d762da8659 gui_session: allow return of View_capbility_error
This interface change gives GUI servers the freedom to allocate view
capabilities at the time of request instead of the creation time of the
view. This is useful because view capabilities are rarely needed.

f98c356efd gui_session: manage view ID at the client side
This patch moves the management of view IDs from the server to the
client side. The former 'create_view' and 'create_child_view'
operations do no longer return a view ID but take a view ID as
argument. While changing those operations, this patch takes the
opportunity to allow for initial view attributes. Combined, those
changes simplify the window manager while accommodating typical
client use cases with less code.

To ease the client-side ID management, the Gui::Connection hosts
a 'view_ids' ID space for optional use. E.g., the new 'Top_level_view'
class uses this ID space for ID allocation. This class accommodates the
most typical use case of opening a single window.

The 'alloc_view_id' RPC function is no longer needed.

d02a3d25d0 gui_session: replace Handle_registry by Id_space
This patch reworks the view-ID handling within the nitpicker GUI server
and the window manager. The namespace of view handles are now represented
as an Id_space. In constrast to the former "handles", which could be
invalid, IDs cannot be semantically overloaded with anything other than
an actual view reference. There is no notion of an invalid handle.
IDs are like C++ references (which cannot be a nullptr).

This change requires the code to be more explicit. E.g., the stacking of
a few at the front-most position can no longer be expressed by passing
an invalid handle as neighbor.

4e711d4738 gui_session: split alloc_view_handle, view_handle
Express the allocation of a new view handle by a dedicated RPC function
instead of passing an invalid view handle to the existing 'view_handle'
function.

This eliminates the notion of invalid view handles at the GUI session
interface, clearing the way for managing view handles via an Id_space.

f274ed549e gui_session: distinguish view-stacking operations
This patch eliminates the use of invalid view handles as special
Session::Command arguments. The TO_FRONT and TO_BACK operations
interpreted as invalid neighbor as top-most or back-most position.
Those corner cases are now expressed via dedicated commands. The
new stacking commands are FRONT, BACK, FRONT_OF, and BEHIND_OF.

While changing the command interface, the patch removes the OP_
prefix from the opcode values.

b0803eabdb gui_session: simplify input/framebuffer aggregate
- Rename framebuffer_session to framebuffer and
  input_session to input as those RPC interfaces are no longer
  meant to be used as stand-alone sessions.

- Host Connection::input and Connection::framebuffer as public
  members, thereby removing the use of pointers. This simplifies
  the client-sized code. E.g., '_gui.input()->pending()' becomes
  '_gui.input.pending()'.

9823b7dbd0 gui_session: remove C++ exceptions
To maintain ease of use at the client side, the OUT_OF_RAM and
OUT_OF_CAPS results are handled at the 'Gui::Connection' now.

Gui::Connection does not inherit the Gui::Session interface any longer,
which allows for the use of different result types.

1c148c7984 gui_session.h: distinguish child-view creation
This patch replaces the optional parent argument of the create_view
RPC function by a dedicated create_child_view RPC function. This

as a special case.

83ddc41d63 lighttpd: prevent invalid fdarray access
The fd event handling uses the fd to directly access the array slot and
expects the fds to be contiguous and capped.

Since the returned fds from our libc were much larger than expected,
because the libc itself consumes multiple fds when managing sockets,
using the fd in this manner leads to memory corruption.

This commit limits the maxfds to 63 and always allocates 1024 slots
in the fd-array.

2b3a2b875b wifi: fix double free during FW loading
The commit that added firmware loading via the VFS (see )
introduces a double-free bug where the memory that contains the
image is freed twice, once from the callback and once from the
work function.

As alle examined drivers call 'release_firmware' from the callback
function themselves, remove the erroneous 'kfree' call from the
work function.

eaadc6aad6 nova: support to run on e-core only SOCs
The code to group together SMT threads of one CPU and to move P-Core to
the beginning of Genode's affinity-space, did not consider to run on
SOCs with only E-Core CPUs.

Re-structure the code to support e-Core only SOCs.

Additionally, provide a fallback mapping in case of CPU id reordering problems.
Track faulty re-mapping and delay the reporting until core_log is initialized,
so that the warnings is visible to consumers, e.g. on Sculpt OS.

992b412be2 lx_emul: silently drop KEY_FN in evdev
The Fn key on keyboards should never be reported as real scancode event,
as it is just a hardware switch that changes the reported scancodes of
other keys. The behavior of Linux hid-apple.c is wrong as it on one hand
reports different scancodes for the same hard key depending on the Fn
state but sends the Fn press and release events too. Thus from now on,
we just drop KEY_FN events for all drivers as otherwise, scancodes
generated generated by Fn+key combinations would never be single-key
events on upper layers, for example KEY_FN + KEY_F12 on the Matias Apple
keyboard clone in the fixed issue.
