ed58040794 Define 'TZ_MAX_TIMES' as 1
This patch defines 'TZ_MAX_TIMES' as 1 when building 'localtime.c' to avoid
a big stack allocation in the 'tzload()' function.

Fixes #250.

d9d22fbf75 Pistachio: fix usage of wrong python version
The CML2 configuration system calls 'evn python' and expects version
2.x. So we check if python2 is installed when preparing Pistachio and
use the found version instead.

Fixes #264.

cdb1c6f203 Disable 'time_t' type size tests in findutils
Some type size tests in the findutils source code expect the 'time_t' type
to be of the same size as the 'long' type, whereas the Genode libc defines
it as '__int64_t' for ARM. This patch disables these tests.

Fixes #262.

e8b1b6f6da Fiasco.OC: fix run-environment for ARM platforms
Eliminate prints to stderr for normal messages, because it leads to exceptional
returns in TCL-scripts e.g. when run-script is triggered by the autopilot even
if the script's return code itself will be zero.

3e9d5c532c Enable drivers for foc_x86_64 while builddir creation
In the create_builddir script the foc_x86_64 platform was missing
when adding x86-drivers to the etc/build.conf file. This lead to
failed run-scripts initiated by the autopilot tool.

2da030d22e loader: Qualify size_t usages
The compiler complained about ambigous references when compiling a
lx_hybrid program using the loader session.  Here are some error
messages:

genode/os/include/loader_session/loader_session.h:72: error: reference to 'size_t' is ambiguous
/usr/lib/gcc/i486-linux-gnu/4.4.5/include/stddef.h:211: error: candidates are: typedef unsigned int size_t
genode/base/include/base/stdint.h:25: error:                 typedef unsigned int Genode::size_t

genode/base/include/base/stdint.h:25: error:                 typedef unsigned int Genode::size_t

This commit qualifies size_t using the Genode namespace which fixes
the compilation.

c56c9f586d NOVA: use grub instead of pxe
Make pxe optional and use by default grub.
For that to work we use objcopy to repack the elf64
file into elf32.

With this commit more tests succeed. Most
tests use 64M and with that pulsar even does not start
the hypervisor. With 96M more test run however that would
mean to adjust most of the run scripts ...

Without this patch the compilation failed with:

4534d656a8 NOVA: Improve stability of process destruction
The UTCB of the thread cleaning up thread objects has been unmapped.
However the UTCB of the destroyed thread must be unmapped.

Objects must explicitly be made unreachable before cleaning up. The
server and pager objects must be unreachable before they can be freed.
Both object types are threads. Revoking the thread(EC) cap on NOVA
doesn't mean that the thread stops executing. All portals pointing to a
thread are still reachable by clients even if the last EC cap is gone in
user land. So it must be taken care that no portals are pointing anymore
to a thread when the associated objects are getting destroyed. This
commit handles this.

Additionally, even if the last portal is gone - there can be still an
ongoing request handled by such server/pager object/threads. For each
such object an additional portal is created. This object is called
'cleanup portal' and is only local to the object. After all portals are
revoked the cleanup portal is called. When the call returns we know that
nobody is anymore handled by the object since all remotely available
portals are gone.

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)

1bf7967463 Noux terminal file system
This patch adds a new "terminal" file system type to Noux, which allows to
create a "character device" file that is connected to a Genode 'Terminal'
service.

The 'Terminal' session created by the file system has the label
"noux(terminal_fs)" to distinguish it from the 'Terminal' session
created by Noux itself.

288fd4e56e Add support for allocating DMA memory
This patch extends the RAM session interface with the ability to
allocate DMA buffers. The client specifies the type of RAM dataspace to
allocate via the new 'cached' argument of the 'Ram_session::alloc()'
function. By default, 'cached' is true, which correponds to the common
case and the original behavior. When setting 'cached' to 'false', core
takes the precautions needed to register the memory as uncached in the
page table of each process that has the dataspace attached.

Currently, the support for allocating DMA buffers is implemented for
Fiasco.OC only. On x86 platforms, it is generally not needed. But on
platforms with more relaxed cache coherence (such as ARM), user-level
device drivers should always use uncacheable memory for DMA transactions.
