This patch adds a switch to internal poll function in libssh that
allows to force this function to immediately return without actually
polling for data and in consequence processing this data. This switch
is used to avoid calling callback functions when flushing output
streams which caused locks due to recursive access to internal
ssh_terminal sessions registry.
Issue #4258
This patch allows to replace sftp packet read and write with
completely asynchronous versions needed to properly hook in existing
ssh_terminal implementation.

* 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
issue #4254
- API packages for: libusb, libuvc, and libyuv
- Source packages for: API packages + USB webcam app
- Meta package for USB webcam
- Raw package for USB webcam configuration

triggers using -O0 with test-libc_integration:
libc_integration/main.cc:146: undefined reference to `std::istream::operator>>(unsigned long&)'

Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
In case of contexts blocked in select() the monitor updates the
file-descriptor status, but if the entrypoint is just blocked for the
select handler, the status must be updated explicitly on
dispatch_select().
There is a type mismatch as in the FreeBSD contrib code the type of the
request is 'unsigned long'. So far, only I/O controls where the request
falls into the signed range where used and this was not a problem.
Some of the SNDCTL requests, however, have the bit set.
Fixes#3887.
This patch untangles the interplay of the base library and the libc
during the exit handling.
- The CXA ABI for the atexit handling is now provided by the libc.
For plain Genode components without libc dependency, __cxa_atexit
is a no-op, which is consistent with Genode's notion of components.
- The 'abort' implementation of the base library no longer calls
'genode_exit' but merely 'sleep_forever'. This way, the cxx library
no longer depends on a 'genode_exit' implementation.
- The libc provides 'atexit' support by storing metadata on the
libc kernel's heap now, thereby eliminating the former bounded
maximum number of atexit handlers.
- Shared-library dtors are no longer called via the atexit mechanism
by explicitly by the dynamic linker. This slightly changes the
call order of destructors (adjustment of the ldso test). Functions
marked as destructors are called after the atexit handlers now.
- The libc executes atexit handlers in the application context,
which supports the I/O operations in those handles, in particular
the closing of file descriptors.
Fixes#3851
* switch to fork of the Ada runtime provided by m-stein
* switch to a Ada-runtime state that provides the Exp_Int package (exponential
function on integers)
* adapt spark lib, symbols, and recipes to incorporate the Exp_Int package
Fixes#3848
This commit puts all C++ runtime/support symbols of ld.lib.so in a
dedicated section of base/lib/symbols/ld and mirrors the section to
libports/lib/symbols/libc. So, the libc ABI resolves potential C++
runtime dependencies of base-ABI-agnostic components at link time. The
runtime resolution is done by the linker by symbol lookup in ld.lib.so.
Issue #3720
The function is exposed in libc headers provided by Genode, the code for
the function is being compiled and actually works, but the symbol is
missing from the symbols file resulting in linking failures. Add it to
the libc symbols file.
