9251b1ede8 rump: Port of the rump kernels to Genode
For further information see: http://wiki.netbsd.org/rumpkernel/. In this version
I ported the central rump components to Genode in order to take advantage of
NetBSD file system implementation. The new 'dde_rump' repository contains the
Genode version of the rump libraries and a 'rump_fs' server that implements
Genode file-system-session interface. Currently ext2, iso9660, and fat
file-systems are supported.

b7575319bf run: Add 'check_installed' command to run env
'check_installed' takes a command name as argument and tries to call 'which' in
order to find the command path. If that does not succeed, paths like '/sbin' are
'/usr/sbin' searched. On success the absolute path of the command is returned,
on failure 'exit' is called with an error message.

bd52e49698 os: remove startup lib from dynamic programs
All the pre- and post-processing of the startup lib around the main
function of a dynamic program is now done by LDSO. Hence LDSO directly
calls the main function of the program.

433a216919 base: Fix stack pointer alignment for ARM
After some research we found that the stack pointer on ARM platforms must be
at least double word aligned (See: "Procedure Call Standard for the ARM
Architecture" - 5.2.1.1). Since a 'call' on ARM will not result in a stack pointer
change (like on x86), the current behavior resulted in a 4 Byte aligned stack
only.

746011ee28 blk_cache: fix deadlock in allocator hierarchy
This commit generalizes the bit array in 'base/util/bit_array.h',
so that it can be used in a statically, when the array size is known
at compile time, or dynamically. It uses the dynamic approach of the
bit array for a more generalized version of the packet allocator,
formerly only used by NIC session clients. The more generic packet
allocator is used by the block cache to circumvent the allocation
deadlock described in issue #1059.

0056167157 liquid_fb: Improve resize handling
This patch make the handling of resizing the virtual framebuffer more
consistent. Liquid_fb keeps track of two sizes. The "next size" is the
size of the framebuffer handed out via the next call of 'dataspace'.
The "designated size" is the size as demanded by the user. The latter
size may be updated more often than the "next" size, depending on the
responsiveness of the framebuffer client to mode-change signals.

The patch also removes the synchronization with refresh calls because
the synchronization made the flickering artifacts worse when executing
nitpicker within liquid_fb. So it was not properly working anyway.
In the future, we might reimplement such a synchronization mechanism
when switching to the server API.

0b64328944 base: setup thread object for main thread in CRT0
For a main thread a thread object is created by the CRT0 before _main gets
called so that _main can already run in a generic environment that, e.g.,
catches stack overflows as a page-fault instead of corrupting the BSS.
Additionally dynamic programs have only one CRT0 - the one of the LDSO -
which does the initialization for both LDSO and program.
