0dbb5e1696 Propagate 'Range_allocator::alloc_aligned' errors
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.

Related to issue #526.

42df6e3d01 libports: add test/libc_resolv target
libc_resolv is used by noux-pkgs and is only a runtime dependency but
therefore needs to be build.

05e60691cb Add missing libs
The eglgears application depends on 'sqrt'. With the old tool chain,
this symbol was resolved through the dependencies of the 'gallium'
library. This does not work anymore for the new tool chain.

A similar issue arised for avplay, where we need to explicitly
state the av components in the LIBS declaration of the target.

f635cc4a19 Python: use 'libc-rom' plugin
This patch removes the libc plugin of the Python port. The Python test
uses the 'libc_rom' plugin instead.

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

memcpy to copy PBUFs

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'.

f7dd8aa688 libports: adjust lwip's TCP_SND_BUF size

large but the TCP send throuhgput has increased noticeable (a few MiB/s

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.

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.
