64245dde3a Avoid superfluous compiler warnings
GCC warns about uninitialized local variables in cases where no
initialization is needed, in particular in the overloads of the
'Capability::call()' function. Prior this patch, we dealt with those
warnings by using an (unreliable) GCC pragma or by disabling the
particular warning altogether (which is a bad idea). This patch removes
the superfluous warnings by telling the compiler that the variable in
question is volatile.

ad70160847 LWIP: Fix dead lock in semaphore back-end
Make sure unlock is called when 'global_mutex' reaches zero count. Add verbose
variable in order to disable some output. Disable irritating 'Overflow' messages
in 'sys_mbox_post' and 'sys_mbox_try_post' per default. This may happen and is
not an error, since the ring buffer is full and will be emptied eventually.
Remove priority from genode_org run script.

Should fix #347

825dc783e6 libc: Change malloc's allocator
Use slab allocators for small object sizes, do it the usual way otherwise.

This patch is related to #363. Using this optimization may be a viable
alternative to switching to the FreeBSD's malloc implementation.

7ca7b4417d lwIP: Rewrite NIC packet allocation
Use 'Nic::Packet_allocator', wait for acknowledgements if packet allocation
fails. Updated 'lwip.run' and 'genode_org.run' to support OMAP4 correctly. Use
memcpy to copy PBUFs

May resolve issue #347

97308f963a ffat_fs: work with absolute paths
The recently added 'Genode::Path' class makes it easy to create absolute
paths. With this patch the 'ffat_fs' server uses the 'Genode::Path' class
where possible instead of working with 'f_chdir()' and relative paths.
This also solves the problem reported in issue #355, which was caused by
storing a relative file name in the 'File' node.

Fixes #355.

3cfc691c77 libc_fs: handle 'Packet_alloc_failed' exception
With this patch, when a 'Packet_alloc_failed' exception occurs in the
'write()' function, the function waits for a packet acknowledgement and
the release of the packet and then tries the packet allocation again.

Fixes #348.

9651974448 Add stdcxx-4.6.1 to libports, fix #339
This patch adds libstdc++ to libports. With the previous version of the
stdcxx library, the build system used the C++ standard library that
comes with the compiler. This mechanism was prone to inconsistencies of
types defined in the header files used at compile time of the tool chain
and the types provided by our libc. By building the C++ standard library
as part of the Genode build process, such inconsistencies cannot happen
anymore.

Note that the patch changes the meaning of the 'stdcxx' library for
users that happened to rely on 'stdcxx' for hybrid Linux/Genode
applications. For such uses, the original mechanism is still available,
in the renamed form of 'toolchain_stdcxx'.

7f092be94c libc: allocate file descriptor sets on the stack
The 'fd_set' size calculation in the current version of the 'poll()'
function results in an  amount which is smaller than the size of the
'fd_set' data type. With this patch the file descriptor sets get
allocated as plain stack variables.

Fixes #335.

3084c6f500 TAR file system service
This patch implements a service which provides the contents of a tar
archive via the 'File_system::Session' interface.

Configuration:

<config>
	<archive name="tar_archive.tar" />
	<policy label="label_of_client" root="/rootdir/for/client" />
</config>

f2299abab5 libports: remove passwd functions from libc
Removes getpwent.c from build because the passwd facilities provided by
the FreeBSD libc will not be used anyway and add stub functions instead.
Now services which need these functions have to implement their own
(e.g. libc_noux).

a8609213a0 libc: Resolve subtle ambiguity in symlink creation
Apparently, GNU make 3.81 picks the generic '%.h' rule instead of the
more specific 'rpc/%.h' rule during the preparation of the libc.

Most of the libs are needed for DNS related stuff. Since we now

lead to undefined symbols so we remove them alltogther as build
dependency for the libc.

7a7adfbb63 Add mmap and nunmap to libc_noux, libc_fs
In the current form, only PROT_READ is supported. This case is emulated
by copying the file content into new allocated backing store. Even
though the performance benefits of mmap-using code will not be
preserved, code that relies on mmap can be executed via the libc_noux
or libc_fs plugins, i.e. lightttpd.

27a5edaf78 libports: disable call of lwip_loopback_init()
As of lwip-1.4.x this is not needed anymore because lwip
now always creates a loopback device. This plug-in will
be removed in the future but for now keep it around so
we currently do not need to update the other targets that
depend on it.

69fd7e1c32 libports: update lwip to STABLE-1.4.1-RC1
The new version works fine but there is an issue with connect()
that needs the included patch:

There is no actual handling of EALREADY in lwip. It sets errno
to EALREADY when the connection was established. Unfortunatly this
is really bad because most programs expect to receive errno EISCONN
if the connection was successfully established. So this behaviour
breaks Qt4 and several noux/net packages (like lynx) because those
programs end up in an endless loop trying to connect via an already
connected socket. The longterm solution would be fixing the wrong
behaviour in lwip (there are already bug-reports on lwip's mailinglist)
but for now, it works well enough to simple change lwip's err_to_errno
table to set errno to EISCONN when the connection was established.

8c306bde67 libports: add libc's rpc framework headers
Certain rpc headers are needed for compiling getaddrinfo.c. Unfortunatly
that means we have to generate _a few_ header files which we do when we
prepare the libc.

These header files need to be created before the symlinks. Also, some of
these header files depend on a patch. Therefore we apply the patches
first, generate the header files and in the end we create the symlinks.
