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.

This commit adds a new configuration option, `dst_addr` to the
'sntp_client' that accepts either an IP address or a DNS hostname. If a
DNS hostname is provided, the 'sntp_client' will resolve the IP address
before each SNTP request. The 'dst_ip' configuration option is
deprecated but kept for compatibility until 'dst_addr' is fully adopted.
xsd/net_types.xsd: add Net_address type
sntp_dummy_rtc: adjust configuration to use pool.ntp.org

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.

The main user of libsparkcrypto in the past was the CBE block encryption
ecosystem. However, the CBE was replaced with the Tresor block encryption that
uses libcrypto instead.

This patch ultimatedly removes format strings from Genode's base API.
Users of the former base/snprintf.h and base/console.h headers may
use the free-standing 'format' library hosted in the ports repository.
Fixes#2064Fixes#3869
This little library implements rudimentary format-string support. It is
useful for porting 3rd-party code that ought not depend on a full libc.

Since the lwip library is used only by the vfs_lwip plugin, this patch
moves the Genode-specific support code local to the VFS plugin, easing
further simplification and allowing for a tighter integration with the
VFS plugin.
The recipes for api/lwip and src/vfs_lwip stay separate as both parts
use different licenses.
Issue #4697
This recipe combines the dummy_rtc_drv, which consumes a given time,
and provides the "Rtc" service to its clients with the simple NTP client,
which provides the current time to the RTC driver in regular intervals.
