As the current File Servers don't yet support file sizes > 2^31-1 (except for ext2 with some work), the VFS-FS protocol negotioting field now has a field that FSes can use to indicate they do support 64-bit off_t. When they do, VFS will accept 64-bit results. Otherwise VFS will zero out the upper 32 bits. The previous commit contained a hack to support truncate for dynamically linked binaries. This commit removes it as it's no longer necessary. Change-Id: I07189d410094b193cb7bbd3f2507537bb1e7f96c
