[Tarantool-patches] [PATCH v2 0/5] Choose allocator for memtx

[mechanik20051988]

Branch: https://github.com/tarantool/tarantool/tree/mechanik20051988/gh-5419-choose-allocator-for-memtx-cpp-14
        (Do not pay attention to the number 14 in the branch header)
Issue: https://github.com/tarantool/tarantool/issues/5419
Pull request: https://github.com/tarantool/tarantool/pull/5670

Changes in v2:
	Change checkpoint_interval option in test to manually calling box.snapshot()
	Separate third commit on two part (now commit 3 ad 5)
	Write detailed commit messages

About patches:
	1. First patch add performance test for memtx allocator. You can copy perf folder 
	   to master branch and compare performance.
	2. Second patch convert some *.c files to *.cc files. 
	   This is the preparation for the patch with allocator choise
	3. Third patch template tuple allocation, based on allocator type
	4. Fourth patch add system allocator based on malloc and free
	5. implement api for memory allocator selection

	In accordance with the comments on previous patches i use box.snapshot() manually in test
	instead of using checkpoint_interval option. Also i separate third commit on two parts (3 and 5),
	and write detailed commit messages that answer the questions in the comments on previous patches  

mechanik20051988 (5):
  test: add performance test for memtx allocator.
  memtx: changed some memtx files from .c to .cc
  memtx: implement template tuple allocation
  Implement system allocator, based on malloc
  memtx: implement api for memory allocator selection
