malloc: put common memory functions to seperate file ...

These functions are needed independently of the specific
malloc implementation, so move them out.

Use nowadays function prototypes ...

Use a function prototype style as used in all other u-boot-v2 sources, too.
Also remove C++ support. We do not use C++ in this project.

Remove confusing macros that hide the real functions names ...

This feature is provided, to support more than u-boot-v2. But its more
confusing than helpful. Remove it and do it straight forward like all other
sources in this tree, too.

Use the native 'void' instead of 'Void_t' ...

We are in the *NIX world, so keep a 'void' as is.

Move private settings and configuration into the C source ...

Include the board config first to be able to configure the memory management
in the documented way. If not used, the defaults are used.
On the other hand, there is no need to pollute the other source files with
these local management settings. So, move them from the header into the
C source file.
