No effective change on POSIX, but on Win32 the defaults come from the

qemu-ga: ga_get_fd_handle(): abort if fd_counter overflows

Today we reset fd_counter if it wraps, but it's better to abort()
instead, as fd_counter should never reach INT64_MAX.

Hosts hold on to handles provided by guest-file-open for periods that can
span beyond the life of the qemu-ga process that issued them. Since these
