Add libtool support.
libzebra and libospfapiclient are now built shared, and linked shared
with the daemons. This reduces the memory needed when running
multiple daemons; each daemon is at least 150k smaller. Static
libraries are still built, and libtool should use them on platforms
which don't have shared libaries. As with autoconf, the user of a
distribution does not need libtool; one just needs that to build from
CVS.
libospf.a is still a non-shared library, and still installed, not
because that makese sense, but because I don't understand why it is
the way it is now.
Note that the tree was tagged 'libtool-before' just before this commit.
