300cdc435d expanding_report: make expandable for XML node generation
'generate(Xml_node node)', as used by the Sculpt manager, calls this
function instead of the lambda version. The 'report' function of the
'Genode::Reporter' does not throw an exception in case there is not
enough backing storage for the 'generate' request. Therefore, we have to
check this condition in a loop and call '_increase_report_buffer' in
case size limits are reached.

Patch by Norman Feske.

ec7d0efddf os: Drop unused Net::Dhcp_client::_alloc member.
This reference member is not used anywhere in the code. This prompts
clang to complain about it. Eliminate the member and all the plumbing

Clang really doesn't like char subscripts. I can't say I blame it. Fix
the warning by an explicit cast to unsigned.

To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.

3b8fe1b410 nitpicker: reflect seq number in clicked report
This patch makes nitpicker's "clicked" report useful for the detection
of clicks outside of any client. This is needed in situations where the
dialog should close when clicking outside its screen area. In the new
version, a click outside any client results in a report without a
'label' attribute. Furthermore, the report is augmented by the sequence
number of the click, which allows for freshness checks by the consumer of
the report (i.e., sculpt_manager).

479f2e0d1f trace_logger: remove false warnings from the log
This patch eliminates warnings that occurred as side effect of using the
'Session_policy' utility ("Warning: no policy defined for label...").
The new version uses the 'with_matching_policy' function instead, which
has the nice side effect of simplifying the error handling.

6eaeb61d58 os/session_policy.h: add 'with_matching_policy'
This patch makes the server-side policy-matching logic available outside
the 'Session_policy' class. Given that the new 'with_matching_policy'
function does not throw any exception, it gives server implementations
the freedom to avoid the C++ exception mechanism for the policy handling.

e4f62380d7 base: Pd_session::dma_addr, Pd_session::attach_dma
This patch enhances the PD-session interface with the support needed for
user-level device drivers performing DMA. Both RPC functions are
intended for the direct use by the platform driver only. If invoked for
PDs that lack the managing-system role, the operations have no effect.

The 'dma_addr()' RPC function allows the platform driver to request the
DMA address of a given RAM dataspace. It is meant to replace the
'Dataspace::phys_addr' RPC function.

The 'attach_dma' RPC function adds the given dataspace to the device
PD's I/O page table. It replaces the former heuristics of marking DMA
buffers as uncached RAM on x86.

With this patch, the UNCACHED attribute of RAM dataspaces is no longer
used to distinguish DMA buffers from regular RAM dataspaces.

4dfa7902db os: Input::Event:Seq_number event type
The new event type allows for the propagation of sequence numbers as a means to
validate the freshness of input handling. E.g., an menu-view-based application
can augment artificial sequence numbers to the stream of motion events supplied
to 'menu_view'. Menu view, in turn, can now report the latest received sequence
number in its hover reports, thereby enabling the application to robustly
correlate hover results with click positions.

22cce07ec8 fs_log: remove blocking call of get_acked_packet
This patch replaces formerly blocking packet-stream operations by
the explicit use of 'wait_and_dispatch_io_signal' for blocking.
It also removes a misleading comment that promised a fire-and-forget
behavior whereas the implementation relied on blocking I/O anyway.

df2e7fa842 vfs_block_file_system: remove Signal_receiver
The VFS block plugin used to depend on the blocking semantics of the
packet stream's 'get_acked_packet'. This patch replaces this dependency
by the use of 'wait_and_dispatch_one_io_signal'. However, in order to
implement this change, the custom instance of a 'Signal_receiver' had to
be removed as well.

To keep this patch as little invasive as possible, it does not touch the
direct use of the block session's packet stream, which should better be
replaced by the 'Block::Connection::Job' API.

7aa9cf9b37 uplink_client_base: add handlers for zynq_nic_drv
The zynq_nic_drv follows a zero-copy approach and thus uses the packet
buffers as DMA memory. In order to know when the RX DMA memory can be used
for another packet, a custom ack_avail_handler is needed.
Similarly, packets received from the Uplink session are not copied to a
DMA buffer but to directly passed on as DMA memory. For this purpose,
a a custom packet_avail handler is needed.

ac691eb229 file_system/util.h: remove packet-stream helpers
The 'read' and 'write' utilities are from a time before the VFS API
as os/vfs.h was available. They rely on the (now removed) blocking
semantics of the packet-stream interface.

The only remaining legitimate use case of the direct interaction with
the file-system session without VFS is the back end of gcov, which needs
a way to exfiltrate the statistical data using a channel that is
independent from the libc or the VFS.

84f8305cdf usb_report_filter: use VFS instead of fs session
This patch replaces the direct use of a file-system session via the
'file_system/util.h' helpers by the VFS using the os/vfs.h API. This
makes the component more flexible while removing the dependence from
read and write utilities of file_system/util.h, which happen to rely on
the (now removed) blocking packet-stream semantics.
