Introduce `limits` middleware

Previously, the `Include` override used with the markdown plugin did not
provide the optional `args` parameter. This made it impossible to pass
arguments to a template used with that plugin.

1. Replace original `maxrequestbody` directive.
2. Add request header limit.

We now use the release program to assist in deploying Caddy (it is much
more integrated and automated): https://github.com/caddyserver/releaser

This older automation code can still be found in this gist:

httpserver: More path matching tests

Fixes #1645

This reverts commit e0ed7093.

* httpserver/all: Clean up and standardize request URL handling

The HTTP server now always creates a context value on the request which
is a copy of the request's URL struct. It should not be modified by
middlewares, but it is safe to get the value out of the request and make
changes to it locally-scoped. Thus, the value in the context always
stores the original request URL information as it was received. Any
rewrites that happen will be to the request's URL field directly.

The HTTP server no longer cleans /sanitizes the request URL. It made too
many strong assumptions and ended up making a lot of middleware more
complicated, including upstream proxying (and fastcgi). To alleviate
this complexity, we no longer change the request URL. Middlewares are
responsible to access the disk safely by using http.Dir or, if not
actually opening files, they can use httpserver.SafePath().

I'm hoping this will address issues with #1624, #1584, #1582, and others.
