[Qt] Add API for managing origin quotas in appcache

[Robert Hogan]

Add the following API for managing cases where the application cache quota is exceeded in total or per origin.

+    \fn void QWebPage::applicationCacheQuotaExceeded(qint64 spaceNeeded);
+    \since 4.5
+
+    This signal is emitted whenever a web site is asking to store data
+    to the application cache and the maximum size allocated to the cache is exceeded.
+    A slot connected to this signal can decide whether to increase the maximum size
+    of the application cache with QWebSettings::setOfflineWebApplicationCacheQuota(qint64 maximumSize)
+    to prevent future failures.
+
+    \sa QWebDatabase
+*/
+
+/*!
+    \fn void QWebPage::applicationCacheQuotaPerOriginExceeded(QWebSecurityOrigin* origin);
+    \since 4.8
+
+    This signal is emitted whenever the web site from \a origin is asking to store data
+    to the application cache and the quota allocated to that \a origin is exceeded.
+    A slot connected to this signal can decide whether to increase the quota allocated
+    to the application cache for the \a origin with
+    QWebSecurityOrigin::setOfflineWebApplicationCacheQuota(qint64 quota).
+
+    \sa QWebDatabase
+*/
+

+    Sets the quota for the application cache in the security origin to \a quota bytes.
+
+    If the quota is set to a value less than the current usage, the quota will remain
+    and no data will be purged to meet the new quota. However, no new data can be added
+    to application caches with this origin.
+*/
+void QWebSecurityOrigin::setOfflineWebApplicationCacheQuota(qint64 quota)

+    \since 4.8
+
+    Sets the default maximum size of the cache for an offline web application
+    used by any given QWebSecurityOrigin to \a maximumSize.
+*/
+void QWebSettings::setOfflineWebApplicationCacheQuotaPerOrigin(qint64 maximumSize)

+
+/*!
+    \since 4.8
+
+    Returns the default maximum size of the cache for an offline web application
+    used by any given QWebSecurityOrigin.
