Avoid getting out of synch when a function, such as main.init,
has no associated line number information.  Without this the
function before main.init can skip the PC all the way to the
next function, which will cause the next function's line table
to be associated with main.init, and leave subsequent
functions with the wrong line numbers.

On Mac X 10.6 /etc/resolv.conf is changed dynamically,
and may not exist at all when all network connections
are turned off, thus any lookup, even for "localhost"
would fail with "error reading DNS config: open
/etc/resolv.conf: no such file or directory". This
change avoids the error by trying to lookup addresses
in /etc/hosts before loading DNS config.

This CL makes reflect require that values be assignable to the target type
in exactly the same places where that is the rule in Go.  It also adds
the Implements and AssignableTo methods so that callers can check
the types themselves so as to avoid a panic.

Before this CL, reflect required strict type identity.

This CL expands Call to accept and correctly marshal arbitrary
argument lists for variadic functions; it introduces CallSlice for use
in the case where the slice for the variadic argument is already known.

Fixes #327.

This CL makes it possible to resolve DNS names on OS X
without offending the Application-Level Firewall.

It also means that cross-compiling from one operating
system to another is no longer possible when using
package net, because cgo needs to be able to sniff around
the local C libraries.  We could special-case this one use
and check in generated files, but it seems more trouble
than it's worth.  Cross compiling is dead anyway.

It is still possible to use either GOARCH=amd64 or GOARCH=386
on typical Linux and OS X x86 systems.

It is also still possible to build GOOS=linux GOARCH=arm on
any system, because arm is for now excluded from this change
(there is no cgo for arm yet).

not just packages.

"goinstall foo.googlecode.com/hg/bar" will build the command named
"bar" and install it to GOBIN. "goinstall ." will use the name of the
