2f357a7224 Firewall-friendly download methods for contrib src
After this commit "make prepare" uses HTTP, HTTPS, or FTP where possible
fvor downloading third-party source codes. This prevents problems with
strict firewall rules where only selected ports are usable.

Unfortunately, git.l4android.org does not support Git via HTTP and,
therefore, the sources need a working Git port (9418).

Fixes #443.

837f913094 Noux: more useful gettimeofday() implementation
There are certain programs that need gettimeofday(), e.g.
network-related tools like ping(1) etc. but also filesystem-related
programs like find(1) etc. and of course time-related programs like
date(1).

As there is currently no interface in Genode for actually using clock
devices like RTC on x86 (though there is a driver for it) we "abuse"
the timeout_scheduler thread to at least provide flow-of-time.

Noux: add clock_gettime() implementation

For now, only CLOCK_SECOND is supported.

Noux: add utimes() dummy

ae8c464495 GDB monitor: move thread iterator declarations
This patch moves the thread iterator function declarations in GDB
monitor's 'Cpu_session_component' above the 'CPU session interface'

6aa05e8d46 Noux: add noux-pkg/lynx
Explanation why --disable-rpath-hack is needed:

When building on pistachio_x86 $(LDFLAGS) contains '-L[...]/l4/lib'
which will be transformed by autoconf to '-rpath [...]/l4/lib'.
Now the problem at hand is that we pretend to be FreeBSD when we are
actually not. So autoconf assumes it is valid to use '-path'  when it
is actually not.

Also we use zlib for (de)compressing gzipped streams/files instead of
calling gzip as this currently somewhat buggy.

a77c3dffd0 Noux: add user information support (struct passwd)
There are certain programs which need the information that is stored in
'struct passwd'. This commit introduces configurable user information
support to NOUX.

One can set the user information via <user> in NOUX config:

! <config>
!   <user name="baron" uid="1" gid="1">
!     <shell name="/bin/bash" />
!     <home name="/home" />
!   </user>
! [...]
! </config>

When <user> is not specified default values are used. Currently these
are 'root', 0, 0, '/bin/bash', '/'.

Note: this is just a single user implementation because each Noux instance
has only one user or rather one identity and there will be no complete
multi-user support in Noux. If you need different users, just start new
Noux instances for each of them.

ae524e4beb Noux: add timeout handling to select()
Previously there was not actual timeout handling. If a select() call
set an timeout it would be set to zero instead and was always handled
as blocking i/o. While this works fine for file descriptors which
will be triggerd externally (for example vim through terminal i/o) it
does not work at all for socket descriptors and network operations in
general.

So this commit introduces proper timeout handling and changes the
behaviour of SYSCALL_SELECT so that it now returns more than just
one descriptor at a time.

noux/minimal and noux/net now depend on thread and alarm libraries.

a7235d2411 NOVA: Use Genode interfaces to bootstrap Vancouver
Since no kernel objects can be created anymore outside Genode::core,
the Vancouver port must be adjusted to use solely the Genode interfaces.

The Vcpu_dispatcher creates all portals via the cpu_session interface and
uses the feature to setup a specific receive window during a IPC (the
cap_session::alloc IPC) to place to be received/to be mapped capability
(virtualization exception portal) at the designed indexes.

The actual vCPU thread extends from a normal Genode::Thread and extends it
by specific vCPU requirements, which are a larger exception base window and
the need by Vancouver to place the SM and EC cap at indexes next to each other.

d28465cb3a Noux: fix missing mode propagation
When opening a new file, a new Fs_vfs_handle is created but with the
initial mode set to 0 which is not expected by functions like fdopen()
that check if the original flags given to the open() call match the
returned ones on the used fd.

Fixes #289.

1b8fd4aa44 GDB for Noux
With this patch the 'GNU Project Debugger' (GDB) can be built for Noux.

The included run script connects GDB and GDB monitor via a cross-link
terminal and allows interactive source-level debugging of the GDB monitor
test application on Genode.

Fixes #280.

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.

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)

Fixes #233, fixes #234

In 'Fs_file_system::open()' the call of '_fs.dir()' can throw a
'File_system::Lookup_failed' exception, which gets explicitly caught
with this patch.
