If a wasmexport function is called from the host before

spec:
https://pages.nist.gov/ACVP/draft-vassilev-acvp-drbg.html#section-7.2
The HMAC DRBG algorithm in our fips module is a minimal implementation
tailored for use for generating ECDSA nonces and so lives in
crypto/internal/fips140/ecdsa.
In order to be testable by crypto/internal/fips140test this changeset
exports a ecdsa.TestingOnlyNewDrbg() constructor to support the ACVP use-case.
All FIPS-compatible SHA2 and SHA3 digests are tested.
The ACVP capability registration is customized to match the limited
capabilities of our ecdsa-focused impl. Most notably:
* reseedImplemented is false - we expect this impl to be invoked
only once or twice per instantiation and do not support explicit
reseeding.
* predResistanceEnabled is false - this requires reseeding.
* Per mode:
* derFuncEnabled is always false - this is only used by ctrDRBG.
* additionalInputLen is 0 for all modes - this is only used with
preResistanceEnabled.
The other capability values are chosen based on Table 4:

A few non-test updates are also required for the
crypto/internal/fips140/mlkem package:
* For keyGen tests a new ExpandedBytes768() function is added that
converts a DecapsualtionKey768 struct into the expanded NIST
serialization. The existing Bytes() function returns the
key's seed, while ACVP testing requires the more cumbersome format.
* For decap tests a new TestingOnlyNewDecapsulationKey768()
constructor is added to produce a DecapsulationKey768 struct from the
expanded FIPS 203 serialization provided by the ACVP test vector. The
pre-existing NewDecapsulationKey768() function expects a seed as
input.
The generate1024.go helper is updated to translate the above changes to
the generated mlkem1024.go implementation.
Both of these new functions are exclusively for ACVP usage and so not
present in the public mlkem API. End users should always prefer to work
with seeds.

runtime: hold traceAcquire across casgstatus in injectglist
Currently injectglist emits all the trace events before actually calling
casgstatus on each goroutine. This is a problem, since tracing can
observe an inconsistent state (gstatus does not match tracer's 'emitted
an event' state).
This change fixes the problem by having injectglist do what every other
scheduler function does, and that's wrap each call to casgstatus in
traceAcquire/traceRelease.
Fixes #70883.

The easiest fix is to make the tools compatible with this GODEBUG

I made the wrappers select different sections of the hash, but
none of the call sites really care.

Allow a gocacheprog to not respond to close. The intention of the code

then block forever waiting for a response. With this change, we close
all response channels for pending responses if there's an error reading
from the cacheprog's stdout while we're closing. The receives from the
response channels would then proceed (but now have to handle a nil
value). Then the send operation would return and the (*ProgCache).Close

context: use "canceled" in docs to refer to timed-out contexts
In documentation, we've usually but not always referred to a
context with a closed Done channel as "done" rather than
"canceled", to avoid ambiguity between a context canceled
by calling a CancelFunc and one past its deadline.
This actually adds ambiguity, however, since it's common to
see references to a "canceled context" that are intended to
cover contexts past their deadline. If you see "function F
returns if its context is canceled", you can reasonably
assume that F will return if its context passes its
deadline, unless something says otherwise.
Update the context package docs to explicitly state that
a context is canceled when its deadline passes. Drop references
to contexts becoming "done" and just use "canceled" throughout.

The GNU linker interprets @file as "read command-line options from file".
Thus, we forbid values starting with @ on linker flags. However, this
causes a problem when targeting Darwin. @executable_path, @loader_path, and
@rpath are special values used in Mach-O to change the library search path
and can be used in conjunction with the -install_name and -rpath linker
flags. Since the GNU linker does not support Mach-O, targeting Darwin
implies not using the GNU linker. Therefore, we allow @ in the linker flags
if and only if cfg.Goos == "darwin".

cmd/link, runtime: apply a delta to RODATA->DATA relocations
On AIX, an R_ADDR relocation from an RODATA symbol to a DATA
symbol does not work, as the dynamic loader can change the address
of the data section, and it is not possible to apply a dynamic
relocation to RODATA. In order to get the correct address, we
apply the delta between unrelocated and relocated data section
addresses at run time. The linker saves both the unrelocated and
the relocated addresses, so we can compute the delta.
This is possible because RODATA symbols are generated by the
compiler and so we have full control of. On AIX, the only case
is the on-demand GC pointer masks from the type descriptors, for
very large types.
Perhaps there is a better way.
