A mistake I've repeatedly made is along these lines:
```c++
auto nread = TRY(source_file->read(buffer));
TRY(destination_file->write(buffer));
```
It's a little clunky to have to create a Bytes or StringView from the
buffer's data pointer and the nread, and easy to forget and just use
the buffer. So, this patch changes the read() function to return a
Bytes of the data that were just read.
The other read_foo() methods will be modified in the same way in
subsequent commits.
Fixes #13687

This prevents a crash when the inspected process closes the socket (i.e.
when the app is exited). This crash was caused by the InspectableProcess
removing itself from the global process table within a callback Function
that is stored as part of the InspectableProcess.

"The compiler is more likely to get the default semantics right and
you cannot implement these functions better than the compiler."

Apologies for the enormous commit, but I don't see a way to split this
up nicely. In the vast majority of cases it's a simple change. A few
extra places can use TRY instead of manual error checking though. :^)

This change unfortunately cannot be atomically made without a single
commit changing everything.
Most of the important changes are in LibIPC/Connection.cpp,
LibIPC/ServerConnection.cpp and LibCore/LocalServer.cpp.
The notable changes are:
- IPCCompiler now generates the decode and decode_message functions such
that they take a Core::Stream::LocalSocket instead of the socket fd.
- IPC::Decoder now uses the receive_fd method of LocalSocket instead of
doing system calls directly on the fd.
- IPC::ConnectionBase and related classes now use the Stream API
functions.
- IPC::ServerConnection no longer constructs the socket itself; instead,
a convenience macro, IPC_CLIENT_CONNECTION, is used in place of
C_OBJECT and will generate a static try_create factory function for
the ServerConnection subclass. The subclass is now responsible for
passing the socket constructed in this function to its
ServerConnection base; the socket is passed as the first argument to
the constructor (as a NonnullOwnPtr<Core::Stream::LocalServer>) before
any other arguments.
- The functionality regarding taking over sockets from SystemServer has
been moved to LibIPC/SystemServerTakeover.cpp. The Core::LocalSocket
implementation of this functionality hasn't been deleted due to my
intention of removing this class in the near future and to reduce
noise on this (already quite noisy) PR.

`length` was inheriting `size_t` type of the `String::length()`, while
everywhere else in the Inspector we expect fixed 32-bit field. On the
architectures where `sizeof(size_t) != sizeof(u32)` this broke the
Inspector communication completely.

Same as Vector, ByteBuffer now also signals allocation failure by
returning an ENOMEM Error instead of a bool, allowing us to use the
TRY() and MUST() patterns.
|
|
If we can easily communicate failure, let's avoid asserting and report
failure instead.
|
|
This fixes a few compiler warnings and makes some variables const-ref
in preparation for the next commit which changes how ByteBuffer works.

This service daemon will act as an intermediary between the Inspector
program and the inspectable programs it wants to inspect.
Programs can make themselves available for inspection by connecting
to /tmp/portal/inspectables using the Core::EventLoop RPC protocol.
