Wez Furlong 42bf5c5e61 docs: adjust reference to improve search terms
We've been hoping that mkdocs-material will ship the much anticipated
search enhancements for some time, but it's time to recognize that
we need to do something to improve the search results with how
things work right now.

This is a big commit that changes the titles of the various pages
from the code-annotated synopsis to just the name of the function.

This makes it much easier now to match things like `kumo.reject`
directly, but `reject` remains awkward to find.

I think this is the best that we can do at this time.

A few functions have been annotated with the `status: deprecated` to
show as deprecated in the toc/nav (shows with a little trash can next
to the name).

# tsa_load_shaping_data
```lua
kumo.on('tsa_load_shaping_data', function() end)
```
{{since('2023.08.22-4d895015')}}
Called by the `tsa-daemon` whenever it is going to evaluate a newly received log record.
The event must return a `Shaping` object, as can be obtained via
[kumo.shaping.load](../kumo.shaping/load.md).
It is recommended that you use the same list of filenames that you would use
with the shaping helper so that the two services have a consensus on the
shaping configuration.
`tsa-daemon` is only really concerned with automation rules defined by the
shaping configuration.
```lua
local tsa = require 'tsa'
local kumo = require 'kumo'
kumo.on('tsa_init', function()
tsa.start_http_listener {
listen = '0.0.0.0:8008',
trusted_hosts = { '127.0.0.1', '::1' },
}
end)
local cached_load_shaping_data = kumo.memoize(kumo.shaping.load, {
name = 'tsa_load_shaping_data',
ttl = '5 minutes',
capacity = 4,
})
kumo.on('tsa_load_shaping_data', function()
local shaping = cached_load_shaping_data {
-- This is the default file used by the shaping helper
-- in KumoMTA, which references the community shaping rules
'/opt/kumomta/share/policy-extras/shaping.toml',
-- and maybe you have your own rules
'/opt/kumomta/policy/shaping.toml',
}
return shaping
end)
```
