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.

Fixes #3790
I hope forever, but I doubt that very much.

5822e7848a runtime: make SetFinalizer(x, f) accept any f for which f(x) is valid
Originally the requirement was f(x) where f's argument is
exactly x's type.

CL 11858043 relaxed the requirement in a non-standard
way: f's argument must be exactly x's type or interface{}.

If we're going to relax the requirement, it should be done
in a way consistent with the rest of Go. This CL allows f's
argument to have any type for which x is assignable;
that's the same requirement the compiler would impose
if compiling f(x) directly.

Fixes #5368.
