Version update to 6.0.12 (released September 03 2019 by Oracle)

This is a maintenance release. The following items were fixed and/or added:

- OCI export: handle empty disk image correctly
- API: fix potential crash when using the medium I/O functionality
- VBoxManage: fixed documentation of VBoxManage modifyvm uarttype documentation (bug #18759)
- Network: scrub inbound TCP URG pointer, working around incorrect OOB handling
- USB: Improved identification of power-saved devices on Windows hosts
- Audio: in the AC97 work around buggy guest drivers which reprogram the sampling rate, breaking audio in and/or audio out
- Linux host and guest: fix kernel module build for SLES 12 SP4 kernel
- 3D: fixed state saving and loading when the VBoxVGA graphics adapter is used with 3D enabled (bug #18802, 6.0.10 regression)
- Windows guests: fixed mouse cursor visibility updating
- Windows guests: fixed graphics corruption in Windows 10 search menu with VBoxSVGA adapter
- Windows guests: fixed dwm.exe crashes related to the WDDM driver for VBoxSVGA adapter when the VM has lots of RAM
- MacOS Guest Additions fail to start in 6.0.10 (bug #18793)
- Windows guests: fixed crashes when using shared folders (bug #18766)
- Linux guests: unprivileged users unable to create files inside shared folders (bug #18737)
- Linux guests: improve compatibility of vboxvideo.ko kernel module build logic (bug #18869)

- Merge host kmp and guest kmp into a single kmp. The existence of two different kernel module
packages is believed to be the reason that it is possible for a new kernel not to include
the necessary kernel modules (boo#1142955).

- Script vboxdrv.sh, which is called from the systemd service file, incorrectly called a routine
that does not exist when the kernel modules were not available. This call is changed to /sbin/vboxconfig
that will build the modules if the requisite packages are available. If that is not true, the
systemctl status vboxdrv will list the command needed to load the missing packages. This change
address part of boo#1142995.
