156c5a2da4 unix: use struct pt_regs for PtraceRegs on mips
On mips, "struct user" bears no relation to the actual structure used by
PTRACE_GETREGS. The real structure is "struct pt_regs" which is declared
in asm/ptrace.h

Fixes golang/go#20338.

8c0a5eacba unix: add support for Linux filesystem encryption
This CL adds in the necessary types and constants to support Linux
filesystem encryption. This includes the structs for the keys and
polices as well as the constants for key size and encryption algorithms.

This code also reduces the scope of some of the regexes in mkerrors.sh.
This is to reduce the number of unrelated constants added in with this
change.

Note that due to a bug in the Linux uapi headers, not all of the
necessary constants and structures are declared in linux/fs.h despite
being part of the kernel ABI. This means that some constants and types
had to be manually added in.

The bug has been patched (https://patchwork.kernel.org/patch/9662723),
and the manual additions can be removed when the patch is merged into
the mainline kernel.

ea9bcade75 unix: generate all Linux go files from source
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!!!)
