e5da18df52 os/exec: constrain thread usage in leaked descriptor test on illumos
On illumos systems, libc can under some conditions make use of files
from /proc.  In the case of this test, the creation of new threads was
(in the target thread) causing libc to open and close
"/proc/self/lwp/5/lwpname" to set the thread name, which raced with the
leaking descriptor check (see detailed analysis in #42431).

This change requests that the Go runtime use less threads in the child
process used to check for leaked descriptors, without just disabling the
test.  After a thousand repeated trials, the test no longer fails on
illumos.

Fixes #42431.

Many of the standard library changes that were added before CL 272871
ended up in the "Core library" section. That section is meant for
major changes like new packages, and most of these aren't.

Consolidate all changes in the "Minor changes to the library" section

each package, along with the remaining TODOs. Add a TODO to read them
over at the end and factor out items that are worth highlighting.

Apply minor other fixups to improve consistency.

CL 34641 changed the Go runtime to assume GOARM=7 support on Android.
This change completes that by assuming GOARM=7 in the toolchain, fixing

There is already code in cmd/dist to force GOARM to 7 on GOOS=android. However,
dist is most likely run with GOOS != android.

df68e01b68 runtime: check channel's elemsize before calling race detector
When c.elemsize==0 we call raceacquire() and racerelease()
as opposed to calling racereleaseacquire()

The reason for this change is that, when elemsize==0, we don't
allocate a full buffer for the channel.  Instead of individual
buffer entries, the race detector uses the c.buf as the only
buffer entry.  This simplification prevents us following the
memory model's happens-before rules implemented in racereleaseacquire().
So, instead of calling racereleaseacquire(), we accumulate
happens-before information in the synchronization object associated
with c.buf.

The functionality in this change is implemented in a new function
called racenotify()

e8de596f04 runtime: use inlined function name for traceback elision
Currently, gentraceback decides which frames to print or elide when
unwinding inlined frames using only the name of the outermost
function. If the outermost function should be elided, then inlined
functions will also be elided, even if they shouldn't be.

This happens in practice in at least one situation. As of CL 258938,
exported Go functions (and functions they call) can now be inlined
into the generated _cgoexp_HASH_FN function. The runtime elides
_cgoexp_HASH_FN from tracebacks because it doesn't contain a ".".
Because of this bug, it also elides anything that was inlined into it.

This CL fixes this by synthesizing a funcInfo for the inlined
functions to pass to showframe.

Fixes #42754.

This change adjusts usleep2HighRes so it does not crash when TLS is
not configured. When g is not available, usleep2HighRes just calls
usleep2 instead.

f7342596da syscall: add DLLError.Unwrap function
Because we're expecting for future functions to be unavailable, we
should add an Unwrap() function to the DLLError struct, so that people
can test for this situation easily via:

    if errors.Is(err, syscall.ERROR_PROC_NOT_FOUND) { ... }

DLLError already was wrapping the underlying Errno error, but never got

f93ef07b11 cmd/go/internal/modload: remove the Reqs function
The Reqs function returns an mvs.Reqs implemention for the global
build list. The API that it presents assumes that the build list is
globally consistent (problematic for #40775) and readily available
(problematic for #36460).

Fortunately, it is no longer used outside of the modload package.
We can instead use individual instances of the unexported mvsReqs
struct, making the dependency on the global build list more explicit.

Instead, remove the ListModules call and fix the test that
