#include <base/service.h>
base: avoid use of deprecated base/printf.h Besides adapting the components to the use of base/log.h, the patch cleans up a few base headers, i.e., it removes unused includes from root/component.h, specifically base/heap.h and ram_session/ram_session.h. Hence, components that relied on the implicit inclusion of those headers have to manually include those headers now. While adjusting the log messages, I repeatedly stumbled over the problem that printing char * arguments is ambiguous. It is unclear whether to print the argument as pointer or null-terminated string. To overcome this problem, the patch introduces a new type 'Cstring' that allows the caller to express that the argument should be handled as null-terminated string. As a nice side effect, with this type in place, the optional len argument of the 'String' class could be removed. Instead of supplying a pair of (char const *, size_t), the constructor accepts a 'Cstring'. This, in turn, clears the way let the 'String' constructor use the new output mechanism to assemble a string from multiple arguments (and thereby getting rid of snprintf within Genode in the near future). To enforce the explicit resolution of the char * ambiguity, the 'char *' overload of the 'print' function is marked as deleted. Issue #1987

Remove blocking calls from root and parent RPCs This is a redesign of the root and parent interfaces to eliminate blocking RPC calls. - New session representation at the parent (base/session_state.h) - base-internal root proxy mechanism as migration path - Redesign of base/service.h - Removes ancient 'Connection::KEEP_OPEN' feature - Interface change of 'Child', 'Child_policy', 'Slave', 'Slave_policy' - New 'Slave::Connection' - Changed child-construction procedure to be compatible with the non-blocking parent interface and to be easier to use - The child's initial LOG session, its binary ROM session, and the linker ROM session have become part of the child's envirenment. - Session upgrading must now be performed via 'env.upgrade' instead of performing a sole RPC call the parent. To make RAM upgrades easier, the 'Connection' provides a new 'upgrade_ram' method. Issue #2120

/* core includes */
base: remove include/spec/* other than ISA This commit moves the headers residing in `repos/base/include/spec/*/drivers` to `repos/base/include/drivers/defs` or repos/base/include/drivers/uart` respectively. The first one contains definitions about board-specific MMIO iand RAM addresses, or IRQ lines. While the latter contains device driver code for UART devices. Those definitions are used by driver implementations in `repos/base-hw`, `repos/os`, and `repos/dde-linux`, which now need to include them more explicitely. This work is a step in the direction of reducing 'SPEC' identifiers overall. Ref #2403

hw core: merge Kernel::Clock and Kernel::Timer With this, we get rid of platform specific timer interfaces. The new Timer class does the same as the old Clock class and has a generic interface. The old Timer class was merely used by the old Clock class. Also, we get rid of having only one timer instance which we tell with each method call for which CPU it shall be done. Instead now each Cpu object has its own Timer member that knows the CPU it works for. Also, rename all "tics" to "ticks". Fixes #2347
