5d56340568 vfs_lxip: return WRITE_ERR_WOULD_BLOCK on EAGAIN
Because all operations in lxip are non-blocking, return
WRITE_ERR_WOULD_BLOCK for data writes as done by read.

Note: This was not the case in the old plugin because 'write' was blocking
operation there.

1056c759fd vfs_lxip: propagate data file write error
All errors (as in the legacy version) are now propagated as WRITE_ERR_IO
(see Lxip_vfs_file_handle::write), which ultimately will lead to EPIPE
in libc's socket_fs. This also counts for EAGAIN leading to the fact
that partial writes are not supported for blocking sockets in libc, also
libc will not try a second time in case not all data has been written.

b30bacf86e lxip: shadow asm-generic/access_ok.h
The IP stack checks "user" pointer access, for example, for iov's using
'access_ok' which in turn calls '__access_ok'. The function checks if the
pointer is below TASK_SIZE_MAX, which is usually a big value on 64 bit
systems, but 3GB on 32 bit systems. Because the IP stack is mostly used with
Genode's libc, where pointers on some kernels (base-linux) can be >3GB and we
don't want to make an additional copy of each buffer/iov interacting with the
IP stack, we short circuit the function

1866520d6c dde_linux: build initcall_table.c after objects
The added hook 'OBJ_POSTPROC_SRC' gives us a way to post-process object

initcall_table.c generated by import-lx_emul_common.inc gets reliably

7ec08af6d9 usb: session renewal & new client API
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.

The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.

The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.

This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.

The adaptations necessary target the following areas:

* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
  reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
  with the new policy rules of the USB host controller driver

1dcc6fda6b lx_emul: improve motion-device handling in evdev
The key element of the improvement is differentiated processing of
events of the following device types.

  Mouse:       relative motion
  Pointer:     absolute motion (Qemu usb-tablet and IP-KVM devices)
  Touchpad:    relative motion via absolute touchpad coordinates
  Touchtool:   absolute motion (e.g., stylus)
  Touchscreen: absolute motion and finger (multi-) touch

Processing is done in two stages for one "input packet". First, all
events of the packet are recorded into the current evdev state with
device-type specific operations. Then, appropriate Genode input events
are generated from the accumulated evdev state in the submission stage
(again by device-type specific functions).

A simple version of tap-to-click was added to the touchpad support.

7e8661f8bf virt_linux: disable SMP for arm_v7 and change to tiny rcu
When SMP is enabled multicore specific instructions (e.g., pldw) are
generated. These are not supported and lead to invalid instruction
faults on uni-processor systems (like Cortex-A8). Therefore, we disable
SMP for arm_v7 in Linux code. This requires also a switch from the RCU
tree implementation to RCU tiny, which we shadow and dummy implemented.

651eb9d4f2 lx_emul/random: do not use jitterentropy in case initialization failed
Until now, in case 'jent_entropy_init' failed an error has been produced
and the following jitterentropy functions (i.e.,
'jent_entropy_collector_alloc') where called nevertheless. In case we
received a bad time source error, for example because the performance
counters are not working on the platform, the entropy collector did not return (endless
loop).

Therefore, this commit treats the failed jitterentropy initialization
not as an error but prints a warning about poor randomness quality and
stops using the jitterentropy library from this point on. The
'Jitterentropy::gen_random_u64' will in this case return the address of
a stack variable * some counter.

This is only a interim solution to make platforms work where performance
counters or TSC values do not exist/work.

1336b0a751 mmio: upper-bounds checks
The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).

That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.

Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.

The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.

The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.

Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.

1b4f7ae0d3 lx_emul: generate initcalls during build
Functions registered with 'module_init' (i.e., '__define_initcalls'),
'OF_DECLARE', and 'DECLARE_PCI_FIXUP_CLASS_FINAL' used to be static
constructors and had be explicitly registered using
'exec_static_constructors' before executing any Linux code.

With this commit we remove the constructor attributes from these
functions and create a global function pointer in the form of

__initptr_<name>_<id>_<counter>_<line number of macro>

'import-lx_emul_common.inc' will collect these '__initptr' symbols after
the compile step and generate a 'lx_emul_register_initcalls' function
that executes the functions pointed to. This step is now automatically
performed in 'lx_emul_start_kernel'. This way a call to
'exec_static_constructors' can be omitted in case there are no other
constructors in place.

-fno-omit-frame-pointer explicitly and in most cases leads to page
faults because non-pointer stack values are dereferenced during the
walk. The best we can do is to limit the backtrace walk to the stack of
the current thread to prevent page faults unrelated to the system state
without the use of the backtrace utility.

This commit introduces a printable Backtrace class usable in
Genode::log(), Genode::trace(), etc. The class is based on the new
function for_each_return_address(auto const &fn) that walks the stack in
its limits and calls fn() for each discovered return address on the
stack in the new os/include/os/backtrace.h. Archtecture-specific
stack-pointer retrieval and walk loops are implemented in dedicated
os/include/spec/<arch>/os/for_each_return_address.h files. Also, the
well-known Genode::backtrace() function (which logs the return-address
values) is provided for backwards compatibility.

68ac1347b9 lxip: configure thash/uhash entries to 2048
The number of hash entries for TCP/UDP corresponds to the number of
sockets managed by the stack. In case there are more sockets than
entries available, buckets will be created to compensate for the lack of
space. The default values for TCP (524288) and UDP (65536) are meant for
the in kernel that manages all sockets of the user land and leads
to very large hash table allocations (>20MB) during initialization.

Since on Genode a component has its own instance of the IP stack or uses
the VFS server, we do not need these kind of large default settings.

1e7116fcc1 lx_emul: manage page structs per buffer range
The management of Linux page structs is now tied to the life time of DMA
buffers. Thus, page structs are created when a buffer is allocated and
deallocated only when a buffer is freed - not on lx_emul_mem_free()
because DMA buffers are cached. Page struct refcounting was entirely
reworked in lx_emul/shadow/mm/page_alloc.c.

342e48115e lx_emul: replace USB devio API usage
The devio API in the Linux kernel promised to be a stable layer for our
USB host controller drivers, but the additional bookkeeping and dynamic
allocations increase CPU overhead in a way that we do not accept further.
Therefore, we go a step back and process DMA transactions directly in and
out of the packet stream from the clients.

62492f3cd2 lx_emul: do not reset ep in usb flush transfers
Certain USB devices do not react anymore after an endpoint reset
in the use case of USB devices passed through to a virtual machine.
When investigating the only USB session client that needs the
flush transfers request - namely the Qemu xhci model used in
VirtualBox - there seems to be no need to reset the endpoint in fact.
