When deciding whether to forward cookies or sensitive headers
across a redirect, do not attempt to interpret an IPv6 address
as a domain name.
Avoids a case where a maliciously-crafted redirect to an
IPv6 address with a scoped addressing zone could be
misinterpreted as a within-domain redirect. For example,
we could interpret "::1%.www.example.com" as a subdomain
of "www.example.com".
Thanks to Juho Nurminen of Mattermost for reporting this issue.

alreadyInChain assumes all keys fit a interface which contains the
Equal method (which they do), but this ignores that certificates may
have a nil key when PublicKeyAlgorithm is UnknownPublicKeyAlgorithm. In
this case alreadyInChain panics.
Check that the key is non-nil as part of considerCandidate (we are never
going to build a chain containing UnknownPublicKeyAlgorithm anyway).

This CL changes the behavior of os.Lstat to stop setting the
os.ModeSymlink type mode bit for mount points on Windows. As a result,
filepath.EvalSymlinks no longer evaluates mount points, which was the
cause of many inconsistencies and bugs.
Additionally, os.Lstat starts setting the os.ModeIrregular type mode bit
for all reparse tags on Windows, except for those that are explicitly
supported by the os package, which, since this CL, doesn't include mount
points. This helps to identify files that need special handling outside
of the os package.
This behavior is controlled by the `winsymlink` GODEBUG setting.
For Go 1.23, it defaults to `winsymlink=1`.
Previous versions default to `winsymlink=0`.

The problem was caused by faulty handling of unSSA-able
operations on zero-sized data in expand calls, but there
is no point to operations on zero-sized data. This CL adds
a simplify step to the first place in SSA where all values
are processed and replaces anything producing a 0-sized
struct/array with the corresponding Struct/Array Make0
operation (of the appropriate type).
I attempted not generating them in ssagen, but that was a
larger change, and also had bugs. This is simple and obvious.
The only question is whether it would be worthwhile to do it
earlier (in numberlines or phielem).

Currently we use pointer equality on types when deciding whether we can
reuse a stack slot. That's too strict, as we don't guarantee pointer
equality for the same type. In particular, it can vary based on whether
PtrTo has been called in the frontend or not.
Instead, use the type's LinkString, which is guaranteed to both be
unique for a type, and to not vary given two different type structures
describing the same type.

Continuing conversion from C to Go, introduce type timers
encapsulating all timer heap state, with methods for operations.
This should at least be easier to think about, instead of having
these fields strewn through the P struct. It should also be easier
to test.
I am skeptical about the pair of atomic int64 deadlines:
I think there are missed wakeups lurking.
Having the code in an abstracted API should make it easier
to reason through and fix if needed.
[This is one CL in a refactoring stack making very small changes
in each step, so that any subtle bugs that we miss can be more
easily pinpointed to a small change.]

The itab we're initializing again, just to figure out which method
is missing, might be stored in read-only memory.
This can only happen in certain weird generics situations, so it is
pretty rare, but it causes a runtime crash when it does happen.
