7ec08af6d9 usb: session renewal & new client API
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

913196e2dc record_play_mixer: smoothen time-window allocation
This patch modifies the mixer's time window allocation by modelling the
drift of the period length over time. This yields a much better

07669ac991 os: record-and-play session interfaces and mixer
- New session interfaces:
  - os/include/play_session   (for audio playing   / mic-input driver)
  - os/include/record_session (for audio recording / audio-output driver)
- Mixer at os/src/record_play_mixer providing both play and record services
- Simple waveform player at os/src/app/waveform_player
- Simple audio-signal capturing component at os/src/app/record_rom
- Simple oscilloscpe at gems/src/app/rom_osci (using record_rom)
- Simple test-audio_play for playing raw stereo f32 data

The _gems/run/waveform_player.run_ script illustrates the use of the new
components and interfaces.

1336b0a751 mmio: upper-bounds checks
The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).

That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.

Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.

The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.

The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.

Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.

c23491ef3c nic_uplink: connect a Nic to an Uplink session
* Adds a new component server/nic_uplink that forwards packets unmodified
  between one Uplink session at one side and potentially multiple Nic sessions
  at the other side.
* Adds a new run script nic_uplink.run that does a basic test with multiple
  Nic clients on this component and adds it to the autopilot list.
* Adds a new depot recipe src/nic_uplink for this component.
* Adds a new depot recipe pkg/pc_nic for deploying the pc_nic_driver together
  with a nic_uplink server. This allows for raw access to the network connected
  to the Nic of the system in contrast to the commonly used routed and NAT'd
  access via NIC router. That said, it enables the use of network protocols
  not yet supported by the NIC router at the cost of less protection.

f7b910b298 part_block: split reporting from parsing
Previously the 'partitions' report was implicitly generated after
parsing the partition-table by accessing the referenced reporter
object.

Now the report is explicitly created by calling the 'generate_report'
member function. At this point we no longer have access to all
required information so the 'Partition' class was extended to
accommodate for the data needed by MBR as well as GPT reports.

c5b9cabd89 vmm: enable effective C++ error switch
Several explicit casts could not be avoided yet, due to the missing

bdf47785b8 vfs: remove 'file_size' from read/write interfaces
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.

Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.

This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.

  * Introduces != operator to the public Port class in the net library.
