MEDIUM: http_act: Rename uri-normalizers

This patch renames all existing uri-normalizers into a more consistent naming
scheme:

1. The part of the URI that is being touched.
2. The modification being performed as an explicit verb.

Performs normalization of the request's URI. The following normalizers are
available:
- dotdot: Normalizes "/../" segments within the "path" component. This merges
segments that attempt to access the parent directory with their preceding
segment. Empty segments do not receive special treatment. Use the
"merge-slashes" normalizer first if this is undesired.
- path-strip-dotdot: Normalizes "/../" segments within the "path" component.
This merges segments that attempt to access the parent directory with

- merge-slashes: Merges adjacent slashes within the "path" component into a
single slash.
- path-merge-slashes: Merges adjacent slashes within the "path" component
into a single slash.
Example:
- // -> /
- /foo//bar -> /foo/bar
- percent-upper: Uppercases letters within percent-encoded sequences

Example:
- /%zz -> HTTP 400
- sort-query: Sorts the query string parameters by parameter name.
- query-sort-by-name: Sorts the query string parameters by parameter name.
Parameters are assumed to be delimited by '&'. Shorter names sort before
longer names and identical parameter names maintain their relative order.
