There was a bug in TestResumption: the first ExpiredSessionTicket was
inserting a ticket far in the future, so the second ExpiredSessionTicket
wasn't actually supposed to fail. However, there was a bug in
checkForResumption->sendSessionTicket, too: if a session was not resumed
because it was too old, its createdAt was still persisted in the next
ticket. The two bugs used to cancel each other out.

Ever since session ticket key rotation was introduced in CL 9072, we've
been including a prefix in every ticket to identify what key it's
encrypted with. It's a small privacy gain, but the cost of trial
decryptions is also small, especially since the first key is probably
the most frequently used.
Also reissue tickets on every resumption so that the next connection
can't be linked to all the previous ones. Again the privacy gain is
small but the performance cost is small and it comes with a reduction in
complexity.

The existing implementation allocates a new 4KB buffer each time it opens flate-encoded file in a zip archive. This commit allows the flate reader to reuse the buffer on call Reset instead of allocating a new one.
It is noticeable when a zip archive contains a huge amount of files, e.g. zip archive has 50_000 files, for each file 4KB buffer is allocated, so it is 200MB memory allocations. If files are read sequentially only one buffer is needed.

RSA encryption and verification performs an exponentiation by a value
usually just a few bits long. The current strategy with table
precomputation is not efficient.
Add an ExpShort bigmod method, and use it in RSA public key operations.
After this, almost all CPU time in encryption/verification is spent
preparing the constants for the modulus, because PublicKey doesn't have
a Precompute function.
This speeds up signing a bit too, because it performs a verification to
protect against faults.

CL 497075 refactored NewFile to unconditionally dereference the file
returned by newFile. However, newFile can return nil if passed a
negative FD, which now causes a crash.
Resolve this by moving the invalid check earlier in NewFile, which also
lets us avoid a useless fcntl syscall on a negative FD.
Since we convert to int to check sign, adjust newFile to take an int
rather than uintptr, which cleans up a lot of conversions.

Use io.Copy¹ that matches the comment more closely, avoids the
possibility of needing a bigger array, and is slightly shorter.
Its downside is that it takes two w.Write calls instead of one.
¹ Admittedly, it was temping to use io.CopyBuffer since the 'data'
byte slice becomes a viable buffer after its contents are written.
I resisted that temptation for two reasons.
One, it would need the io.Reader returned by dec.Buffered() (currently
a *bytes.Reader) to not implement the io.WriterTo interface for any
chance of making a positive difference. This seems not very likely.
Two, to avoid burdening anyone with determining that io.CopyBuffer
won't panic without 'if len(data) == 0 && data != nil { data = nil }'
because json.Marshal never returns an empty but non-nil byte slice.

The failure in build_pgo_auto_multi.txt is more interesting. If the
first argument to stdout starts with `-` the script engine expects it to
be a flag to grep, and thus doesn't regexp-escape `\` in the expansion
of `${/}`.
The script engine doesn't _require_ that these are flags to grep, so it
is still possible to use them for matching, but this ideally will change
in the future, so change all patterns to avoid starting with `-`.

In theory by allocating new objects every time, the benchmark is
including the performance of allocating new pinner bits for a span. In
practice however, most of the time each span already does have pinner
bits allocated (it's still a rare operation).
We can get a better sense of the raw cost of pinning an object (minus
pinner bits allocation) by moving the object allocation out of the inner
loop.

Name constraints are checked during path building. When a new
certificate is considered for inclusion in a chain we check if it has
name constraints, and if it does, check that they apply to the certs
already in the chain, discarding it if the current chain violates any
of the constraints the candidate introduces.
This check was not acting as intended in two ways. The first was that
we only checked that the constraints on the candidate certificate
applied to the leaf certificate, and not the rest of the certiifcates in
the chain. This was the intended behavior pre-1.19, but in 1.19 we
intended for the constraints to be applied to the entire chain (although
obviously they were not).
The second was that we checked that the candidates constraints applied
to the candidate itself. This is not conformant with RFC 5280, which
says that during path building the constraint should only be applied to
the certificates which follow the certificate which introduces the
constraint (e.g. in the chain A -> B -> C, if certificate Bcontains a
name constraint, the constraint should only apply to certificate C).
The intended behavior introduced in 1.19 was mainly intended to reject
dubious chains which the WebPKI disallows, and are relatively rare, but
don't have significant security impact. Since the constraints were
properly applied to the leaf certificate, there should be no real impact
to the majority of users.

This test is fundamentally flaky because of a mismatch between how
internal idle time is calculated and how the test expects it to be
calculated. It's unclear how to resolve this mismatch, given that it's
perfectly valid for a goroutine to remain asleep while background
goroutines (e.g. the scavenger) run. In practice, we might be able to
set some generous lower-bound, but until we can confirm that on the
affected platforms, skip the test as flaky unconditionally.
For #60276.

setPGOProfilePath sets Package.Internal.PGOProfile very late in package
loading (because it may split/copy packages). Build info was computed
long before this, causing PGO packages to miss -pgo from their build
settings.
Adjust BuildInfo to be stored as *debug.BuildInfo rather than eagerly
converting to a string. This enables setPGOProfilePath to update the
BuildInfo at the same point that it sets PGOProfile.
