This CL introduces the Getrandom syscall. Allowing users of sufficiently new kernels (3.17) to detect when the operating system lacks enough entropy to generate cryptographic random data. See: http://man7.org/linux/man-pages/man2/getrandom.2.html As we have updated the syscall numbers, the Getrandom function can just be generated normally. The only other change is to mkerrors.sh to include the GRND_* flags for getrandom from <linux/random.h>. It is important to note that currently the mkerrors.sh script cannot actually be run as it has fallen behind the 4.10 kernel. The GRND_* flags were added manually. This was originally part of a larger commit that was split up.
