Use print functions instead of python statements to be compatible with python 3.X and 2.7 as well.
Archlinux has been using python3 and that is what causes issues while packaging QtWebKit along with Qt5.

JSObject::getOwnNonIndexPropertyNames calculates numCacheableSlots incorrectly (2/2)

If the object doesn't have any properties but the prototype does, we'll assume those prototype properties are
accessible in the base object's backing store, which is bad.

JSObject::getOwnNonIndexPropertyNames calculates numCacheableSlots incorrectly

Reviewed by Geoffrey Garen.

Due to the way that numCacheableSlots is currently calculated, checking an object's prototype for enumerable
properties causes us not to cache any properties at all. We should only cache properties on the object itself
since we currently don't take advantage of any sort of name caching for properties in the prototype chain.
This fix undoes a ~2% SunSpider regression caused by http://trac.webkit.org/changeset/147570.

get_by_pname can become confused when iterating over objects with static properties

https://bugs.webkit.org/show_bug.cgi?id=113831

Reviewed by Geoffrey Garen.

get_by_pname doesn't take static properties into account when using a JSPropertyNameIterator to directly
access an object's backing store. One way to fix this is to not cache any properties when iterating over
objects with static properties. This patch fixes the bug that was originally reported on swisscom.ch.

[Qt] Use GNU ar's thin archive format for intermediate static libs

2013-04-19T15:13:21+00:00

https://bugs.webkit.org/show_bug.cgi?id=109052
http://trac.webkit.org/changeset/142088

Reviewed by Jocelyn Turcotte.

With debug builds we exceed the 4GiB limit of GNU ar when creating the WebCore
intermediate static library which results in build failure even with a x86_64
toolchain (http://sourceware.org/bugzilla/show_bug.cgi?id=14625).

When using a GNU toolchain we can use the thin archive format for these static
libraries which also has the benefit of not copying the object files, thus
drastically reducing disk usage and overall compile time.

Currently qmake does not support GNU ar's thin archive format so for
now we need to do the magic in the build system as a stopgap solution.

Adjust project files that used activeBuildConfig()
to use targetSubDir().
