
with any added laziness (scheduled to the next soft real
time interval).

Example, scan windows block any new scheduling until the end
of the window, adding latencies to any soft real time ticker
expiry which should try to execute as early as possible after
the scan window.

Fixes: #6083

ticker timespace reservation can range up to 10.24 seconds,
needing 19-bits to represent in 32KHz clock units. Hence,
fix controller implementation to use u32_t to store ticks
slot values.

Without this fix, the controller is asserting in scan_adv
sample when using continuous scanning with 2 second interval
and window.

A previous patch which moved dispatching the health publish callback
to a later moment introduced a regression where the period divider
does not get updated when it should. In fact, having the divider as
part of the Health Server context is redundant, since the same
information is already stored generically in the model publication
context. Switching to using the model publication context makes things
simpler and ensures that the value is always up-to-date.
