Bug 126480 – Move process suppression of WebProcess to WebPage (from UIProcess)

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Gavin Barraclough]

Let each page take a UserActivity rather than having to coalesce this state, and take different activity tokens for normal visibility and suppression disabled, so we can see why the process is not suppressed.

This could use a more descriptive name.

Additionally it broke the Apple Windows build too:

     1>WebCore.lib(PageThrottler.obj) : error LNK2019: unresolved external symbol "public: __thiscall WebCore::UserActivity::UserActivity(char const *)" (??0UserActivity@WebCore@@QAE@PBD@Z) referenced in function "public: __thiscall WebCore::PageThrottler::PageThrottler(class WebCore::Page &)" (??0PageThrottler@WebCore@@QAE@AAVPage@1@@Z)

(Unfortunately you didn't have chance to catch it early, because Win EWS bots are out of order long time ago.)

It broke the non Mac builds, because only Apple 
supports this kind of forwarding headers.

Fix landed in http://trac.webkit.org/changeset/161320 nad http://trac.webkit.org/changeset/161321 .

Looks like Windows build is still broken.

[Simon Fraser (smfr)]

This broke windows:

This change broke the Windows build.  See Bug 126526 for the fix.
