In some situations, atexit handlers perform I/O (e.g., closing a file),
which entails the handling of signals. Should SIGTERM be pending, the
handling of this signal will in turn trigger the execution of atexit
handlers. To break this cycle, this patch removes atexit handlers from
the list before executing them. So no atexit handler is entered more
than once.
Fixes#5444
This patch moves the formerly hard-wired drag-and-drop handling
to the configuration level by introducing the actions "drag" and "drop".
To aid the robust handling of release events matching their
corresponding press events, the patch refines the policy-matching of the
current combination of keys against the hierarchy of <press> and
<release> nodes. If no policy for a concrete combination exists, a
release event also considers the policy of its matching <press> node.
This way, the regular drag-and-drop rules can be expressed as
<press key="BTN_LEFT" action="drag">
<release key="BTN_LEFT" action="drop"/>
</press>
This also works when releasing BTN_LEFT while pressing additional keys,
for which no policy exists.
With this change, the layouter supports the matching of multiple key
sequences instead of only one, thereby supporting multiple actions at
once and allowing for decoupling different user interactions in the
configuration.

Prevent errors like follows.
error: invalid cast from type ‘size_t’ {aka ‘long unsigned int’} to type ‘__u64’ {aka ‘long long unsigned int’}

Instead of freezing, return corresponding libusb error code if the
USB device got disconnected. Therefore, components using the library
can continue to work otherwise.

Core uses an instance of 'Pd_session_component' as a representative
for RAM/cap quota accounts used whenever session resources are
donated to core's services. All other facets of 'Pd_sesson_component'
remain unused. Core's instance of 'Pd_session_component' is hosted
at 'Core_env'. Upon its construction, all unused facets of
'Pd_session_component' are initialized by dummy arguments in 'Core_env'.
To overcome the need for dummy arguments, this patch splits the
accounting part of the PD-session interface into a separate
'Pd_account' interface. This gives us the prospect of narrowing
core's current use of 'Pd_session_component' by 'Pd_account',
alleviating dead code and the need for any dummy arguments.
Issue #5408
Replace the use of the global 'core_env()' accessor by the explicit
delegation of interfaces.
- For allocating UTCBs in base-hw, 'Platform_thread' requires
a way to allocate dataspaces ('Ram_allocator') accounted to the
corresponding CPU session, a way to locally map the allocated
dataspaces (core's 'Region_map'), and a way to determine the
physical address (via 'Rpc_entrypoint') used for the initial
UTCB mapping of main threads. Hence those interfaces must be
passed to 'Platform_thread'.
- NOVA's pager code needs to look up 'Cpu_thread_component'
objects using a map item as key. The lookup requires the
'Rpc_entrypoint' that hold the 'Cpu_thread_component' objects.
To make this 'Rpc_entrypoint' available, this patch adds
the 'init_page_fault_handing' function.
- The 'Region_map_mmap' for Linux requires a way to look up
'Linux_dataspace' objects for given dataspace capabilities.
This lookup requires the 'Rpc_entrypoint' holding the dataspaces,
which is now passed to 'platform.cc' via the new Linux-specific
'Core_region_map::init' function.
Issue #5408
Instead of repeatedly printing error messages when a device is not
available anymore, print an error once and then sleep forever.
There is no dynamic behaviour with respect to device availability
implemented in the libusb yet. Instead, you can manage libusb
components externally.
Ref genodelabs/genode#5401
When constructing an Usb::Interface and implicitly corresponding
Usb::Endpoint instances only select endpoints relevant for the
given alternate setting.
The libusb has to be changed to delegate the correct alternate
setting to the constructor too.

Instead of directly process URBs whenever a USBPacket arrives from
the Qemu ported XHCI layer, send a local signal to the I/O handler,
which will process the requests after leaving certain sensible
code pathes like usb_packet_complete. Otherwise, it might happen
that a packet, which was still marked as being queued gets already
completed, which leads to an assertion and hang of the library.
Fixgenodelabs/genode#5389
- add a check to detect if a different thread has
initialized the internal object in the meantime
- remove ENOMEM error since the 'Libc::Allocator'
is not supposed to throw exceptions
- remove init mutex from 'pthread_condattr_init()'
since there is no implicit initialization which
could happen in parallel like with mutex/cond/rwlock
Issue #5386
Because the implemantations for Lima and Vivante are linked into a
single library we cannot have two Gpu::Vram classes in the same
namespace. In case this happens any methods using the same signature are
weak symbols and the first one found by ld will be used = undefined
behavior.

The recent changes of the GUI stack (proper accounting of cap and RAM
resources by the window manager and nitpicker, output buffered at the
server side) require quota adjustments at various GUI-related places.

In multi-monitor scenarios, the mode is no longer a single rectangular
area but a panorama with potentially many captured rectangles. This
patch replaces the former 'mode' and 'mode_sigh' RPC by a new 'info'
ROM accessor.
