This CL breaks Go 1 API compatibility but it doesn't matter because
previous ListenUnixgram doesn't work in any use cases, oops.
The public API change is:
-pkg net, func ListenUnixgram(string, *UnixAddr) (*UDPConn, error)
+pkg net, func ListenUnixgram(string, *UnixAddr) (*UnixConn, error)
Fixes#3875.

Ignore signals during "go run" and wait for running child
process to exit. Stop executing further tests during "go test",
wait for running tests to exit and report error exit code.

I just committed a patch to gccgo that notices that float was
never defined, causing an additional unmatched error message.
Rename the type to avoid that message.

I've been writing some code which involves syncing files (like
rsync) and it became apparent that under Linux I could read
modification times (os.Lstat) with nanosecond precision but
only write them with microsecond precision. This difference
in precision is rather annoying when trying to discover
whether files need syncing or not!
I've patched syscall and os to increases the accuracy of of
os.Chtimes for Linux and Windows. This involved exposing the
utimensat system call under Linux and a bit of extra code
under Windows. I decided not to expose the "at" bit of the
system call as it is impossible to replicate under Windows, so
the patch adds syscall.Utimens() to all architectures along
with a ImplementsUtimens flag.
If the utimensat syscall isn't available (utimensat was added
to Linux in 2.6.22, Released, 8 July 2007) then it silently
falls back to the microsecond accuracy version it uses now.
The improved accuracy for Windows should be good for all
versions of Windows.
Unfortunately Darwin doesn't seem to have a utimensat system
call that I could find so I couldn't implement it there. The
BSDs do, but since they share their syscall implementation
with Darwin I couldn't figure out how to define a syscall for
*BSD and not Darwin. I've left this as a TODO in the code.
In the process I implemented the missing methods for Timespec
under Windows which I needed which just happened to round out
the Timespec API for all platforms!

Fixes#4467.
The syslog tests can fail if the timeout fires before the data arrives at the mock server. Moving the timeout onto the goroutine that is calling ReadFrom() and always processing the data returned before handling the error should improve the reliability of the test.

This is language change. It is a backward-compatible
change but for code that relies on a run-time panic
when calling delete on a nil map (unlikely).

Change suggested by iant. The compiler generates
special code for a/b when a is -0x80...0 and b = -1.
A single instruction can cover the case where b is -1,
so only one comparison is needed.

Also, implement a global OPTIONS * handler, like Apache.
Permit sending "*" requests to handlers, but not path-based
(ServeMux) handlers. That means people can go out of their
way to support SSDP or SIP or whatever, but most users will be
unaffected.
