[PATCH 0/3] Make heap API more friendly

[Vladislav Shpilevoy]

This patchset fixes some flaws in the salad heap API. First of all, fixed the
most irritating thing - a necessity to constantly call constainer_of in the code
because of heap's inability to cope with user-defined structures.

Secondly, fixed a hole in encapsulation of heap_node structure, which was
expluatated by vinyl.

Thirdly, fixed heap reserve behaviour, which was not really reserve(), but
rather twice().
