Subpixel layout: Legacy Element.offset* client* return values are invalid in certain cases.
https://bugs.webkit.org/show_bug.cgi?id=133272

Reviewed by Simon Fraser.

Element.offset* client* functions applied various rounding strategies on the return values before r168868.
(for example, offsetLeft/Top either floored through implicit integer arithmetics or rounded explicitly depending
whether the zoom scale was 1. see http://trac.webkit.org/changeset/168868/trunk/Source/WebCore/dom/Element.cpp for details)
This patch mimics the legacy behavior by either rounding or flooring the return value.

Not testable (legacy switch is not exposed)

Exceptions raised when converting HTML/CSS are caught.
Files for which conversion failed are still copied to the target directory.
Each individual conversion failure is logged.

[CSS Grid Layout] Implementation of the "grid" shorthand.
https://bugs.webkit.org/show_bug.cgi?id=132122

Patch by Javier Fernandez <jfernandez@igalia.com> on 2014-05-26
Reviewed by Darin Adler.

Source/WebCore:
The grid property is a shorthand that sets all of the explicit
grid properties (grid-template-rows, grid-template-columns, and
grid-template-areas) as well as all the implicit grid properties
(grid-auto-rows, grid-auto-columns, and grid-auto-flow) in a
single declaration

Notice that either explicit or implicit grid can be specified,
assigning the initial values to the omitted properties.

[GTK] WebProcess leaked when closing pages with network process enabled
https://bugs.webkit.org/show_bug.cgi?id=129684

Reviewed by Anders Carlsson.

Source/WebKit2:
The problem is that the web process is not notified when the UI
process closes the connection, because when close() is called on
the socket by the UI process, the socket is shared by another web
process launched later, preventing the connection from being
shut down. We need to set the CLOEXEC flag on the sockets file
descriptor to make sure they are not exposed to other processes.

* Platform/IPC/Connection.h: Add ConnectionOptions parameter to
createPlatformConnection() with a default value compatible with
existing callers.
* Platform/IPC/unix/ConnectionUnix.cpp:
(IPC::Connection::createPlatformConnection): Set the CLOEXEC flag
on the client and server socket file descriptors depending on the
options passed.
* UIProcess/Launcher/gtk/ProcessLauncherGtk.cpp:
(WebKit::ProcessLauncher::launchProcess): Use
IPC::Connection::createPlatformConnection() instead of
socketpair() directly, setting the CLOEXEC flag on the server
before spawning the new process and on the client right after
spawning the new process.

Tools:
Enable the test to check that web processes finish when the web
view is destroyed.
