Add ErrnoName and SignalName to get errno and signal name strings from
syscall.Errno and syscall.Signal values, respectively.
This repurposes the errors and signals vars (because they are not used
within x/sys/unix currently) and turns them into slices of struct,
containing errno/signal number, name and description. ErrnoName and
SignalName can then be trivially implemented using sort.Search.
Renaming errors to errorList additionaly allows to avoid package aliases
for the errors package.

statx(2) allows to get enhanced file status information (not currently
available through the existing stat syscalls), lightweight stat,
heavyweight stat. The Statx_t type used by Statx has consistent field
sizes on all arches (with year-2038-capable timestamps) and is closer to
the BSD implementation of Stat_t.
See http://man7.org/linux/man-pages/man2/statx.2.html for details. The
syscall was added in Linux kernel 4.11.
See https://github.com/tklauser/statx for an example of how this
function and types can be used to report stat(1)-like file status
information.

This CL adds support for the ADD_KEY, REQUESET_KEY, and KEYCTL syscalls.
These syscalls allow access to the kernel keyring facilities. In C code,
these syscalls are wrapped by the libkeyutils package. See:
http://man7.org/linux/man-pages/man7/keyutils.7.html
The ADD_KEY and REQUEST_KEY calls are fairly straightforward, but the
KEYCTL syscall is a multiplexor for a number of key management
functions. See:
http://man7.org/linux/man-pages/man3/keyctl.3.html
The Go bindings for the KEYCTL functions attempt to replicate what
libkeyutils does. This is done via generated helper functions.

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.

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!!!)

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.
