Description: Add autotool support to svrcore; have svrcore build shared libs
Fix Description: This is a pretty basic autotool-ization using libtool
to build the shared library. The vast majority of the work was done
by Toshio-san. However, there are a couple of extras worth noting:
1) Windows builds are different now. In order to build on Windows using
the MSVC compiler, you still have to use coreconf. I just could not get
configure/libtool to work correctly with the MSVC compiler. The old
makefile has been moved to src/Makefile.win, so you just have to
cd src ; make -f Makefile.win
I also updated the README and INSTALL.win to add this information.
2) I added some m4 files to find and figure out which nspr and nss to use
based on the environment and pkg-config.
