* 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.
Fixes#4922
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.

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
