df71e02ef6 alarm: fix bug in _setup_alarm
We did not set the correct now_period previously but it wasn't conspicuous
because the bug triggered not before a full period had passed which on most
platforms is a pretty long time.

28004bc9e6 timer: limit rate of handling timeouts
Ensure that the timer does not handle timeouts again within 1000
microseconds after the last handling of timeouts. This makes denial of
service attacks harder. This commit does not limit the rate of timeout
signals handled inside the timer but it causes the timer to do it less
often. If a client continuously installs a very small timeout at the
timer it still causes a signal to be submitted to the timer each time
and some extra CPU time to be spent in the internal handling method. But
only every 1000 microseconds this internal handling causes user timeouts
to trigger.

If we would want to limit also the call of the internal handling method
to ensure that CPU time is spent beside the RPCs only every 1000
microseconds, things would get more complex. For instance, on NOVA
Time_source::schedule_timeout(0) must be called each time a new timeout
gets installed and becomes head of the scheduling queue. We cannot
simply overwrite the already running timeout with the new one.

226fcbc02f Remove remote shell support from libc
The remote shell facilities are past deprecation and there is an
obligation to prevent their use rather than to support them. This patch
removes the related function definitions from 'unistd.h', which have not
been been included in the Genode libc ABI regardless.

8ca63d4a6e libc: reintegrate libc_resolv library
Remove getaddrinfo and freeaddrinfo from the Libc::Plugin and get rid of
the extra libc_resolv library. Remove getaddrinfo/freeaddrinfo symbol
hiding patch for FreeBSD sources. Remove libc_resolv from Makefiles and
run scenarios.

7b9edcf90c lxip: fix timer deletion and modification
Linux del_timer() and mod_timer() return if the timer was pending before
the modification. Additionally, these functions are potentially called
from handler function of the timer to modify and, therefore, checking
for timeout != INVALID_TIMEOUT is not sufficient as the timeout is
indeed valid when the handler is executed.

f04ef8ed40 run: align data after last boot module
In the image.elf file, the very last boot module is followed
by arbitrary other core-local data. Since those boot modules are
exported as page-granular dataspace to the outside of core via core's
ROM service, we need to ensure that the last page is padded with zeros.

6d361b337b input/root.h: support re-opening of sessions
This patch fixes an aliasing problem of the 'close' method signature
that prevented the Input::Root_component::close method to be called.
This way, the event-queue state was not reset at session-close time,
which prevented a subsequent session-creation request to succeed. With
the patch, input servers like ps2_drv, usb_drv that rely on the
Input::Root_component support the dynamic re-opening of sessions. This
happens in particular when using a dynamically configured input filter.

3f37a12e2d timer connection: fix mixing of time sources
We update the alarm-scheduler time with results of
Timer::Connection::curr_time when we schedule new timeouts but when
handling the signal from the Timer server we updated the alarm-scheduler
time with the result of Timer::Connection::elapsed_us.  Mixing times
like this could cause a non-monotone time value in the alarm scheduler.
The alarm scheduler then thought that the time value wrapped and
triggered all timeouts immediately. The problem was fixed by always
using Timer::Connection::curr_time as time source.

6bfd4f4276 gems: driver-manager subsystem for PC platforms
This is a drivers subsystem that starts the most fundamental
(framebuffer, input, block) device drivers dynamically, depending on the
runtime-detected devices. The discovered block devices are reported
as a "block_devices" report.

ea21576eac bash: make dependency from ld.lib.so explicit
This patch is a workaround for the apparent problem that noux
applications, which perform execve, implicitly use functionality from
the dynamic linker, not explicitly via the libc. If the binary lacks the
dependency information, noux will fail on the execve attempt. The latter
is the case when the noux package is built as a depot archive where
library dependencies are not traversed over multiple levels.
