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
