Synchronous body reader now exposes a peek() function to get the first few bytes
from the response body. This will be no less than 100 bytes (assuming the body
is that big), but could be more. Streaming API, via res.next() continues to work
as-is even if peek() is called.
Introduce Mime.sniff() that detects a few common types - the ones that we care
about right now - from the body content.
The HTTP response values _are_ mutable, but because we're using std.http.Header
the type is a `[]const u8`. This introduce a custom `Header` type where the
value is `[]u8`.
The goal is largely to allow more efficient value-comparison, by allowing
calling code to lower-case in-place. I specifically have the Mime parser in
mind:

Combine uri + rawuri into single struct.
Try to improve ownership around URIs and URI-like things.
- cookie & request can take *const std.Uri
(TODO: make them aware of the new URL struct?)
- Location (web api) should own its URL (web api URL)
- Window should own its Location
Most of these changes result in (a) a cleaner Page and (b) not having to carry
around 2 nullable objects (URI and rawuri).
When we only have 1 or 2 bytes missing from a chunk (i.e. the tailing \n or
\r\n), don't emit an empty chunk if we have more data available to process.
When set, this disables the host verification of all HTTP requests. Available
for both the fetch and serve mode.
Also introduced an App.Config, for future command line options which need to
be passed more deeply into the code.
