Adds support for the DHCP portion of the WPAD (proxy auto-discovery) protocol.

This is Windows-only for now, and is disabled by default. Start Chrome with the flag --enable-dhcp-wpad to enable the feature. See discussion in comment on DhcpProxyScriptFetcherFactory for why this needs to be done in a per-platform way rather than cross-platform. The code is factored so that adding other platform implementations will be straight forward. Most of the implementation is stand-alone and extends the ScriptProxyFetcher class hierarchy (and makes its interface slightly more generic). The integration point into existing code is in InitProxyResolver, which previously handled fallback from DNS auto-detect to custom PAC URL and now does fallback from DHCP to DNS to custom PAC URL. BUG=18575 TEST=net_unittests has good coverage for the new and changed code, but manual tests on a network with a PAC URL configured in DHCP are also needed. Original commit r85646. Reverted (test failures on some release bots) r85648. Will reland with fix.
