This patch largely reverts the commit "base: lay groundwork for
base-linux caps change" because the use of 'epoll' instead of 'select'
alleviated the need to allocate large FD sets, which motivated the
introduction of the 'Native_context' hook.

The topics are either covered by the Genode Founations book for by our
tools, in particular the integration of the prepare_port mechanism with
the run tool.
The mutex class is more restrictive in usage compared to
Genode::Lock.
- At initialiation time it is ever unlocked.
- No thread is permitted to lock twice. Warn about it
in case it happens.
- Only the lock onwer is permitted to unlock the mutex.
Warn about it and don't unlock the mutex in case it happens.
Issue #3612
Adding an explicit check clarifies at the first glance that the array
bounds are respected without needing knowledge about MAX_CAPS_PER_MSG
and L4_UTCB_GENERIC_DATA_SIZE (used for dimensioning 'mr').
Instead of hosting our outdated own fork, this commit now uses kernkonzept's
nowadays available github source repositories. This hopefully simplifies
updates, or cherry-picking single fixes.
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.

- kernel: disable forceful VM exit on task switch
- vm_session: adjust to kernel changes
Issue #3111
Track the dataspaces used by attach and add handling of flushing VM space
when dataspace gets destroyed (not triggered via the vm_session interface).
