The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
Those values are used in various call (including zpp) where
a size_t is expected.
This fix 82 failed test on ppc64
(bigendian is perfect to detect stack issue)
directories).
[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:
