the library deal with the memory through the defined interface, usual
libc malloc/free methods are called usually. to allow it to work in the
environement when libc is not available, there is a trivial memory
manager implemented, so nothing needs to be changed in the library inself.

one of the most important point here is that the number of plugins is
not fixed, it will be grow with time changing evth icluding the disk
format and it will be much simplier to maintain it all in one place --
the reiser4 library.
