Library ABI tracking with abigail
Provide two make targets: checkabi and storeabi.
storeabi uses libabigail to generate a reference copy of the ABI for the
public libraries.
checkabi compares such a reference to the compiled version, failing if
they are not compatible. No ABI is generated for libzpool.so, it is
only used by ztest and zdb and not external consumers.
