detect loop conditions written in reversed order respect to the
idiomatic way (eg: for i:=0; len(n)>i; i++).

RFC 7230 is clear about headers with a space before the colon, like
X-Answer : 42
being invalid, but we've been accepting and normalizing them for compatibility
purposes since CL 5690059 in 2012.
On the client side, this is harmless and indeed most browsers behave the same
to this day. On the server side, this becomes a security issue when the
behavior doesn't match that of a reverse proxy sitting in front of the server.
For example, if a WAF accepts them without normalizing them, it might be
possible to bypass its filters, because the Go server would interpret the
header differently. Worse, if the reverse proxy coalesces requests onto a
single HTTP/1.1 connection to a Go server, the understanding of the request
boundaries can get out of sync between them, allowing an attacker to tack an
arbitrary method and path onto a request by other clients, including
authentication headers unknown to the attacker.
This was recently presented at multiple security conferences:
https://portswigger.net/blog/http-desync-attacks-request-smuggling-reborn
net/http servers already reject header keys with invalid characters.
Simply stop normalizing extra spaces in net/textproto, let it return them
unchanged like it does for other invalid headers, and let net/http enforce
RFC 7230, which is HTTP specific. This loses us normalization on the client
side, but there's no right answer on the client side anyway, and hiding the
issue sounds worse than letting the application decide.

If the parent context passed to WithCancel or WithTimeout
is a known context implementation (one created by this package),
we attach the child to the parent by editing data structures directly;
otherwise, for unknown parent implementations, we make a
goroutine that watches for the parent to finish and propagates
the cancellation.
A common problem with this scheme, before this CL, is that
users who write custom context implementations to manage
their value sets cause WithCancel/WithTimeout to start
goroutines that would have not been started before.
This CL changes the way we map a parent context back to the
underlying data structure. Instead of walking up through
known context implementations to reach the *cancelCtx,
we look up parent.Value(&cancelCtxKey) to return the
innermost *cancelCtx, which we use if it matches parent.Done().
This way, a custom context implementation wrapping a
*cancelCtx but not changing Done-ness (and not refusing
to return wrapped keys) will not require a goroutine anymore
in WithCancel/WithTimeout.

There are currently two edges in the lock cycle graph caused by
scavenge.lock: with sched.lock and mheap_.lock. These edges appear
because of the call to ready() and stack growths respectively.
Furthermore, there's already an invariant in the code wherein
mheap_.lock must be acquired before scavenge.lock, hence the cycle.
The fix to this is to bring scavenge.lock higher in the lock cycle
graph, such that sched.lock and mheap_.lock are only acquired once
scavenge.lock is already held.
To faciliate this change, we move scavenger waking outside of
gcSetTriggerRatio such that it doesn't have to happen with the heap
locked. Furthermore, we check scavenge generation numbers with the heap
locked by using gopark instead of goparkunlock, and specify a function
which aborts the park should there be any skew in generation count.
Fixes#34047.

The macOS filesystem seems to have gotten significantly flakier as of
macOS 10.14, so this causes frequently flakes in the 10.14 builders.
We have no reason to believe that it will be fixed any time soon, so
rather than trying to detect the specific macOS version, we'll apply
the same workarounds that we use on Windows: classifying (and
retrying) the errors known to indicate flakiness and relaxing the
success criteria for renameio.TestConcurrentReadsAndWrites.
Fixes#33041
