5a1c47e943 Noux: simplify 'User_info' constructor
This patch removes the '_dup_str' function, which was unsafe due to a
missing check of the dst boundary.

The 'string.c' file contains a 'memcmp()' implementation which is needed
by the driver.

4a3d852b65 Core: Shared IRQ support for Nova/FOC/OKL4
Implement shared IRQs using 'Irq_proxy' class.

Nova: Added global worker 'Irq_thread' support in core and adapted Irq_session.

FOC: Adapted IRQ session code, x86 has shared IRQ support, ARM uses the old
model. Read and set 'mode' argument (from MADT) in 'Irq_session'.

OKL4: Use generic 'Irq_proxy'

Fixes issue #390

5549f6413b IRQ: Add base class for shared IRQs
Added generic 'Irq_proxy' class to core includes (ported from base-okl4). It can
be used to implement shared IRQ support for various base platforms. It will
generate one thread per IRQ and unblocks waiting clients (IRQ sessions) upon
interrupt receipt.

one program. So we expose it as part of the API in the os repository.

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.

4017e592f0 Compile PDBG() in release mode too
Formerly, GENODE_RELEASE just undef'd PDBG() which concealed bugs in
places PDBG was used, e.g., do to API changes. Unfortunately,
desparately disabling GENODE_RELEASE during bug hunt sometimes
introduced new errors. Now, PDBG is just a branch not taken but seen by
the compiler, which is able to produce warnings/errors when the API is
changed.

Fixes #378.

6862ab481a NOVA: drop special utcb handling of main thread
Unify handling of UTCBs. The utcb of the main thread is with commit
ea38aad30e at a fixed location - per convention.
So we can remove all the ugly code to transfer the utcb address during process
creation.

To do so also the UTCB of the main thread of Core must be inside Genode's
thread context area to handle it the same way. Unfortunately the UTCB of the
main thread of Core can't be chosen, it is defined by the kernel.

Possible solutions:
- make virtual address of first thread UTCB configurable in hypervisor
- map the utcb of the first thread inside Core to the desired location

This commit implements the second option.

Kernel patch: make utcb map-able
With the patch the Utcb of the main thread of Core is map-able.

Fixes #374

Noux actually uses the sp variable during thread creation and expects to be
set accordingly. This wasn't the case for the main thread, it was ever set
to the address of the main thread UTCB.

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

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.

55a8bae2f8 Noux: close all file descriptors on child exit
With this patch, when a child exits, all of its open file descriptors get
closed immediately. This is necessary to unblock the parent if it is
trying to read from a pipe (connected to the child) before calling
'wait4()'.

5c36639031 Fix UDP checksum calculation (fixes #360)
Missing parantheses around the calculation of last byte address in a UDP
Packet led to dereferencing the wrong value, thereby the UDP checksum
calculation failed, whenever an odd byte-count UPD packet was calculated.

resolution.

f5efbff19c Vancouver: map solely requested memory region
Don't map all memory of the VM at once, instead only the one permitted
by the memory model. Otherwise memory regions get mapped which must not,
where each instruction and memory access have to cause an exception in
order to emulate it step by step.
