Use the Timer session duration for CLOCK_MONOTONIC and CLOCK_UPTIME.
Use the Genode::Duration object for passing internal time, it supports
sub-millisecond time and helps disambiguate units of time.
Fix#3018
Block and loop until application writes are sent or buffered in their
entirety. Do not call "tcp_output" directly, LwIP calls this procedure
internally and calling it again appears to disrupt the LwIP TCP state
machine.
Fix#3017
* Account all RAM/CAP quota of a session except quota for metadata used in
core. The latter is considered when asking if a session can afford to make
an operation but it does not get accounted to always be able to pay back all
quota when a session closes. The general accounting mechanism is moved from
atop of the allocators down to the level of RAM/RM session operations.
* report statistics about session objects and quota if <report stats="yes"
quota="yes"/> is configured. (default is yes if <report> is present)
Issue #2953
The VFS LwIP plugin is page-faulting on connect error because the LwIP
library frees a failed TCP protocol control block before calling the
error callback, and then the VFS plugin dereferences the PCB to free it
a second time. This problem was caused by a failure to follow
documentation during a transition from a C callback to a C++ method.
Fix#2972
When 'notify_read_ready()' is called during 'select()' and fails,
suspending can cause a deadlock when the libc IO response handler becomes
active and calls 'select_notify()', which tries to acquire the
'select callback list lock', which is already acquired by the suspended
'select()' call.
It seems possible to ignore a failed 'notify_read_ready()' call instead of
suspending. When the VFS plugin calls the IO handler later when the
notification request can be processed, the 'select_notify()' call of the
libc IO response handler will eventually call 'notify_read_ready()' again.
Fixes#2970
Implement the passwd database subroutines with single-user database.
This database is populated with a <passwd/> sub-node of the libc
configuration node. All fields of the "passwd" struct may be specified
with reasonable defaults provided for a "root" user. This allows a
libc-based component to spoof user information for the sake of porting
existing Unix software.
A test is provided at run/libc_getpwent.
Fix#2919
GNU tar interprets the passed time value in local time by default, which
lead to unstable hashes again. So, now provide a complete date/time
value incl. time zone.

There is a bug in the LwIP VFS plugin, the chained buffers used by Lwip
use sizes expressed in sixteen bits, and under conditions such as a read
of 1<<16 the higher bits are lost and the plugin performs a zero length
read, and the application interprets this as a closed connection.
Fix#2947
The PS/2 driver retries to get mouse-reset results for 700 ms, sleeping
after each attempt for 10 ms. So, the driver needs a Timer session now.
Fixes#2713
LwIP skips a packet copy by wrapping Nic stream buffer regions in LwIP
pbuf objects. Move from a fixed size array to a potentially unbounded
slab allocator for managing this buffer metadata.
Ref #2335
A 'QThread' can be reused when its execution is finished by calling
'QThread::start()' again. Before this commit, this created a new Genode
thread, but did not destroy a previously finished Genode thread first.
Fixes#2928
