Hi all,

In the fifth version I corrected remarks from Pedro Falcato and Marvin Häuser.
I moved symlink procedures into independent C file, corrected code style like
debug messages macros and etc.

This patchset adds symbolic links support with simple recursion protection based
on symbolic link nest level limitation, also I included patch which adds BASE_CR
to extract EXT4_FILE private structure to prevent possible code corruption caused
by structure changes and rearrangements in future.
