0b25ba9ced misc/emacs: allow godef to work in coverage buffers
Jumps to the same file will use the original buffer, not the
coverage buffer. Making it work for the coverage buffer isn't
worth the trouble, especially because it would break as soon as
you jump to a different file and back.

Use error instead of message so it actually terminates

f0fef32383 cmd/go: fix at least some instances of double compilation
When the packages the tested package depends on don't build,

this fixes the one listed in the issue.

5d5defc77f net: rearrange the call order of runtime-integrated network pollster and syscall functions
This CL rearranges the call order for raw networking primitives like
the following;

- For dialers that open active connections, pollDesc.Init will be
  called before syscall.Connect.

- For stream listeners that open passive stream connections,
  pollDesc.Init will be called just after syscall.Listen.

- For datagram listeners that open datagram connections,
  pollDesc.Init will be called just after syscall.Bind.

This is in preparation for runtime-integrated network pollster for BSD
variants.

a454d2fd2e time: expand acceptance of time zones when parsing
I tried to make it absolutely correct but there are too many
conflicting definitions for the official list of time zones.
Since when we're parsing we know when to expect
a time zone and we know what they look like if not exactly
what the definitive set is, we compromise. We accept any
three-character sequence of upper case letters, possibly
followed by a capital T (all four-letter zones end in T).

There is one crazy special case (ChST) and the possibility
of a signed hour offset for GMT.
