Only a few cases are allowed:
1) The expression is empty for "for" loop, E.g.
for (i = 0; ; i++)
2) An empty statement
while (write(statuswrite, &status, 1) == -1 &&
errno == EINTR)
; /* empty */
3) ";" is inside double-quote, I.e, as part of const string. E.g.
vshPrint(ctl, "a ; b ; cd;\n");
The "for" loop in src/rpc/virnettlscontext.c is the special case,
1) applies for it, so change it together in this patch.
