ubuntu:19.04 is not supported anymore and update repos are unavailable, so
build process on Linux just fails. Latest stable ubuntu:20.04 works fine.
Also, DEBIAN_FRONTEND=noninteractive env variable has been added to prevent
unneeded questions during installation of tzdata package.

Attempting to upgrade to the Ubuntu 19.10 Docker image results in
failures due to Ubuntu/Debian removing the mips{,64}{,le} cross
compilers, so we stick with 19.04 for now.

Drop the manually defined *_XDP constants which were added to glibc.
Install python3 instead of python because glibc's confugure script now
requires at least 3.4.

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.

Also use the Ubuntu 17.10 docker image and additionally install bison
which is needed by the glibc build.
The resulting change only consists of a few additional constants.
Exclude the X86_CR3_PCID_NOFLUSH constant on 386 and amd64, though.

Update go to 1.9.2 in the Dockerfile used to generate the Linux go files.
The update also changes some zerror definitions: RLIM_INFINITY is
assigned to Rlimit.{Cur,Max} which are both uint64 on all architectures.
PR_SET_PTRACER_ANY is used with Prctl which expects an uintptr.
With the current version, an "constant -1 overflows uint64" error would
result if these constants were used directly without type conversion.

This change updates the Linux symbols to correspond to v4.13 of the
kernel and v2.26 of glibc. To get everything building correctly, newer
versions of the build tools are required. Instead of trying to get an
Ubuntu 17.10 docker image working, we just add Artful sources to
/etc/apt/sources.list to get a similar effect.
Now that the kernel UAPI is updated, FS_MAX_KEY_SIZE and fscrypt_key no
longer need to be manually declared, as they are now in the proper
kernel headers.

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!!!)
