Use pool allocator in QueryHeap

[SiarheiFedartsou]

I spent some hours in profiler and noticed that we waste a lot of time for allocations in QueryHeap:

• in std::unordered_map in UnorderedMapStorage - it is quite obvious it has to reallocate pairs quite often, just because of the way how it is implemented
• in boost::heap::d_ary_heap - initially I thought it is very weird, because I saw that it is based on std::vector under the hood(i.e. should just re-use already allocated memory), but then after some debugging I realised that there is also std::list, which as I understood is used in the case if we need heap to be mutable (in other words if we want to be able to decrease priorities, what we obviously need).

After some experiments I ended up with custom pool allocator which uses thread local free lists to re-use already allocated memory. Idea is primitive:

• we allocate chunk of memory using malloc and then when we need to allocate object(s) we allocate block of memory from this chunk which is of least possible 2^N size
• when memory is deallocated we put it to one of free lists, index of free list is determined by N (if size is 2^N)
• next time when we need to allocate something we look into corresponding free list first and allocate new block only if it is needed

What alternatives I considered, but rejected

• boost::fast_pool_allocator - it worked well on benchmarks(~ the same as current solution), but it has huge problem which made me to reject it completely... It uses singleton pool under the hood (similar to this implementation) and it has no thread local implementation, i.e. either we use single pool for all threads and protect it by mutex (it eats all the performance improvements from using memory pool) or don't use threads at all (what is impossible for OSRM)
• https://en.cppreference.com/w/cpp/memory/unsynchronized_pool_resource - initially looked intresting, but unfortunately boost::heap::d_ary_heap seems to not support it

Result highlights

Measured on my Raspberry Pi: map matching CH (default radius) ops/sec: +22% map matching MLD (default radius) ops/sec: +35%(!) table CH (25 coordinates) ops/sec: +8% table MLD (25 coordinates) ops/sec: +8% route CH (overview=full, steps=true) ops/sec: +1% route MLD (overview=full, steps=true) ops/sec: +10% osrm-contract run time: -20% osrm-customize run time: -23%

Worth saying that that there is some improvements almost in all benchmarks...
