CL 204418 adds functions PtraceGetRegSetArm64 and PtraceSetRegSetArm64 to file
zptrace_armnn_linux.go, both of which depend on type Iovec. The definitions of type
Iovec on linux arm and arm64 are different, but file zptrace_armnn_linux.go is
shared by them. So these two functions cause compilation errors on linux arm. This
patch fixes this error by moving these two functions into a separate file.

Since arm64 GNU/Linux version 2.6.34, PTRACE_GETREGS was replaced by PTRACE_GETREGSET,
in order to get or set the general purpose and floating-point register values,
PTRACE_GETREGSET/PTRACE_SETREGSET request type and a proper "NT_XXX" constant values
should be used. For the sake of not breaking the existing API, we added two functions
PtraceGetRegSetArm64 and PtraceSetRegSetArm64, they take an additional argument "addr",
and use PTRACE_GETREGSET and PTRACE_SETREGSET request types respectively.

Add syscall wrappers, error constants and types for linux/riscv64
Switch docker image to Ubuntu 18.10 in order to get qemu supporting
riscv64. Also set the uname release string for qemu to 4.15 (the first
Linux kernel version with riscv64 support), because otherwise running
the generating C program in mkerrors.sh on a host with an older kernel
would fail with a "FATAL: kernel too old".
Note that linux/riscv64 is currently only usable using gccgo.

Right now the process for adding in new constants, errors, or syscalls
for Linux is a pain and unreliable. The scripts are designed to be run
on the target architecture and use the header files installed on the
user's system. This makes it hard to generate files for all the
architectures or to have consistency between users. See golang/go#15282.
This CL fixes this issue by making all of the files for the 11 supported
architectures directly from source checkouts of Linux, glibc, and bluez.
This is done using Docker, the gcc cross-compilers, and qemu emulation.
Previously discussed here:
https://go-review.googlesource.com/c/37589/
A README.md file is also added to explain how all the parts of the build
system work.
In order to get the build working for all the architectures, I made
some changes to the other scripts called from mkall_linux.go:
- Files only used for generating linux code, moved to linux/
- linux/mksysnum.pl supports a specified CC compiler.
- The generated C code in mkerrors.sh changed to avoid a warning
- mkerrors.sh headers changed to fix powerpc64 bug in sys/ioctl.h
- linux/types.go no longer needs to export Ptrace structs in lowercase
Build instructions:
- Host system needs to be x86-64 Linux
- Install Docker (https://docs.docker.com/engine/installation/)
- ./mkall.sh (That's it!!!)
