2016-10-28clean-up: removed duplicate #includesAnand J
Some files contain multiple #includes of the same header file. Removed most of those unnecessary duplicate entries using scripts/clean-includes. Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Anand J <anand.indukala@gmail.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2016-10-28scripts/clean-includes: added duplicate #include checkAnand J
Enhance the clean-includes script to optionally check for duplicate #include entries. Script might output false positive entries as well. Such entries should not be removed. So if it finds any duplicate entries script will terminate with an exit status 1. Then each and every file should be checked manually and corrected if necessary. In order to enable the check use --check-dup-head option with scripts/clean-includes.

2016-10-28s390: avoid always-true comparison in s390_pci_generate_fid()Peter Maydell
Coverity points out that the comparison "fid <= ZPCI_MAX_FID" in s390_pci_generate_fid() is always true (because fid is 32 bits and ZPCI_MAX_FID is 0xffffffff). This isn't a bug because the real loop termination condition is expressed later via an "if (...) break;" inside the loop, but it is a bit odd. Rephrase the loop to avoid the unnecessary duplicate-but-never-true conditional.

2016-10-27fdc: Move qdev properties to FloppyDriveKevin Wolf
This makes the FloppyDrive qdev object actually useful: Now that it has all properties that don't belong to the controller, you can actually use '-device floppy' and get a working result. Command line semantics is consistent with CD-ROM drives: By default you get a single empty floppy drive. You can override it with -drive and using the same index, but if you use -drive to add a floppy to a different index, you get both of them. However, as soon as you use any '-device floppy', even to a different slot, the default drive is disabled. Using '-device floppy' without specifying the unit will choose the first free slot on the controller.

2016-10-27block/nbd: Add nbd_has_filename_options_conflict()Max Reitz
Right now, we have four possible options that conflict with specifying an NBD filename, and a future patch will add another one ("address"). This future option is a nested QDict that is flattened at this point, requiring us to test each option whether its key has an "address." prefix. Therefore, we will then need to iterate through all options (including the "export" option which was not covered so far). Adding this iteration logic now will simplify adding the new option later. A nice side effect is that the user will not receive a long list of five options which are not supposed to be specified with a filename, but we can actually print the problematic option.

Commit 076003f5 added configuration for NFS with IMGOPTSSYNTAX enabled, but it didn't use the right variable name: $TEST_DIR_OPTS doesn't exist. This fixes the mistake. However, this doesn't make anything work that was broken before: The only way to get IMGOPTSSYNTAX is with -luks, but the combination of -luks and -nfs doesn't get qemu-img create commands right (because qemu-img create doesn't support --image-opts yet), so even after this fix some more work would be required to make the tests pass.
