d03611f628 allow copy of struct containing unexported fields
An experiment: allow structs to be copied even if they
contain unexported fields.  This gives packages the
ability to return opaque values in their APIs, like reflect
does for reflect.Value but without the kludgy hacks reflect
resorts to.

In general, we trust programmers not to do silly things
like *x = *y on a package's struct pointers, just as we trust
programmers not to do unicode.Letter = unicode.Digit,
but packages that want a harder guarantee can introduce
an extra level of indirection, like in the changes to os.File
in this CL or by using an interface type.

All in one CL so that it can be rolled back more easily if
we decide this is a bad idea.

Originally discussed in March 2011.

0acd879c26 syscall: take over env implementation
The environment is needed by package time, which
we want not to depend on os (so that os can use
time.Time), so push down into syscall.

Delete syscall.Sleep, now unnecessary.

The package os environment API is preserved;
it is only the implementation that is moving to syscall.

Delete os.Envs, which was undocumented,
uninitialized on Windows and Plan 9, and
not maintained by Setenv and Clearenv.
Code can call os.Environ instead.

631a575fd9 html: store the current insertion mode in the parser
Currently, the state transition functions in the HTML parser
return the next insertion mode and whether the token is consumed.
This works well except for when one insertion mode needs to use
the rules for another insertion mode. Then the useTheRulesFor
function needs to patch things up. This requires comparing functions
for equality, which is going to stop working.

Adding a field to the parser structure to store the current
insertion mode eliminates the need for useTheRulesFor;
one insertion mode function can now just call the other
directly. The insertion mode will be changed only if it needs to be.

This CL is an alternative to CL 5372078.
