Why? If a function is static, we can be sure it's not called from
outside of the file. Moreover, I'd direct your attention to recent
commit of f557b3351e0b6d for instance. In fact whole qemu driver serves
as a great example: it's "static int qemuDomain*()" not "static vir
virQEMUDomain*()".

In fact, I'd suggest the opposite rule - use "vir" prefix only if
function is shared between modules. For instance  virFileCopyACLs should
have the vir prefix because it's exported. virFileRewriteStrHelper
should not have the prefix because it's static.
The advantage of this approach is that one can immediately tell just
from the name if the function is exported or not.
