The previous implementation spawned an extra goroutine to handle
rechecking resolv.conf for changes.
This change eliminates the extra goroutine, and has rechecking
done as part of a lookup. A side effect of this change is that the
first lookup after a resolv.conf change will now succeed, whereas
previously it would have failed. It also fixes rechecking logic to
ignore resolv.conf parsing errors as it should.

All slice types which have elements of kind reflect.Uint8 are marshalled
into base64 for compactness. When decoding such data into a custom type
based on []byte the decoder checked the slice kind instead of the slice
element kind, so no appropriate decoder was found.
Fixed by letting the decoder check slice element kind like the encoder.
This guarantees that already encoded data can still be successfully
decoded.
Fixes#8962.

Preallocating them in reflect means that
(1) if you say _ = PtrTo(ArrayOf(1000000000, reflect.TypeOf(byte(0)))), you just allocated 1GB of data
(2) if you say it again, that's *another* GB of data.
The only use of t.zero in the runtime is for map elements.
Delay the allocation until the creation of a map with that element type,
and share the zeros.
The one downside of the shared zero is that it's not garbage collected,
but it's also never written, so the OS should be able to handle it fairly
efficiently.

According to MSDN RegQueryValueEx page:
If the data has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, the
string may not have been stored with the proper terminating null
characters. Therefore, even if the function returns ERROR_SUCCESS, the
application should ensure that the string is properly terminated before
using it; otherwise, it may overwrite a buffer. (Note that REG_MULTI_SZ
strings should have two terminating null characters.)

This reduces the depth of the inlining at a particular call site.
The inliner introduces many temporary variables, and the compiler can do
a better job with fewer. Being verbose in the bodies of these helper functions
seems like a reasonable tradeoff: the uses are still just as readable, and
they run faster in some important cases.

The Transport's writer to the remote server is wrapped in a
bufio.Writer to suppress many small writes while writing headers and
trailers. However, when writing the request body, the buffering may get
in the way if the request body is arriving slowly.
Because the io.Copy from the Request.Body to the writer is already
buffered, the outer bufio.Writer is unnecessary and prevents small
Request.Body.Reads from going to the server right away. (and the
io.Reader contract does say to return when you've got something,
instead of blocking waiting for more). After the body is finished, the
Transport's bufio.Writer is still used for any trailers following.
A previous attempted fix for this made the chunk writer always flush
if the underlying type was a bufio.Writer, but that is not quite
correct. This CL instead makes it opt-in by using a private sentinel
type (wrapping a *bufio.Writer) to the chunk writer that requests
Flushes after each chunk body (the chunk header & chunk body are still
buffered together into one write).
