buflib_allocatable() is what buflib_available() was before (it was in fact
simply renamed). It returns the largest contiguous block of memory. This
can be allocated and will definitely succeed, although larger allocations
may also succeed if the buffer can be compacted and shrinked.
buflib_available() now counts all free bytes, contiguous or not. This
better matches the description and how the caller use it.

purposes.
This allocation can be freed in the buflib debug menu (select it to free).
Doing a another allocation, e.g. by selecting another item in this debug menu
will cause compaction (all allocs move).

The buflib memory allocator is handle based and can free and
compact, move or resize memory on demand. This allows to effeciently
allocate memory dynamically without an MMU, by avoiding fragmentation
through memory compaction.
This patch adds the buflib library to the core, along with
convinience wrappers to omit the context parameter. Compaction is
not yet enabled, but will be in a later patch. Therefore, this acts as a
replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug
menu.
See buflib.h for some API documentation.
