Message:

Support for preconnect Link headers
​https://bugs.webkit.org/show_bug.cgi?id=181657

Reviewed by Darin Adler.

Source/WebCore:

Move the preconnect functionality into its own function, and
also call this function when Link headers are processed.

Test: http/tests/preconnect/link-header-rel-preconnect-http.php

• loader/LinkLoader.cpp:

(WebCore::LinkLoader::loadLinksFromHeader): Call preconnectIfNeeded.
(WebCore::LinkLoader::preconnectIfNeeded): Preconnect to a host functionality moved here.
(WebCore::LinkLoader::loadLink): Call preconnectIfNeeded.

• loader/LinkLoader.h:

LayoutTests:

Add test to see Link preconnect headers trigger a connection.

• http/tests/preconnect/link-header-rel-preconnect-http-expected.txt: Added.
• http/tests/preconnect/link-header-rel-preconnect-http.html: Added.
• http/tests/preconnect/resources/header-preconnect.php: Added.
• platform/win/TestExpectations: Skipped the preconnect test directory, rather than the individual files in it.
