In dynamic linking mode (e.g. when using plugins) on darwin, the
marker symbols runtime.text and runtime.etext are added to Textp
in an early stage, so when adding symbols to the symbol table we
don't need to explicitly add them. However, when splitting text
sections, the runtime.text.N marker symbols for the addtional
sections are not added to Textp. So we do need to add them
explicitly to the symbol table.
Fixes#66993.

This change fixes problems with thread-locked goroutines using
newcoro/coroswitch/etc. Currently, the coro paths do not consider
thread-locked goroutines at all and can quickly result in broken
scheduler state or lost/leaked goroutines.
One possible fix to these issues is to fall back on goroutine+channel
semantics, but that turns out to be fairly complicated to implement and
results in significant performance cliffs. More complex thread-lock
state donation tricks also result in some fairly complicated state
tracking that doesn't seem worth it given the use-cases of iter.Pull
(and even then, there will be performance cliffs).
This change implements a much simpler, but more restrictive semantics.
In particular, thread-lock state is tied to the coro at the first call
to newcoro (i.e. iter.Pull). From then on, the invariant is that if the
coro has any thread-lock state *or* a goroutine calling into coroswitch
has any thread-lock state, that the full gamut of thread-lock state must
remain the same as it was when newcoro was called (the full gamut
meaning internal and external lock counts as well as the identity of the
thread that was locked to).
This semantics allows the common cases to be always fast, but comes with
a non-orthogonality caveat. Specifically, when iter.Pull is used in
conjunction with thread-locked goroutines, complex cases (passing next
between goroutines or passing yield between goroutines) are likely to
fail. Simple cases, where any number of iter.Pull iterators are used in
a straightforward way (nested, in series, etc.) from the same
goroutine, will work and will be guaranteed to be fast regardless of
thread-lock state.
This is a compromise for the near-term and we may consider lifting the
restrictions imposed by this CL in the future.

Use Process.handle field to store pidfd, and make use of it. Only use

1. Add/use pidfdWorks, which checks that all needed pidfd-related
functionality works.
2. os.StartProcess: obtain the pidfd from the kernel, if possible, using
the functionality added by CL 520266. Note we could not modify
syscall.StartProcess to return pidfd directly because it is a public
API and its callers do not expect it, so we have to use ensurePidfd
and getPidfd.
3. (*Process).Kill: use pidfdSendSignal, if available and the pidfd is
known. Otherwise, fall back to the old implementation.
4. (*Process).Wait: use pidfdWait, if available, otherwise fall back to
using waitid/wait4. This is more complicated than expected due to
struct siginfo_t idiosyncrasy.
NOTE pidfdSendSignal and pidfdWait are used without a race workaround
(blockUntilWaitable and sigMu, added by CL 23967) because with pidfd,
PID recycle issue doesn't exist (IOW, pidfd, unlike PID, is guaranteed
to refer to one particular process) and thus the race doesn't exist
either.

HTTP requests have three separate user cancelation signals:
Transport.CancelRequest
Request.Cancel
Request.Context()
In addition, a request can be canceled due to errors.
The Transport keeps a map of all in-flight requests,
with an associated func to run if CancelRequest is
called. Confusingly, this func is *not* run if
Request.Cancel is closed or the request context expires.
The map of in-flight requests is also used to communicate
between roundTrip and readLoop. In particular, if readLoop
reads a response immediately followed by an EOF, it may
send racing signals to roundTrip: The connection has
closed, but also there is a response available.
This race is resolved by readLoop communicating through
the request map that this request has successfully
completed.
This CL refactors all of this.
In-flight requests now have a context which is canceled
when any of the above cancelation events occurs.
The map of requests to cancel funcs remains, but is
used strictly for implementing Transport.CancelRequest.
It is not used to communicate information about the
state of a request.

CL 579935 disabled usage of Alias types in the compiler, and tracks
the problem with issue #66873. The test case in #65893 passes now
with the current tip. This CL adds a test case to ensure there is no
regression once Alias types are enabled for the compiler.

callbackUpdateSystemStack contains a fast path to exit early without
update if SP is already within the g0.stack bounds.
This is not safe, as a subsequent call may have new stack bounds that
only partially overlap the old stack bounds. In this case it is possible
to see an SP that is in the old stack bounds, but very close to the
bottom of the bounds due to the partial overlap. In that case we're very
likely to "run out" of space on the system stack.
We only need to do this on extra Ms, as normal Ms have precise bounds
defined when we allocated the stack.
TSAN annotations are added to x_cgo_getstackbounds because bounds is a
pointer into the Go stack. The stack can be reused when an old thread
exits and a new thread starts, but TSAN can't see the synchronization
there. This isn't a new case, but we are now calling more often.
Fixes#62440.
