…(#42470)

* Revert "Make Console.ReadKey() distinguish between CR and LF inputs (#37491)"

This reverts commit a62bfcb.

* Account for terminals that have ICRNL disabled

* Add manual tests that validates the current \n ReadKey() behaviour on Unix

…42609)

- Style analyzer fixes
- ARM64 port

* Fix a few Socket.SendFile issues

- The string argument in the single-argument overload should be nullable.
- All overloads on Windows should allow a null file path, but they've been throwing an exception
- On Linux, data was silently truncated when sending a file larger than int.MaxValue with BeginSendFile.

* Address PR feedback

The singilefilehost needs to follow the libraries build in terms of how
it links to OpenSSL: if it's a non-portable build, the singlefilehost
needs to link to OpenSSL via linker arguments.

The installer also needs to have FEATURE_DISTRO_AGNOSTIC_SSL defined
just like it is defined for the libraries build.

Fixes: #41768

Fixes:
    stress client double read of content fixed
    fixed stress client hangs at start and stop
    leveraged HttpVersionPolicy
    increased pipeline timeout since we doubled the runs
    fixed base docker images to avoid missing IO.Pipelines Kestrel exception.

Re-hauled tracing:
    added server file logging
    added log file rotation

Minor renames.

Contributes to: #42211 and #42198

Adds a new flowgraph checker that tries to verify that the profile data is
self-consistent.

Use `COMPlus_JitProfileChecks=1` to enable in dumps, `=2` to raise asserts
if issues are found.

I plan on using this to start fixing the issues it finds and then perhaps
gradually enable more stringent checking.

…bid-suspend-for-debugger region (#42587)

- Followup to dotnet/runtime#40060
- In short timing windows if a thread is placed in a pending-suspend-for-debugger state while in a forbid-suspend-for-debugger region, from the above PR it would not suspend for the debugger but it was missed that it can also get stuck in a perpetual spin-wait while entering cooperative GC mode. This causes the thread to not suspend for the debugger (VS times out after waiting) and the thread can only progress by unmarking it for debugger suspension.
- Fixed to break the spin-wait by checking whether the thread is in the forbid region

Fix for dotnet/runtime#42375 in master

* Return null from ClaimsPrincipal.Current if no thread principal.

In the .NET Framework, the AppDomain's default PrincipalPolicy is
UnauthenticatedPrincipal. When falling back to the thread's principal,
this would no throw because a GenericPrincipal was returned.
If the policy was changed to NoPrincipal, ClaimsPrincipal.Current would
throw constructing the ClaimsPrincipal since there is no principal.
However that behavior was opt-in.

In .NET Core, the default policy was changed to NoPrincipal, which would
mean unless a principal was explicitly set, Current would always throw.

This changes the behavior to return null instead of throw for
NoPrincipal. This is to continue supporting the existing behavior in
.NET Core 3 of returning null if there is no principal, but continue
to allow falling back to the thread's principal.

* Delete unused Monitor.Wait argument

*  Move Monitor to shared partition

We experience CLR crash on some architectures (at least in x86) in case
of unhandled managed exception. libunwind steps to the very end of a
stack, and if .eh_frame info is correct, it returns with retcode 0 and
ip=0 from unw_step, then PAL calls unw_is_signal_frame with
c->validate==0 which in turn dereferences zeroed ip in access_mem.
libunwind spec says that retcode 0 from unw_step means very end of a
stack, so PAL should not expect any frames, signal or not. It should
convert cursor back to SEH representation and return with TRUE.

* Ensure Enumerable methods are preserved by System.Linq.Querable

When using System.Linq.Queryable against an in-memory collection, and trimming the application, the underlying Enumerable methods need to be preserved by the linker.

Annotating each Queryable method with a DynamicDependency to the corresponding Enumerable method will fix this scenario.

Fix #42536

Change the `-altjit` flag to require passing a JIT filename. There are
too many altjits (cross-compile JITs) available now to be able to pick
a good default, so force the user to pick.

* Support cp1252 codepage alias

* Apply suggestions from code review
