openbor Tools

Added a tracerealloc() function to tracelib that wraps around realloc() in the standard C library.

Bazaar revision numbers can now be used as the build number when the 'svn-revno' property is not available.

Fixed build numbers for bzr-svn. The Bazaar version control system should now work as a complete alternative to SVN through the bzr-svn plugin.

Fixed version.sh in Windows when the SVN executable is in the PATH, not in tools/bin.

Fixed a 'long is 32 bits' assumption in the SDL menu's font renderer. It appears to be the only such assumption in the SDL backend.

x86_64 Linux building works without cross-compiling now. Thanks for AL13N for confirming that these changes fix the build.

OpenBOR now compiles under 64-bit (x86_64) Linux. I'm not sure yet whether it's buggy or ready for general use.

Removed some unneccessary lines in build.sh that I left in accidentally in 2926.

Linux ports can now be compiled for multiple architectures. Currently, x86 and x86_64 are supported:
./build.sh 4 x86
./build.sh 4 amd64

Calling "./build.sh 4" with no other arguments implies x86.

Another compile fix. This time I actually made sure the whole thing compiles before committing.
