os: manage/dissolve Signal_rpc_member in class

Instead of, passing responsibility to manage and dissolve Signal_rpc_member
objects at a corresponding entrypoint to the user, hand over entrypoint's
reference to the constructor, and do it in the constructor resp. destructor
of the class.

Vancouver: Clarify license headers

All source codes of the glue code between Vancouver and Genode that were
based on existing GPL code had already stated that Genode Labs is not
the sole owner of the code. To make the distinction between the Genode
OS framework and the glue code more clear, this patch removes the text
"is part of the Genode OS framework" from the glue code.

noux: add block device file system

Access to a block session is provided by using the block file system.
By specifying the label, each block session request can be routed to
the proper block session provider:

! <fstab>
! 	...
! 	<dir name="dev">
! 		<block name="blkdev0" label="block_session_0" />
! 	</dir>
! 	...
! </fstab>

In addition to this file system, support for the DIOCGMEDIASIZE ioctl
request was added. This request is used by FreeBSD and therefore our
libc to query the size of the block device in bytes.

Fixes #1010.
noux: add e2fsprogs-v1.42.9 package

Fixes #1029.
libc: add support for sysconf(_SC_PAGESIZE)

Fixes #1027
run: instruct 'exec' to ignore stderr output

Unless '-ignorestderr' is set on 'exec' in expect, any output on stderr
is interpreted as execution failure. In this case, 'create_iso' logs
some diagnostics but does not fail.

We repeatedly promote our ISOs to be bootable from USB storage.
Therefore, we have a hard dependency on 'isohybrid' and should fail in
the case that the tool is missing.
Arora: fix the demo launchpad configuration

This patch adapts the launchpad configuration of the Nitpicker plugin demo

Fix memory leak in Gallium EGL driver
