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.

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.

b8beba5bf3 ldso: Support for setting global object values
Make 'set_program_var' accessible outside of 'rtld.c'. Also, compile
dynamically linked programs with the '-fPIC' option. Doing not so,
yields to program-global symbols being put in the '.symtab' section
(which can be stripped) only. In order to get access to global
variables from the dynamic linker, the symbols need to reside within
the '.dynsym' section additionally. Hence the '-fPIC'.

148206d757 rpi: Framebuffer and platform drivers
The platform driver is used to access the features provided by the
Videocore mboxes, i.e., power configuration and framebuffer setup. The
framebuffer driver uses the platform interface to setup a screen mode of

435bdd5755 dde_linux: Support for Raspberry Pi
At the current stage, the USB HID and storage drivers are prinicpally
working but not stable. If interrupts are not processed fast enough,
devices will get sporadically disconnected.

The USB host-controller driver is not part of the normal Linux kernel.
For this reason, we need to download it separately. There exists a
'prepare_rpi' rule in the 'dde_linux/Makefile' to automate this process.

8243329ad4 os: Move Genode::Config into 'config' library
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.

ce58a63fb6 Remove 'epit' from generic i.MX platform spec
Remove the 'epit' variable from the generic imx31 and imx53 specification,

Moreover, fix some const-ness issues in the platform_timer implementation
for the EPIT timer.

though, there does not seem to be any demand for it.

fae63f4fa9 Merge base libraries into a single library
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.

Hereby, the base libraries have been reduced to the following few
libraries:

- startup.mk contains the startup code for normal Genode processes.
  On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
  identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
  processes

Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.

1947d08e78 Use the host c++ for linking hybrid applications
Some shared libraries of the host system contain search paths for finding
other needed shared libraries. These paths get evaluated only by a native
linker. To find all needed shared libraries, with this patch, the host
linker is used to link hybrid applications.

Leave board drivers in 'base/include/platform'.

Rework structure of the other drivers that were moved to
'base_hw/src/core' and those that came with the trustzone support.

Beautify further stuff in 'base_hw'.

Test 'nested_init' with 'hw_imx31' (hardware) and 'hw_panda_a2' (hardware),
'demo' and 'signal' with 'hw_pbxa9' (qemu) and 'hw_vea9x4'
(hardware, no trustzone), and 'vmm' with 'hw_vea9x4'
(hardware, with trustzone).

c99dd8fdf8 Use 'CURDIR' make variable in Genode make files
The bash-builtin 'pwd' command uses the 'st_dev' and 'st_ino' members of
the 'stat' struct to compare the path from the 'PWD' environment variable
with the path returned by 'getcwd()'. These members don't get set
correctly in Noux and therefore the 'pwd' command sometimes returns wrong
results when building Genode in Noux. With this patch the 'CURDIR' make
variable gets used instead of calling 'pwd'.

Fixes #454.

1483f1032d Remove broken compiler check
The 'build.mk' file checks if the tool chain to be used supports the
'-static' and '-fno-stack-protector' flags, but this check always fails
for the current Genode tool chain because it cannot create executable
files without explicitly specifying the 'crt0' and library files to be
linked, which the check doesn't.

This patch removes the compiler check.

Fixes #358.

6994f6a8c5 Fix binary size for 64bit
Every 64-bit binary is effectively 4M too big currently [0]. The GNU linker ld
aligns the text section of the binary to the maximum page size. On i386
the default section alignment is fixed typically to 4K.

Avoid wasting mainly 4M on x86_64 by telling the linker the max page size to
be 4K.

ae6257dce1 Use NOVA microkernel from github, add 64bit
Use git to get recent kernels from github. Adjust NOVA patch to compile
with recent github version. Patch and use makefile of NOVA microkernel
to avoid duplicated (and outdated) makefile in Genode

Furthermore, this patch adds support for using NOVA on x86_64. The
generic part of the syscall bindings has been moved to
'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific
parts are located at 'base-nova/include/32bit/nova/syscalls.h' and
'base-nova/include/64bit/nova/syscalls.h' respectively.

On x86_64, the run environment boots qemu using the Pulsar boot loader
because GRUB legacy does not support booting 64bit ELF executables.

In addition to the NOVA-specific changes in base-nova, this patch
rectifies compile-time warnings or build errors in the 'ports' and
'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver
builds for 32bit only and needed an adaptation to NOVAs changed
bindings)

42b7c01685 Unify policy name for Native_capability_tpl.
This commit unifies the policy name for the template argument for
Native_capability_tpl to Cap_dst_policy, like suggested by Norman in the
discussion resulting from issue #145. Moreover, it takes the memcpy
operation for copying a Native_capability out of the template, which is
included by a significant bunch of files, and separates it in a library,
analog to the suggestion in issue #145.

b1b59fe8a6 Support for building all libs via 'make lib'
Normally, the build system creates libraries as mere side effects of
building targets. There is no way to explicitly trigger the build of
libraries only. However, in some circumstances (for example for testing
the thorough build of all libraries) a mechanism for explicitly building
libraries would be convenient. This patch implements this feature. It
consists of two changes.

The new pseudo target at 'base/src/lib/target.mk' gathers all libraries
that are available in all repositories specified for the build directory
and makes its target depend on them. This way, by building 'lib', all
libraries would be traversed. However, in the (likely) situation that
those libraries include one or more invalid libraries (libraries with
unsatisfied build requirements), the build system would skip the target.

Hence, the second change introduces a new condition 'FORCE_BUILD_LIBS'
to the build system. By setting this variable to 'yes' in the 'target.mk'
file, we let the build system to traverse library dependencies for
all valid libraries regardless of the presence of any invalid library.
