3ff0efd627 vfs/pipe: add fifo feature to pipe plugin
The vfs pipe plugin can now be used as named pipe which anables data
transfer via file handles from one component to another. E.g. if one
would like to send data from component A to stdin of a libc component B,
one can do so by simply writing to that fifo file.

a6f0b05834 usb_host: properly handle ISOC read requests
* Update the 'packet_size' information with the actual length for
  each isoc frame to be able to handle short reads at the client side.

* Copy the whole transfer buffer because the host controller stores
  the data at the original offsets, i.e., the buffer is not densely
  packed.

Fixes #4018.

cf72d1aac3 os: introduce new "Uplink" session
Adds new Uplink session interface, the corresponding client side (Client,
Connection), and the corresponding API archives. An Uplink session is almost
the same as a NIC session with the difference that the roles of the end points
are swapped. An Uplink client is the one that provides a network interface
(for instance, a NIC driver) whereas an Uplink server is the one that uses
that network interface (for instance, a networking stack).

Therefore, in contrast to the NIC session, MAC address and link state come from
the Uplink client. The link state is reflected through the lifetime of an
Uplink session: The client requests the session only when the link state is
"UP" and closes it whenever the link state becomes "DOWN" again. The MAC
address is transmitted from the Uplink client to the Uplink server as an
argument of the session request.

a0fb944721 Propagate session diag flag to core
This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.

To control this feature, three possible policies can be expressed in a
routing target of init's configuration:

* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
  attribute

7fbb245710 os: add VirtIO device helper classes.
To simplify writing native VirtIO drivers for Genode add helper classes
representing VirtIO device and queue. The queue implementation should
be platform independant. The device abstraction however is closely tied
to the VirtIO transport being used (PCI/MMIO). Both PCI and MMIO
implementations expose the same public API so the actual driver logic
should be the same regardless of which transport is used.

Its also important to note that the PCI version of Virtio::Device
currently does not support MSI-X interrupts. Unfortunately my kowledge
about PCI bus is very limited and my main area of interest was to get
VirtIO drivers working on virt_qemu ARM/Aarch64 platform. As such all
the VirtIO drivers I plan to submit will work with PCI bus, but might
not use some extended capabilities.

2eb8c5e21a net: move ascii_to() into Net namespace
The combination of Net::Mac_address and
Genode::ascii_to(Net::Mac_address) required shaky quirks in several
places because GCC is not able to resolve the ascii_to overload if
base/xml_node.h was included to early. The current solution moves the
several ascii_to overloads "closer" to the Net types by putting them
into the Net namespace, where GCC reliably picks them up.

Hence, co-locating the ascii_to() utility with the overload type in the
same scope/namespace is good practice.

This patch removes the now obsolete <nic/xml_node.h> header file.

ef741ef80d Change pixel format to 32 bits per pixel
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.

The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.

2912096f6e vfs: distinguish NO_PERM from NO_ENTRY in unlink
This patch changes the 'Single_file_system' to return NO_PERM only if
the to-be-unlinked file corresponds to the single file. This way, a
<rom> co-mounted with a <ram> file-system does not stand in the way of
unlinking files from the <ram>. The concrete symptom occurred the
following scenario:

  <vfs>
    <dir name="home">
      <ram/>
      <rom name="..."/>
    </dir>
  </vfs>

The following sequence of commands wrongly resulted in "Operation not
permitted":

 $ mkdir -p /home/a/b/c
 $ rm -f /home/a/b/c/d

In this case, rm should not fail (unlink should return ENOENT)

52e582132f os/vfs.h: handle corner case in join function
When specifying "/" or "" as rel_path to the 'Directory' constructor,
the constructed directory should refer to the same directory. The
implementation of the join utility did not consider this corner case. It
occurred during the attempt to use fs_query with "/" given as path.

if the entry is a directory.

f82e7df0ba os/buffered_xml.h: support for generating XML
This patch extends the 'Buffered_xml' utility with a new constructor
that fills the buffer with the output of an 'Xml_generator'. It thereby
presents an easy way to generate XML to be consumed locally.

The patch also add a deprecation mark to the original 'xml' accessor
because copying 'Xml_node' objects (here as return value) is dangerous.
The new 'with_xml_node' method should instead be used to access the XML
content stored in the buffer.
