[tarantool-patches] Re: [PATCH 0/3] introduce static allocator

[Vladislav Shpilevoy]

Pushed into the master, but with a change: tt_static_buf()
now uses static_aligned_alloc with alignment by 'intptr_t'.
So it can be used to allocate temporary arrays of any types.

Note, that I kept tt_static.h header, because small/static is
an allocator, not a string formatter. And I decided, that it
should not include string-related utils, stdio.h header etc.
