buffers: support per-numa-domain buffer size
Currently, buffers-per-numa is used for all NUMA domains, and there's
no way to allocate different amounts for each domain.
Therefore, this adds a per-NUMA-domain buffer config section, which
currently has a single option to set the number of buffers.
If it's not specified or set to zero, the code falls back to
buffers-per-numa as before.
Type: improvement
