The 'black_hole' component provides dummy implementations of common
session interfaces.
At this time, only the 'Audio_out' session is provided if enabled
in the configuration of the component:
<config>
<audio_out/>
</config>
Issue #3653
* Switch mesa support from DRI to gallium
Supported drivers are
- softpipe (Sebstian Sumpf)
- iris for Intel GPUs (Alexander Boetcher)
- etnaviv for Vivante GPUs (Josef Söntgen)
* Mesa's generated files are placed into 'contrib/mesa-<hash>/generated'
and are cloned per default from a separate Git repo in order to avoid
hash updates upon package build. In case you need to generate files
yourself use
! prepare_port mesa GENERATE_FILES=1
issue #4254
Support for iris and etnvaviv
* entaviv:
- libdrm on FreeBSD is not prepared for !PCI (and libc our is missing
<sys/pciio.h>
- missing <sys/types.h> include in xf86drmMode.c
- etnaviv relies on linux header files - dummy in $(INC_DIR)
- IOCTL FreeBSD ↔ Linux have swapped IO/OUT bit
- O_CLOEXEC differs between FreeBSD ↔ Linux

According to spec the tail pointer points to the next qword instructions
which will be used by the software.

issue #4254
Superpages (2M, 1G) are not supported by now, but partially copied over code
from base-hw was around. Remove unused register definitions and remove
non-working super page code do avoid confusion.
issue #4254
Size argument of ggtt free range check is ignored, which leads to
overlapping allocations inside, which leads to unavailable IO-MEM exceptions
thrown by core.
issue #4254
Both, trace_logger and vfs_trace had their own trace_buffer.h. This
commit consolidates the existing implementations and provides the
resulting trace_buffer.h at 'include/trace/'. It thereby becomes part of
the trace api archive.

Driver code such as mfd-core.c may pass 0 as argument n to kcalloc,
which eventually results in an allocation size 0.
res = kcalloc(cell->num_resources, sizeof(*res), GFP_KERNEL);
Since 'res' is checked against NULL for success, kmalloc must not return
a NULL pointer in this case. The patch works around this issue by
forcing an allocation size of 1 byte in this case.
Issue #4253
Clock providers such as drivers/clk/sunxi-ng/ccu-sun8i-r.c don't use
regular init calls but declare their init functions via CLK_OF_DECLARE,
which fill the __clk_of_table. Linux populates the table statically by
using special sections declared in the linker script. In contrast, we
populate the table by expanding the macro to global constructor
functions.
The __clk_of_table is then processed by the call of of_clk_init(NULL).
Issue #4253
* Disable trace source and release ownership on subject destruction.
* Note, since the policy module is also destroyed on descruction of the
session component, the traced component must not access the policy
module when acknowledging the disabled state (else: page fault).
Fixesgenodelabs/genode#4247
If the trace subjects are not properly destructed when the TRACE client
disappears, enabled sources will be owned by a non-existing client.
In other words, when a TRACE client disappears all sources owned by the
client must be disabled.
genodelabs/genode#4247
test-trace always passed, although tracing was never enabled because the
trace subject was not within the first 32 subjects.
* increase number of queried subjects
* output error if trace subject was not found

With this commit, the NIC router DHCP client reads out the first DNS domain
name (DHCP option 15) if any from a DHCP reply that generates an IPv4 config
for a domain and stores the name together with the IPv4 config for that domain.
DNS domain names are reported via the new report tag '<dns-domain>' if the
'config' attribute in the config tag '<report>' is set.
Furthermore, the NIC router DHCP server becomes able to obtain a DNS domain
name from another domain that has a DHCP client dynamically (given the config
attribute 'dns_config_from' is set and no static DNS config is given) or
statically from its configuration (new config tag '<dns-domain>') and propagate
this name with DHCP replies (DHCP option 15).
The 'nic_router_dhcp_*' tests are adapted to test the new feautures.
The commit also gets rid of some mirrored files in
'test/nic_router_dhcp/manager'.
Fixes#4246
