Reviewed by Dewei Zhu and Alexey Proskuryakov.

Enhance http/tests/resources/network-simulator.py to support an initial response delay,
and variable chunk size, and chunk delay. This makes it possible to use to simulate
a slow-loading resource (potentially replacing the various "slow.pl" scripts we already have).

Add PDF as a valid resource type, and fix some typos.

A new test exercises the added functionality.

* LayoutTests/http/tests/harness/resources/chunked.txt: Added.
* LayoutTests/http/tests/harness/slow-loading-html-iframe.html: Added.
* LayoutTests/http/tests/resources/network-simulator.py:
(content_type):
