16693	GL libraries not detected and none ending process.	Steve Moyes		"Hi,
Windows guest is unable to start with 3D acceleration enabled.  Having only 2D enabled results in Windows booting to a black screen.

First symptom: 
Starting virtualbox on the cli gets: 

{{{
$ virtualbox
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
}}}
Second symptom: 
Closing the GUI window does not always end the process (also experienced on a Windows host). CTRL-C has to be used.

Third symptom: 
Trying to start a VM with 3D acceleration gets the error:

{{{
Failed to open a session for the virtual machine win10.
The VM session was aborted.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: SessionMachine
Interface: ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}
}}}

Downgrading to version 5.1.18 resolves all of the above.
