format: Set MBR partition type byte appropriately (RHBZ#1000428).

Windows won't see a filesystem unless the MBR partition type
byte is set correctly.

daemon: Allow labels to be set on DOS filesystems using 'dosfslabel'.

You can now use virt-format or virt-make-fs --label option to set a
label for a DOS filesystem:

$ ./run ./format/virt-format -a /tmp/test.img --filesystem=vfat --label=BOOT
$ ./run ./cat/virt-filesystems -a /tmp/test.img --all --long -h
Name       Type        VFS   Label  MBR  Size  Parent
/dev/sda1  filesystem  vfat  BOOT   -    1.0G  -
/dev/sda1  partition   -     -      0b   1.0G  /dev/sda
/dev/sda   device      -     -      -    1.0G  -

This also contains a small code refactoring.

javadoc: Install javadoc in $(datadir)/javadoc/libguestfs (without -java-$(version)).

Apparently this is the normal place for javadoc, and not
where we installed it before.

appliance: Use gzip-compressed cpio files if supermin-helper supports it.

supermin-helper >= 4.1.4 has new support for compressed cpio files
(not hostfiles).  Detect if this is supported, and use it.

RHEL 7: Emphasize libguestfs-winsupport package (RHBZ#627468).

This RHEL-only patch changes the error messages when the
inspection code cannot find an operating system inside the guest
image.  For a Windows guest this may happen because the user has not
installed the separate 'libguestfs-winsupport' package.  Therefore we
emphasize that the user may need to install this package.

Notes:

(1) In RHEL there are two pieces of inspection code, the old Perl code
(deprecated upstream) and the new C core inspection API.  Therefore
this patch has to touch two places with essentially the same change.

(2) This patch doesn't try to be clever and detect if it was a Windows
guest.  This should reduce the chance of failure.

Output from (Perl) virt-inspector now looks like this:

 $ virt-inspector disk.img
 No operating system could be detected inside this disk image.

 This may be because the file is not a disk image, or is not a virtual machine
 image, or because the OS type is not understood by virt-inspector.

 If you feel this is an error, please file a bug report including as much
 information about the disk image as possible.

 RHEL notice
 -------------
 libguestfs will return this error for Microsoft Windows guests if the
 separate 'libguestfs-winsupport' package is not installed. If the
 guest is running Microsoft Windows, please try again after installing
 'libguestfs-winsupport'.

Output from guestfish (ie. C core inspection API) now looks like this:

 $ guestfish -i disk.img
 guestfish: no operating system was found on this disk

 RHEL notice
 -------------
 libguestfs will return this error for Microsoft Windows guests if the
 separate 'libguestfs-winsupport' package is not installed. If the
 guest is running Microsoft Windows, please try again after installing
 'libguestfs-winsupport'.
RHEL 7: Remove libguestfs live (RHBZ#798980).

This isn't supported in RHEL 7.
RHEL 7: Exclude iptables from the appliance (RHBZ#858648).
RHEL 7: Ignore /etc/release if /etc/redhat-release exists (RHBZ#873219).

If the user has created /etc/release on a RHEL machine, don't
mis-detect the OS as NetBSD.
RHEL 7: Remove 9p APIs from RHEL (RHBZ#921710).
RHEL 7: Disable unsupported remote drive protocols (RHBZ#962113).

This disables support for unsupported remote drive protocols:

 * ftp
 * ftps
 * http
 * https
 * tftp
 * gluster
 * iscsi
 * rbd
 * sheepdog
 * ssh

Note 'nbd' is not disabled, and of course 'file' works.

We hope to gradually add some of these back over the lifetime of RHEL 7.
