The number of buffres influences e.g. the maximum SDU size, which in
turn influences call stack consumption. Use lower values where a high
number of buffers isn't necessary, and use the default (6) where it's
sufficient.

Trying to always include mesh support resulted in the app not fitting
on some boards (e.g. nrf51_pca10028). Put the mesh-specific
configuration in a separate configuration file instead.
