This commit removes EmbeddedNamespaceValue and ConstEmbeddedNamespaceValue and reduces NamespaceValue down to a simple struct without inheritance or member functions. The code from these clases is inlined into the Namespace class. The class hierarchy determining whether a value is const is moved to an attribute of NamespaceValue. This is done in preparation for changes to the locking in the Namespace class. Currently, it relies on a recursive mutex. In the future, a shared mutex (read/write lock) should be used instead, which cannot allow recursive locking (without failing or risk deadlocking on lock upgrades). With this change, all operations requiring a lock for one operation are within one function, no recursive locking is not needed any more.
