[DOC]
To avoid breaking how existing code works a new constant is introduced for
the RecursiveDirectoryIterator() that directs the code to follow symlinks.
This constant RecursiveDirectoryIterator::FOLLOW_SYMLINKS can be passed a
flag to the constructor to trigger symlink following.

# Class FilesystemIterator was introduced to have a better DirectoryIterator
# without having to change DirectoryIterator or RecursiveDirectoryIterator.
# On top of FilterIterator the new GlobIterator was introduced. This one allows
# to implement Countable(). But a glob stream flattens all structure, so it
# cannot be derived from RedursiveIterator. With the new structure all children
# of FilesystemIterator have nearly the same behavior. Just their capabilities
# are a bit different. Check out new inheritance tree on SplFileInfo:

- Remove all overloading hooks -> array_read/array_access must be rewritten
- Remove all basic iterators
- Remove all 'spl_' prefixing exposed to user level
- Add RecursiveIterator, RecursiveIteratorIterator
- Add DirectoryIterator, DirectoryTreeIterator
- Add some examples
