A user can now simply use the new option "GIT_OPT_SET_ALLOCATOR" with `git_libgit2_opts`, passing in an already initialized allocator structure as vararg.

alloc: make memory allocators use function pointers 2018-06-07T10:57:39+00:00 Patrick Steinhardt ps@pks.im 2018-03-20T14:23:49+00:00 9865cd1696ac4a3f47991a9a1d79b17cef5edc89 Currently, our memory allocators are being redirected to the correct implementation at compile time by simply using macros. In order to make them swappable at runtime, this commit reshuffles that by instead making use of a global "git_allocator" structure, whose pointers are set up to reference the allocator functions. Like this, it becomes easy to swap out allocators by simply setting these function pointers. In order to initialize a "git_allocator", our provided allocators "stdalloc" and "crtdbg" both provide an init function. This is being called to initialize a passed in allocator struct and set up its members correctly. No support is yet included to enable users of libgit2 to switch out the memory allocator at a global level. 
Currently, our memory allocators are being redirected to the correct

In order to initialize a "git_allocator", our provided allocators
"stdalloc" and "crtdbg" both provide an init function. This is being
called to initialize a passed in allocator struct and set up its members
correctly.

No support is yet included to enable users of libgit2 to switch out the
memory allocator at a global level.
