A system shell that works in a small window stops working when maximized
on a 4k screen, because the terminal component runs out of RAM.
With the adjusted RAM quotas the system shell works on 4k displays.

for other VMMs beside Virtualbox, e.g. Seoul or potentially arm/vmm. The
webcam model depends on libyuv, which uses stdcxx + full libc, which is not
desired or required for all VMM implementations.

Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.
The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.
The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.
This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.
The adaptations necessary target the following areas:
* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
with the new policy rules of the USB host controller driver

The package depends on two resources.
- A Nic session should be routed to the nic_router "http" domain make
the HTTP server available from the outside on forwarded port 80.
- A File_system session labeled "webroot" can be routed to any server
by relabeling the session, e.g., to "report" or "config" in parent.
Sculpt deploy exmaple exporting report_fs via HTTP.
<start name="lighttpd" pkg="lighttpd">
<route>
<service name="Nic">
<child name="nic_router" label="http"/>
</service>
<service name="File_system" label="webroot">
<parent label="report"/>
</service>
</route>

Hitting a BOSD in a Windows guest in Virtualbox 6 leads to calling
`DBGFR3ReportBugCheck`, which leads to the following error since it is
unimplemented in our port:
```
Error: DBGFR3ReportBugCheck: DBGFR3ReportBugCheck called, not implemented, eip=0x1a5c4e4
```
Including the actual method from Virtualbox 6 enables logging
diagnostics for the Windows Blue Screen of Death (BSOD).
To see Blue Screen logging output, enable "dbgf" and "gim" logging
via the `VBOX_LOG` following environment variable in the vbox6 runtime
config.
When manually triggering a BSOD in the Windows guest, this should
produce the following logging diagnostics:
```
GIM: HyperV: Guest indicates a fatal condition! P0=0xe2 P1=0x0 P2=0x0 P3=0x0 P4=0x0
GIMHv: BugCheck e2 {0, 0, 0, 0}
