e143084b04 base: fix warning in RPC framework
The recent change of the TRACE session interface triggered the
following warning:

/home/no/src/genode/repos/base/include/base/ipc.h:79:4: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
    *reinterpret_cast<T *>(&_sndbuf[_write_offset]) = value;
    ^
In file included from /home/no/src/genode/repos/base/src/core/include/trace/session_component.h:19:0,
                 from /home/no/src/genode/repos/base/src/core/trace_session_component.cc:15:
/home/no/src/genode/repos/base/include/base/rpc_server.h:132:42: note: ‘ret’ was declared here
     typename This_rpc_function::Ret_type ret;

The warning occurs for basic return types (like size_t), which are
indeed not initialized. The variable gets its value assigned by the
corresponding 'call_member' overload, to which the variable is passed as
reference. But the compiler apparently is not able to detect this assignment.

Declaring 'ret' with a C++11-style default initializer fixes the warning.

5d678dba9e core: throw Trace::Out_of_metadata in subjects()
While importing trace sources as trace subjects into a TRACE session,
the session quota might become depleted. The TRACE session already keeps
track of the session quota via an allocator guard but the 'subjects' RPC
function missed to handle the out-of-memory condition. This patch
reflects the error condition as an 'Out_of_metadata' exception to the
TRACE client. It also contains an extension of the trace test to
exercise the corner case.

959572968d core: provide thread exec times via TRACE service
This patch enable clients of core's TRACE service to obtain the
execution times of trace subjects (i.e., threads). The execution time is
delivered as part of the 'Subject_info' structure.

Right now, the feature is available solely on NOVA. On all other base
platforms, the returned execution times are 0.

ef9c745e42 ldso: add memcpy and memset to symbol.map
On ARM, the compiler generates calls to memcpy and memset. Most
dynamically linked programs use the libc, which provides these
functions. However, if a dynamically linked program does not use the
libc (e.g., noux/minimal or the new version of cli_monitor), those
symbols remain unresolved. By adding them to ldso's symbol.map, the
dynamic linker will resolve them with the functions of the cxx
library, which is part of the dynamic linker.

554146d39c base: enforce ram_quota donations to be consistent
For several basic sessions that core provides default ram quota values
exist in the form of enum values. They are used e.g. by init to deduce
session costs. Unfortunately they were not used when actually establishing
the session, which lead to inconsistencies.

3a378bb970 libc_noux: remove dependency on 'platform_env.h'
Currently, libc_noux includes the 'base/src/base/env/platform_env.h' file
to be able to reinitialize the environment using the 'Platform_env'
interface. For base-linux, a special version of this file exists and the
inclusion of the generic version in libc_noux causes GCC 4.9 to make wrong
assumptions about the memory layout of the 'Env' object returned by
'Genode::env()'.

This commit moves the reinitialization functions to the 'Env' interface to
avoid the need to include the 'platform_env.h' file in libc_noux.

4736488d99 core: change order of _export_ds and _clear_ds
On seL4, we need to convert untyped memory to page frames before being
able to use it as normal memory. There already exists the hook function
'_export_ds' that is principally suitable for such tasks. It is
currently solely used on Linux where we have to create a file for each
dataspace. To make the hook useful also for seL4, we need to call
_export_ds prior _clear_ds. Otherwise, we would try to clear memory that
is still untyped.

98def2488a thread: move Thread_base::myself() to separate file
The thread library (thread.cc) in base-foc shared 95% of the code with
the generic implementation except myself(). Therefore, its
implementation is now separated from the other generic sources into
myself.cc, which allows base-foc to use a foc-specific primitive to
enable our base libraries in L4Linux.

c9272937e7 CPU session: apply quota via relative weightings
Physical CPU quota was previously given to a thread on construction only
by directly specifying a percentage of the quota of the according CPU
session. Now, a new thread is given a weighting that can be any value.
The physical counter-value of such a weighting depends on the weightings
of the other threads at the CPU session. Thus, the physical quota of all
threads of a CPU session must be updated when a weighting is added or
removed. This is each time the session creates or destroys a thread.

This commit also adapts the "cpu_quota" test in base-hw accordingly.

0fd53c7fe4 Extract numeric string arguments with the correct signedness
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.

With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.
