On Linux, we can extract a list of all the processes on the system by
calling readdir() against /proc. On BSD-like systems, this information
needs to be extracted from sysctl in the form of kinfo_proc structures.
This change adds bindings for this structure and adds a method for
reading an array of these structures from sysctl.

There is some inconsistent use of tabs and spaces in the //sys and

consistently.
Also change the regexp in mksyscall*.go to only accept tabs going

The raw syscall returned the two pipes whereas the libc call
takes a pointer to a location to write the two pipes.
When we switched over from raw syscalls to libc calls, this
change in behavior was missed.

CL 250437 removed the zsysnum_darwin_*.go files containing the SYS_*
contants for macOS. This was done assuming that users should migrate
away from direct syscalls to libSystem wrappers. Let's not force users
of this package on when they want to do that and re-add the
zsysnum_darwin_*.go files and mark the consts as deprecated.
We can still remove these once macOS actively prevents use of direct
syscalls.

CL 250437 removed all SYS_* consts on darwin as direct syscalls are no

While the other BSDs use __sysctl as the name, Darwin now uses sysctl,
without the leading underscores, and considers __sysctl to be "private".
Using __sysctl leads to App Store rejections, and Go's syscall package
already uses the proper syscall. So this commit changes Darwin's syscall
to use it too here, while reverting a recent commit that removed it all
together on arm and arm64.
This reverts CL 194097.

It's only when dest is set to NULL that the OS X implementations of
getxattr() and listxattr() return the current sizes of the named
attributes. An empty byte array is not sufficient. To maintain the same
behaviour as the linux implementation, we wrap around the system calls
and pass in NULL when dest is empty.
The parameters for the OS X implementation of setxattr() vary slightly
compared to the linux system call, specifically the 'position'
parameter:
linux:
int setxattr(
const char *path,
const char *name,
const void *value,
size_t size,
int flags
);
darwin:
int setxattr(
const char *path,
const char *name,
void *value,
size_t size,
u_int32_t position,
int options
);
'position' specifies the offset within the extended attribute. In the
current implementation, only the resource fork extended attribute makes
use of this argument. For all others, position is reserved. We simply
default to setting it to zero. If that's needed by the package user, a
function with a different name needs to be implemented instead.
Similarly for removexattr(), we wrap around and explicitly zero out the
options provided. We do so for interoperability with the linux variant.
If options are needed by the package user, a function with a different
name needs to be implemented instead.

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.
