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.

- mkerrors.sh: Included several termios-related constants that were
missing. Also included definitions of tty-related ioctl numbers for
linux.
- zerrors_linux_*: the files have been generated using
"./mkerrors.sh". After their automatic generation the files have
been manually edited to remove changes that were not due to this
patch.

Clang is much more common now so use the OS cc instead of forcing gcc

The existing code has no way to manipulate termios or winsize structures
on solaris. This change adds IoctlGetXXX and IoctlSetXXX functions for
int, termios, termio, and winsize. The embedded awk script in
mkerrors.sh has additional patterns to generate the needed ioctl
constants for these calls.

Various syscalls offered by x/sys/unix on Linux are not available on
Solaris and should be, such as Mkfifo, Getwd(), Futimes() and others.
In particular, all of the *at() variants of existing functions were
added where appropriate.
Getgroups() was fixed to use the correct value for its sanity check on
the maximum number of groups.
Utimesnano() was updated to use the native Solaris utimensat function
for setting nanosecond-precision time.
Utimes() was updated to have the same error semantics and checking as
other platforms.
Getgroups(), anysocktoaddr(), and Recvmsg() were fixed to check the
return value before assuming syscall failure instead of relying solely
on errno being set.
mksyscall_solaris.pl needed some updates to better match the output of
the one found in syscall.
mkerrors.sh needed some updates to work out of the box on Solaris,
matching those recently done to the one in syscall.
The signatures (names) of some function parameters were changed to be
consistent with other platforms for the sake of documentation.

I did this on OS X 10.10.5 (14F27) using the 10.10 SDK included in Xcode
6.4 (6E35b). This required removing a C include from mkerrors.sh, since
it doesn't exist on either of my two systems.
I spot checked the syscall number changes against this definitive list,
which is for approximately my kernel version:
http://www.opensource.apple.com/source/xnu/xnu-2782.20.48/bsd/kern/syscalls.master
Everything I examined checked out, including the removed syscalls being
marked as "old" or being described in comments as no longer existing.
There is one exception to the output being cleanly autogenerated: I have
manually renamed SYS_SYSCTL back to SYS___SYSCTL, the name used
previously and still used by syscall_bsd.go. Because it would distract
from this CL, I will fix this in an upcoming CL.

Add wrappers that provide Linux-y behavior around the FreeBSD extattr(2)
functions. This allows certain packages, like the fuse package to run

If we use a local type, it won't compare properly with errors from
the rest of the standard library. Errors are the one type from syscall
that propagates through the system, so it's important to have only
one type for them.
Ditto for syscall.Signal.

Darwin/amd64 now builds. No others tested yet.
mkall.sh also runs correctly. The updates, which are
substantial, are not yet applied to avoid unnecessary churn.
Restore mkerrors.sh, which is needed in the unix directory.
