Define monotonic_buffer_resource members out-of-line
Move the allocation logic into libstdc++.so so that it can be changed
without worrying about inlined code in existing binaries.
Leave do_allocate inline so that calls to it can be devirtualized, and
only the slow path needs to call into the library.
* config/abi/pre/gnu.ver: Export monotonic_buffer_resource members.
* include/std/memory_resource (monotonic_buffer_resource::release):
Call _M_release_buffers to free buffers.
(monotonic_buffer_resource::do_allocate): Call _M_new_buffer to
allocate a new buffer from upstream.
(monotonic_buffer_resource::_M_new_buffer): Declare.
(monotonic_buffer_resource::_M_release_buffers): Declare.
(monotonic_buffer_resource::_Chunk): Replace definition with
declaration as opaque type.
* src/c++17/memory_resource.cc (monotonic_buffer_resource::_Chunk):
Define.
(monotonic_buffer_resource::_M_new_buffer): Define.
(monotonic_buffer_resource::_M_release_buffers): Define.
