go test runs a limited number of vet checks by default.
In the standard library, we run more, both to get additional checking
for the standard library and to get experience with whether to enable
any others by default.
One that experience has shown us should not be enabled by default
is go vet -unreachable. When you are testing, it is common to want to
put an early return or a panic into code to bypass a section of code.
That often causes unreachable code. It's incredibly frustrating if the
result is an "unreachable code" error that keeps your test from completing.

Currently on darwin, when a symbol needs to be exported, we
export it both statically and dynamically. The dynamic export is
unnecessary for some symbols. Only export the necessary ones.
For special runtime C symbols (e.g. crosscall2), they used to be
exported dynamically, and we had a special case for pclntab to
not include those symbols (otherwise, when the dynamic linker
dedup them, the pclntab entries end up pointing out of the
module's address space). This CL changes it to not export those
symbols, and remove the special case.

Add note about using per-use seeds.
Delete "collision-resistant but" in:
> The hash functions are collision-resistant but not cryptographically secure.
"Collision-resistant" has a precise cryptographic meaning that is
incompatible with "not cryptographically secure".
All that is really meant by it here here is "it's a good hash function",
which should be established already.
Also delete:
> The hash value of a given byte sequence is consistent within a
> single process, but will be different in different processes.
This was added for its final clause in response to #37040,
but "The hash value of a given byte sequence" is by design not a
concept in this package. Only "... of a given seed and byte sequence".
And seeds cannot be shared between processes, so again by design
you can't even set up the appropriate first half of the sentence
to say the second half.

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.

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.
