When a module author retracts a version, the go command should act as
if it doesn't exist unless it's specifically requested.
When converting a revision to a version, we should ignore tags for
retracted versions. For example, if the tag v1.0.0 is retracted, and
branch B points to the same revision, we should convert B to a
pseudo-version, not v1.0.0. Similarly, if B points to a commit after
v1.0.0, we should not use v1.0.0 as the base; we can use an earlier
non-retracted tag or no base.

Currently, mhdr/methods is emitted with the same len/cap. There's no way
to distinguish between exported and non-exported methods statically.
This CL splits mhdr/methods into two parts, use "len" for number of
exported methods, and "cap" for all methods. This fixes the bug in
issue #22075, which intends to return the number of exported methods but
currently return all methods.
Note that with this encoding, we still can access either
all/exported-only/non-exported-only methods:
mhdr[:cap(mhdr)] // all methods
mhdr // exported methods
mhdr[len(mhdr):cap(mhdr)] // non-exported methods
Thank to Matthew Dempsky (@mdempsky) for suggesting this encoding.

On macOS, we can do "go build", can exec, and have the source
tree available, so we can enable more tests.
Skip ones that don't work. Most of them are due to that it
requires external linking (for now) and some tests don't work
with external linking (e.g. runtime deadlock detection). For
them, helper functions CanInternalLink/MustInternalLink are
introduced. I still want to have internal linking implemented,
but it is still a good idea to identify which tests don't work
with external linking.

Prior to this commit, the profiling code had a sleep() function that
waits and unblocks on either time.After() or a channel provided by an
http.CloseNotifier derived from a supplied http.ResponseWriter.
According to the documentation, http.CloseNotifier is deprecated:
Deprecated: the CloseNotifier interface predates Go's context package.
New code should use Request.Context instead.
This patch does just that -- sleep() now takes an *http.Request and uses
http.Request.Context() to signal when a request has been cancelled.

There is no correctness reason to zero out the w.bytes array in (w
*huffmanBitWriter).reset, since w.nbytes is correctly set to zero. The elements of
the bytes array are always written sequentially, with nbytes indicating how many
elements have been written, and are only read up to the current value of nybytes.
We have a pprof profile of a web server that compresses its request/responses, and
the zeroing in reset() is taking up 2.6% of the CPU time of the server (and could
be causing more slowdowns elsewhere due to its effects on the cache). This
overhead may be showing up especially because there are many request/responses
that are all fairly small.
I'm not sure if the zeroing of the bytes array was intended as extra protection of
data across reset uses in the same program, but no protection is needed as long as
the huffman_bit_writer code remains correct.
