Some of the fixes done for the warnings have breaking changes. Move back
to int and ensure that we do not have any compilation errors (we are
using -Werror).

It's possible for a nuget to have dependencies that will bring satellite
assemblies into a project.
When doing so the satellite assemblies are copied to the right output
(e.g. `Debug`) directory, so they work fine at runtime. However it's
not 100% fine at build time, e.g. msbuild won't detected them as
satellite assemblies.
Something similar happens with `mtouch` (and `mmp`) since the satellite
assemblies won't be found inside a (culture-named) subdirectory from the
original assembly location. In our case this means the assemblies won't
be copied into the .app bundle (since we don't run from `Debug`) and
localization won't work properly.
The solution is to check for both the (culture-named) subdirectories
from the assembly location (like before) and, if nothing is found, also
try to locate them in the _build_ (like `Debug`) directory - so if
something else (nuget or custom build scripts) tried to outsmart the
build logic then we'll still bring those satellite assemblies in the
app bundle we produce.

The nice, repeatable test case from #7514 pointed out two issues
1. `cache.cs` ignored some changes
It looks like something changed (at some point) and the first _ignored_
line was the `@x.rsp` our response file - which should not be ignored.
This solved the build issue where updating the nuget should have
triggered a rebuild because
> /Users/poupou/.nuget/packages/skiasharp/1.68.0/lib/Xamarin.iOS/SkiaSharp.dll
and
> /Users/poupou/.nuget/packages/skiasharp/1.68.1/lib/Xamarin.iOS/SkiaSharp.dll
are different assemblies (but the same response file).
2. `copyfile` could fail silently
Copying the framework could fail (error 260) and the failure was never
reported so the build succeeded - but without updating (completely) the
framework.
The exact reason it fails is unknown :( but we can recover from it by
deleting the target and copying (everything) back to the expected
(target) location.
Build logs will now indicate when this fails and will try to recover
before reporting a build error. Best case it works :) worse case we'll
be aware something is wrong (which is better than ignoring)

* Do not call `Marshal.GetLastWin32Error` instead the callback
as the `SetLastError` logic has yet to be executed so we get a bogus
`260` value...
Instead we call it after the `copyfile` call returns but, at this stage,
the callback (i.e. **us**) signaled an error so what we get back (`17`)
is not very helpful - as we aborted (Quit) the logic when copying a file
that existed.
```c
#define EEXIST 17 /* File exists */
```
from Console logs
```
default 14:23:54.771292-0500 mono64 Cannot make directory /Users/poupou/Projects/gh7514/gh7514/bin/iPhoneSimulator/Debug/gh7514.app/Frameworks/libSkiaSharp.framework: File exists

```
`copyfile.c` source code (might not be the latest) can be seen from
https://opensource.apple.com/source/copyfile/copyfile-42/copyfile.c
```c
if (mkdir(s->dst, mode) == -1) {
if (errno != EEXIST || (s->flags & COPYFILE_EXCL)) {
copyfile_warn("Cannot make directory %s", s->dst);
```
so `mkdir` fails - but not because of `EEXIST` and from `copyfile.h`
we see that `EXCL` exists but it's not using (or even defined) in our
bindings.
```c
#define COPYFILE_EXCL (1<<17) /* fail if destination exists */
```
So sadly the `Err` condition (inside the callback) does not give us more
detail about the error itself.
1. Instead of fetching the managed response's cookies twice, and then
comparing them to themselves, fetch the managed response's cookies once and
then the native response's cookies once, and compare that. This way the
test does what it's actually supposed to do!
2. Don't pass if we fail to get the managed response's cookies.
3. Improve assertions to verify the actual cookie content as well.
4. Improve diagnostics if an exception was thrown by checking for the
exception first instead of failing due to something else being different
(since the underlying cause of the difference is the exception, that's what
will have the most information about the failure).
5. Use httpbin.org instead of microsoft.com, since microsoft.com does UA
sniffing and returns different results between the http handlers :/
## Miscellaneous fixes

## Bring HttpClient from CoreFX
* #7346
* This bumps Mono to use https://github.com/mono/mono/pull/17645 (which is the 2019-10 backport
of https://github.com/mono/mono/pull/17628).
* The big user-visible change is in regards to certificate validation, everything below are just
some minor adjustments to tests.
### SocketsHttpHandler
CoreFX uses a completely new `HttpClientHandler` implementation called `SocketsHttpHandler`,
which you can find at https://github.com/dotnet/corefx/tree/release/3.0/src/System.Net.Http/src/System/Net/Http/SocketsHttpHandler.
Since this is not based on the web stack anymore, it does not use any of the related APIs such
as `ServicePointManager` or `WebException`.
### Certificate Validation Changes
There is a new API called `HttpClientHandler.ServerCertificateCustomValidationCallback`.
- https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclienthandler.servercertificatecustomvalidationcallback?view=netframework-4.8
- c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Unix.cs (L154)
- c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Windows.cs (L383)
The `ServicePointManager.ServerCertificateValidationCallback` is no longer invoked and on
certificate validation failure, `AuthenticationException` (from `System.Security.Authentication`)
is thrown instead of `WebException`.
At the moment, the `NSUrlSessionHandler` still uses it's own validation callback and also still
throws `WebException` on failure; we should probably look into making this consistent with the
other handlers.
### Minor adjustments related to internal Mono APIs
* `HttpContent.SerializeToStreamAsync()` is now `protected` (changed from `protected internal`).
- src/Foundation/NSUrlSessionHandler.cs: changed overload accordingly.
- src/System.Net.Http/CFContentStream.cs: likewise.
* `HttpHeaders.GetKnownHeaderKind()` is an internal Mono API.
There is a new internal API called `System.Net.Http.PlatformHelper.IsContentHeader(key)`
which exists in both the old as well as the new implementation.
The correct way of doing it with the CoreFX handler is
`HeaderDescriptor.TryGet (key, out var descriptor) && descriptor.HeaderType == HttpHeaderType.Content`
### Minor adjustments to tests.
* `HttpClientHandler.MaxRequestContentBufferSize` is now longer supported, you can set it to
any non-negative value, the getter will always return 0.
See c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Core.cs (L18).
- tests/linker/ios/link sdk/HttpClientHandlerTest.cs: removed assertion from test.
* `HttpMessageInvoker.handler` is a `protected private` field - in the CoreFX handler, it is
called `_handler` and `private`. This is accessed via reflection by some of the tests, which are
now using the new name.
- tests/mmptest/src/MMPTest.cs: here
- tests/mtouch/MTouch.cs: here
* tests/monotouch-test/System.Net.Http/MessageHandlers.cs:
Adjust `RejectSslCertificatesServicePointManager` to reflect the certificate validation
changes described above.
- FIXME: There was an `Assert.Ignore()` related to `NSUrlSessionHandler` and macOS 10.10;
I removed that to reenable the test because the description linked to an old issue in
the private repo that was referenced by several "Merged" PR's, so it looked to me that
this might have already been fixed - and I also didn't see why it would fail there.
**Problem**
32 bit tests could only be executed with 64 bit tests. E.g: `run-ios-32-tests` didn't work on its own, only `run-ios-tests,run-ios-32-tests` worked
**Solution**
- Change the logic so that 32 bit tests are only looking for `IncludeiOS32` and 64 bit tests only `IncludeiOS64`
- To keep `run-ios-tests` and `skip-ios-tests` working, hack `SetEnabled` so `IncludeiOS` also sets `IncludeiOS32` and `IncludeiOS64`.
Otherwise the way the code is currently organised we'd have to use `skip-ios-32-tests` and `skip-ios-64-tests`.
Keep 'CallContextSecurityData' around since it's quite small (and the
normal linker logic will be able to deal with it if unused) and allows
the use of `Thread.CurrentPrincipal`
Also add unit test.

and drop the manual, error prone, conversion code.
The fact that this is also used as a `[Flag]` enum does not mean smart
enum could not be used [1]. The flag code only needed to be updated to
use the smart enum generated code.

`Create` methods give ownership of the object, so in this case, owns=true. Prevents leak of CFHTTPAuthentication

The linking tests do use a number of endpoints.
As with PR https://github.com/xamarin/xamarin-macios/pull/7418 we want
to have all the endpoints in a single place to update them if the server
side does give us problems.
Turn older #7165 prototype into an experimental feature. It can be

If forcing a managed type for a particular native handle, we must ensure we're
always successful.
This means creating another managed instance even if there already is an
existing instance for the native handle. This is not optimal, but the
alternative is worse: some functionality can be completely broken otherwise
(such as NSSavePanel⁄NSOpenPanel may stop working).
If creating multiple managed instances for the same native handle ends up
being too problematic, we'll probably have to add full support for this
scenario (see #7442).
Fixes https://github.com/xamarin/xamarin-macios/issues/7441.
Static analysis (and any manual review) is easily confused by
`sizeof (id)`, `sizeof (self)` and `sizeof (*self)` when another
argument is `self` and can report false positives (or be missed
or misinterpreted by humans).
This simply clarify that `|` is an encoded pointer and will
be the size of the pointer (varying by architectures)
Use a single point where the different enpoints can be found so that
if they need to be updated (server issues or other) it is a simple
change that will affect all tests in monotouch-tests
`xamarin_notify_dealloc` can throw an exception (depending on the mode
used).
Throwing exception in a destructor is problematic in [Obj]C++ and can
abort the application. That might be fine in some cases but there's
not much point in doing so when we're about to forget everything about
that specific object.
The initial solution fixed the rance condition in which the index
changed, but that did not guarantee that we would get the correct
bundles. We now clone the CFArray (which also clones the callbacks set
to the array) and iterate over it to make sure Apple does not do evil
tings while we are iteraing.
Better Fixes: https://github.com/xamarin/maccore/issues/940
Help static analyzer by clarifying that only `char` will be given to
`isblank` so it does not look like it could be used to index an array
and gets out of bounds (important since this is user supplied values).
Digging down into `isblank` will get you to
