Martin Kustermann 698bf0846b [vm] Hoist CStringUniquePtr out of Utils, add CAllocUniquePtr` to simplify code
Hoist `CStringUniquePtr` out of the `Utils` class as there
is no reason it has to be nested inside a class - it just makes
code more verbose.

This simplifies code of the form
   std::unique_ptr<T, decltype(std::free)> a = { nullptr, std::free };
to
   CAllocUniquePtr<T> a;

Daco Harkes f98a2138b7 [vm] Run clang-format on code base
When uploading CLs, the presubmit checks verify that the lines in the
diff are formatted correctly according to `git cl format runtime`.

However, when `buildtools/<os>-<arch>/clang/bin/clang-format` is
updated, it does not force reformatting of files that would be
reformatted.

This leads to two issues:
* Inconsistent style within the code base and within a single file.
* Spurious reformatting in CLs when (1) clang-format is used on the
  whole file, or (2) the diff lines overlap.

`clang-format` doesn't change that frequently, so in general this is
not a large issue, but I've seen a bit too many "spurious formatting,
please revert" comments on CLs recently.

This CL formats the runtime to be in line with the current pinned
`clang-format`:

```
$ find runtime/ -iname *.h -o -iname *.cc | xargs buildtools/mac-arm64/clang/bin/clang-format -i
```

`git cl format` (which only formats changed lines, and does so with
`clang-format`) seems to not agree with itself, or clang-format, or
cpplint in a handful of places. This CL adds `// clang-format off`
for these. (See previous patchsets for the specific instances.)

Tess Strickland 6ef426d7df MacOS-Signable Compiled Dart Scripts
This CL implements a slightly altered compilation process for `dart
compile` on MacOS. Instead of the traditional approach of
concatenating a dart snapshot with the dart runtime, this new
implementation uses a new MachO segment to store the snapshot. Doing
so ensure users can properly sign the resulting binaries.

The dart runtime has also been updated to look for the snapshots in
this new segment.

There are new unit tests ensuring the dart runtime can correctly
identify MachO-formatted executables and an end-to-end test ensuring
`dart compile` produces code that has the new segment and produces
code that can be signed.

Alexander Aprelev 935ee25f3b [io/unix_domain_socket] Add support for sending/receiving open files, sockets, std streams via sockets.
This adds [sendMessage] and [receiveMessage] methods to [RawSocket] class. They are only supported on Linux at the moment as they require connection opened as unix domain socket connection.

This introduces [SocketControlMessage] class that represents a message sent via socket and also introduces [ResourceHandle] class that wraps [RandomAccessFile], [Socket]/[RawSocket]/[RawDatagramSocket], [Stdin]/[Stdout] for
marshalling/unmarshalling purposes.

Underlying OS implementation supports various kinds of control messages that can be passed via sockets, this CL only adds support for sending/receiving opened file description handles.
When receiving a message recipient can attempt to extract handles out of it via [tryExtractHandles]. It returns [null] if message has no handles to extract.

This is continuation of the work started on https://dart-review.googlesource.com/c/sdk/+/205067.

Zach Anderson f407419d0a [vm] Reland: Prefix HOST_OS_* and TARGET_OS_* with DART_
This relands https://dart-review.googlesource.com/c/sdk/+/205633
but without renaming TARGET_OS_IPHONE to DART_TARGET_OS_IPHONE.
It also changes uses of TARGET_OS_IOS to
DART_TARGET_OS_MACOS_IOS to be consistent with the rest of the
VM.

TargetConditionals.h for XCode 13 defines several
TARGET_OS_* preprocessor symbols that confuse the
Dart build. There is probably a more targeted fix
for this, but renaming the symbols that Dart uses
will also prevent this problem if more symbols
are added to the platform headers in the future.

Ryan Macnak d9f9b4dc96 [vm] Try to allocate snapshots and executable heap pages near the VM's binary.
Some 64-bit microarchitectures store only the low 32-bits of targets as part of indirect branch prediction, predicting that the target's upper bits will be the same as the call instruction's address. This leads to misprediction for indirect calls crossing a 4GB boundary. Ask mmap to place our generated code near the VM binary to avoid this.

Zichang Guo ed83a28d3e [dart:io] support Unix domain communications
Support Unix domain sockets communication on Linux, MacOS and Android.

Changes:
1. Add a field for InternetAddressType named unix.
2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type});
3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type});

The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.

different handles to use for stdout and stderr. This change provides
a hook for an embedder to call to supply the handles to Dart, and
removes hardcoding of stdio handles to 0, 1, 2.

Zachary Anderson d0295c873c [dart:io] Namespaces for file IO
Fuchsia requires the ability to sandbox Isolates w.r.t. file IO.
When a new Isolate starts, Fuchsia will pass the Isolate an object
called a namespace. We can translate the namespace object into a
file descriptor suitable for passing to the *at() family of
POSIX file system calls. The file system calls will then
have visibility only into the specified namespace.

We also plumb Namespaces through on all the other platforms as well to
make the change easier to test and so that in the future we can
implement e.g. per-isolate cwds.

This change adds a new internal class to dart:io called _Namespace,
which is implemented in a patch file. See:

sdk/lib/io/namespace_impl.dart
runtime/bin/namespace_patch.dart

The embedder can set up a non-default namespace by calling
_Namespace._setupNamespace during Isolate setup.

Instances of _Namespace have a native field that holds a pointer
to a native Namespace object. See:

runtime/bin/namespace.h

Calls from e.g. file_impl.dart are now also passed a
_Namespace object. The implementations in e.g. file.cc and
file_linux.cc then extract the namespace, and use it to compute a
file descriptor and path suitable for passing to e.g. openat().

Zachary Anderson 8c9c54d833 [dart:io] Don't close stdin with a socket finalizer
If an Isolate touches the 'stdio' getter, a _NativeSocket with
attached finalizer is created for it. Previously, when such an
Isolate exited, the finalizer would close the underlying
file descriptor. This CL changes the finalizer for stdin such
that the native objects will be cleaned up, but the underlying
file descriptor will not be closed. The underlying file
descriptor will now only be closed if the stdin stream
subscription is explicitly canceled.

Accessing the stdin getter after the stream is explicitly
canceled will result in a FileSystemException.

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.

Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.
