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).

# remove_x_headers
```
message:remove_x_headers([NAMES])
```
When called with no parameters, removes all headers with an `"X-"` prefix from
the message.
When called with a list of header names, only those headers, if present in the
message, will be removed from the message.
For example, with a message content of:
```
X-Campaign-ID: 12345
X-Mailer: foobar
Subject: the subject
The body
```
calling:
```lua
message:remove_x_headers()
```
will result in the body changing to:
```
Subject: the subject
The body
```
but calling:
```lua
message:remove_x_headers { 'x-campaign-id' }
```
will result in the body changing to:
```
X-Mailer: foobar
Subject: the subject
The body
```
