Instead of using differing integer types use kernel_pid_t for process
identifier. This type is introduced in a new header file to avoid
circular dependencies.
When using socket stdio, add option to replay what has been written to
stdout while not connected (`-r`).
The implementation is to simply use the existing log file (which is
implicitly created when the option is used), and read from it until
EOF upon reconnect.

RIOT's gettimeofday needs to be called from syscalls.c to assure that gcc actually links it.
If an RTC if available and enabled it will be used instead.
closes#741
Old versions of the gnu libc uses calloc to allocate dymanic memory
when some error occurs in dlsym.
This results in a segfault as natives calloc wrapper has not been
initialized yet.
As this is a circular dependency and the libc can cope with this, we
just return NULL from the calloc wrapper and hope for the best.
Recent libc versions use a static buffer instead.
valgrind reported invalid reads/writes with glibc err[x]|warn[x] (in
glibc printf) when stdio had been redirected in between.
define _progname (pointing to argv[0])
wrap some libc functions that do system calls (terminal output)
wrap read/write with syscall guard
define real_read/write (next dynamic linker find for read/write)
guard system calls in remaining code
introduce native_internhal.h
throw out some debug statements that break things
clean up includes a bit
declare board_init in native_internhal.h
add -ldl to LINKFLAGS for cpu/syscalls
