78497c03ca base-linux: enabled seccomp
base-linux uses seccomp to reduce the available system calls
to the minimum set needed to run base-linux. There are still
some syscalls that allow accessing global state which should
be further reduced.

The combination of seccomp and socket descriptor caps should
provide an intermediate level of security for base-linux
thereby enabling base-linux as a migration path from using
the Linux kernel to the use of microkernel-based Genode.

7f6b6d7e13 core-linux: make RAM quota configurable
Add the option to configure the RAM quota for core on base-linux.
The environment variable GENODE_RAM_QUOTA if it exists is interpreted

b078224753 Replace Genode::strncpy by Genode::copy_cstring
- Since Genode::strncpy is not 100% compatible with the POSIX
  strncpy function, better use a distinct name.

- Remove bogus return value from the function, easing the potential
  enforcement of mandatory return-value checks later.

0de54cddaa gdb_monitor: hide exceptions during create_thread
This patch is a workaround for the missing implementation of
'Pd_session::transfer_quota' interface by the GDB monitor's PD service.
The missing implementation becomes problematic with the changes of #3750
that enabled the cap-quota accounting for core's CPU service.

In regular scenarios without the GDB monitor, the client of
'Cpu_session::create_thread' deals with Out_of_caps or Out_of_ram by
upgrading the CPU session's cap and RAM quotas. This, in turn, results
in a sequence of 'transfer_quota' operations at the parent.

Since GDB monitor implements a custom PD service, these 'transfer_quota'
calls try to transfer quota between sessions provided by core and those
provided by the GDB monitor. This does of course not work. To fix this
issue, the GDB monitor needs a major overhaul. This patch side-steps
the problem by handing Out_of_caps and Out_of_ram from the debuging
target.

adb48b5c9e Libc: MSG_PEEK support
As discovered by Johannes Kliemann, peeking at buffered socket data
using 'recv' and 'MSG_PEEK' is not supported. Read a "peek" control file
from the socket directory to attempt to peek into buffers at the
socket_fs. Support for every feature of POSIX sockets cannot be
expected, but this one is trivial to implement.

f1427fc02a dde_bsd: remove configration attributes
The driver always opens the audio device in duplex mode, i.e.,
playback and recording. Setting the 'playback' or 'recording' attribute
only influnces the service announcement. Due to changes made in a more
recent OpenBSD release recording must be set enabled explicitly anyway.
Since we already provide the interface that mirrors the one used by
OpenBSD 1:1 in the configuration use that and the remove the additional
config attributes.

Fixes #3757.

42fddf8390 Cleanup shared-object support mechanics
The former ldso-startup static library (now called ldso_so_support) is
used to spice each shared object/library with local support code for the
dynamic linker (execution of static constructors and ARM-EABI).
Therefore, the library must be statically linked to each dynamic
library.

As a result recipes for dynamic libraries must always depend on the "so"
API, which makes ldso_so_support.mk and so_support.c available
independent of "base". Additionally, ldso_so_support is also provided in
the libc API to cut the dependency early for libc/posix libraries.

589b416ca8 Remove misleading "pipe" utility and test
If a "cat" tool as simple as the removed one is needed, it should be
implemented with Goa, only depend on libc/posix (*not* base), and be
named "simple_cat". Up to today, the misleading naming of the removed
tool, tricked me into believing "test-pipe" tests POSIX pipes, which it
did not!

64bc008c3a core: fix inconsistent state after failed 'trace'
This patch fixes the handling of the corner case where the allocation of
a trace buffer throws 'Out_of_caps' or 'Out_of_ram'. Under this
circumstance, the '_buffer' would still be flagged with the 'size',
which prevented any subsequent allocation attempt. This patch fixes the
problem by initializing the 'size' after the potentially throwing
allocation.

The problem triggered with the test-trace_logger after the accounting of
core's TRACE service (replacing the 'Allocator_guard' by
'Constrained_ram_allocator') became more accurate.

9d67f9fc8e Remove Allocator_guard
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.

The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.

The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.
