The original use cases of the loader have long been covered by the
dynamic init. The only substantial client of the loader remained to be
the qpluginwidget. However, the qpluginwidget was supported only by the
Arora web browser. But the blending of plugins with websites ultimately
remained a tech demo, and Arora has been replaced by Falkon.

When more than one thread are accessing the DRM interface it is not wise
to use global locking, especially when a pthread is executing a batch
buffer and waits for a completion signal in the VFS-plugin. In case the
EP gets stuck in the global lock, no progress is made. Therefore:
* use _drm_mutex only where strictly necessary
* use special _exec_mutex to protect buffer execution (per context)
* print warning when two threads try to execute a buffer in the same
context

* add patch to retrieve PCI/Platform information from Genode side of the DRM

* add generated 'fourcc' file
* iris:

* add various I915_CONTEXT_PARAM* and I915_PARAM*
* allocate 'Buffer's starting with ID 1 (0 is invalid)
* enforce 48-bit-address limit on unmap also
* disable I915_EXEC_FENCE_ARRAY array check, because we do not support
sync objects right now and rendering in synchronous
* etnaviv:
* create 'Fenceobj' only *once* for each GPU context

For pbxa9, Qemu is started with only 256 MiB for foc but with 768 MiB
for base-hw. By reducing the RAM quota for all start nodes within the
remote scenario, each component gets enough RAM quota to breathe.
Such messages can occur by chance when killing 'echo' while the program
blocks in an IPC call. It gets killed nevertheless. So the message does
not hint at a failure of the test.
The dynamic buffer allocation increases the RAM demand slightly beyond
1M on seL4. Use 2M, as is already the default in pkg/terminal_crosslink.

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

This patch was back ported from upstream Mesa and generalizes the memory
management of buffer objects used by the binder. Before this patch the
binder was treated as a special case where buffer objects were allocated
with a simple "next block or wrap" allocator. With this commit the
binder now uses the vm_heap allocators as done by all other buffer
allocations which leads to issues with reference counting and object
destruction being resolved.
Original commit message:
We're moving towards a path where all contexts share the same virtual
memory - because this will make implementing vm_bind much easier - ,
and to achieve that we need to rework the binder memzone. As it is,
different contexts will choose overlapping addresses. So in this patch
we adjust the Binder to be 1GB - per Ken's suggestion - and use a real
vma_heap for it. As a bonus the code gets simpler since it just reuses
the same pattern we already have for the other memzones.
This commit replaces the mapping of DMA buffers and gets rid of the
bounce-buffer handling, which was introduced to prevent data
corruption noticed when utilizing USB storage with Windows 10 guests,
with accessing the buffers directly.
Due to the way Windows 10 at times manages its DMA memory (many small
pieces instead of few larger ones) the unbounded registry becomes a
problem when containing stale entries.
Changing the 'qemu-usb' implementation allows for using 'read_dma'
and 'write_dma' directly.
Fixes#5121.
In case the socket is non-blocking, a read with the MSG_PEEK flag set
has to return -1 and EWOULDBLOCK/EAGAIN in case no data is availble and
the socket is connected. Returning zero implies the socket is in
non-connected state. Therefore, check the connection state in this
situation and return accordingly.

This patch changes the unlink operation of the ram fs to defer the
destruction of a file until it is no longer referenced by any VFS handle.
When unlinked, the file no longer appears in the directory. But it can
still be opened and accessed.
With this change, a parent process of a Unix-like subsystem becomes able
to pass the content of an unlinked file to a forked child process. This
mechanism is required when using the 'exec' command in Tcl scripts.
Another use case is the 'tmpfile()' function.

Per Affinity::Location a system control cap can be requested. The capability
provides an RPC interface to request and set Cpu_state, as provided by the
former Pd::managing_system(Cpu_state) method. Invocation of those system
control capabilities then *can* (see below) be executed on the desired CPU
as described by Affinity::Location.
The system control cap will be invalid for kernels that don't support
system_control/managing_system functionality at all.
The system control cap will be ever by the same, e.g. ignoring the
Affinity::Location parameter, if the used kernel doesn't support or doesn't
require the feature to execute the system control per CPU.
The commit is a preparation step to add guarded and selective x86 MSR

Internally libyuv uses malloc & free for short time dynamic memory
allocation during image transformation. The converted images are
such large, that the Libc allocator will create and destroy new Genode
dataspace per image. In time sensitive code paths, the overhead can be
noticeable by the caller of the image transformation.
The patch adds the option to register callbacks in the libyuv library to
implement the image allocation by users of the library. They may implement
caching strategies to avoid the overhead, e.g. as seen with qemu-usb and
the webcam model.

Dynamically loading the `compat-libc` breaks `fork(2)` on Genode.
Switch `compat-libc` to a special api package that provides a source
file for statically linking the library, analogous to the `blit`
package. This also requires a quirk in Goa but should prevent breaking
`fork()` and removes the runtime and archive dependencies for Rust
packages using `compat-libc`.

Implement FBSD_1.0 versions of libc functions ('stat', 'fstat'). The
functions are versioned with @FBSD_1.0, and therefore, will not clash
with libc during linking. However, to be called by our dynamic linker,
the library must be before libc in the NEEDED section of the binary
using it. This requires the lib to be in front of libc in the LIBS
variable. The library currently will call libc 'stat' and 'fstat' by
looking up the symbols via 'dlsym'.

* Removes the <event> tag from all test package runtime files and replaces the
contained <timeout> and <log> sub-tags with the new tags <succeed> and
<fail>. If a <succeed> or <fail> tag has a content, it defines a log pattern
that should be recognized and render the test failed or successful. If a
<succeed> or <fail> tag has an attribute after_seconds that is not set to 0,
it defines a timeout after which the test should be rendered failed or
successful.
* Adapts the Depot Autopilot to support the new syntax in the test-package
runtime files. However, for now, the Depot Autopilot is kept compatible to
the old syntax as well. If the <events> tag is present, it is prioritized
over the new syntax.
