- Replace old non-PIC 62-bit linux libs (GMP 4.1.4 built in 2005)
        with PIC libs built with GMP 5.0.2. License is LGPLv3.
        Built by sponge with GCC 4.4.4, downloaded from
        http://sponge.i2p/files/jbigi/gmp-5.0.2/
        For 64-bit processors, both performance testing and
        the GMP changelog led us to use 5.0.2 for both the 32- and 64-bit versions,
        even though the files are twice as big.
        See http://zzz.i2p/topics/306 for discussion and test results.
        libjbigi-linux-athlon64.so was a 64 bit file; by the new naming standard
        supported by NativeBigInteger, it is now a 32-bit file and the
        64-bit one is libjbigi-linux-athlon64_64.so.
        All new 64-bit libs will have _64 appended.

        NBI now tries athlon as a fallback for all 64-bit processors.

             with PIC libs built with GMP 4.3.2. License is LGPLv3.
             Built by sponge with GCC 4.4.4, downloaded from
             http://sponge.i2p/files/jbigi/gmp-4.3.2/
             The 4.3.2 files are half the size of those built with GMP 5.0.2, and there was
             little or no performance difference between the two versions for 32 bit processors.

Don't prefer IPv4 but add the option commented out to wrapper.config. Make the option configurable in runplain.sh

In some distributions (such as Debian, for example) net.ipv6.bindv6only=1 is
set by default. In some configurations, networking in java applications will be
broken. Someone recently came into #i2p experiencing this very problem.

This change closes #464.

Compiled using
gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2nexenta7) on Nexenta 3.0.1

Braces were put around variable names so that router will run in kFreeBSD.
runplain.sh should now be shell agnostic (it runs in dash. it even runs in
*posh*, a ridiculously picky shell).

to k62 versions; add mapping in NativeBigInteger.
