SetFilePointer returns INVALID_SET_FILE_POINTER when it fails. In addition, GetLastError must be checked. The first call of SetFilePointer did not use INVALID_SET_FILE_POINTER, the second call used wrong error handling.

Some guests will use the standard MII status register to verify link state. They will not notice link changes unless this register is updated. Verified with Linux 3.0 and Windows XP guests. Without this patch, ethtool will report speed and duplex as unknown when the link is down, but still report the link as up. This is because the Linux e1000 driver checks the mac_reg[STATUS] register link state before it checks speed and duplex, but uses the phy_reg[PHY_STATUS] register for the actual link state check. Fix by updating both registers on link state changes.

This patch tries to cull any uneeded library dependencies from the guest agent to improve portability across various distros. We do so by being as explicit as possible about in-tree dependencies rather than relying on existing *-obj-y targets, and by manually setting LIBS for the qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by configure.
