Some C APIs require the use or structures that contain pointers to
buffers (iovec, io_uring, ...). The pointer passing rules would
require that these buffers are allocated in C memory and to process
this data with Go libraries it would need to be copied.
In order to provide a zero-copy way to use these C APIs, this CL
implements a Pinner API that allows to pin Go objects, which
guarantees that the garbage collector does not move these objects
while pinned. This allows to relax the pointer passing rules so that
pinned pointers can be stored in C allocated memory or can be
contained in Go memory that is passed to C functions.
The Pin() method accepts pointers to objects of any type and
unsafe.Pointer. Slices and arrays can be pinned by calling Pin()
with the pointer to the first element. Pinning of maps is not
supported.
If the GC collects unreachable Pinner holding pinned objects it
panics. If Pin() is called with the other non-pointer types it
panics as well.
Performance considerations: This change has no impact on execution
time on existing code, because checks are only done in code paths,
that would panic otherwise. The memory footprint on existing code is
one pointer per memory span.

Add a struct called Source that holds the function, file and line
of a location in the program's source code.
When HandleOptions.AddSource is true, the ReplaceAttr function will
get an Attr whose key is SourceKey and whose value is a *Source.
We use *Source instead of Source to save an allocation. The pointer
and the value each cause one allocation up front: the pointer when it
is created, and the value when it is assigned to the `any` field of a
slog.Value (handle.go:283). If a ReplaceAttr function wanted to modify
a Source value, it would have to create a new slog.Value to return,
causing a second allocation, but the function can modify a *Source in
place.
TextHandler displays a Source as "file:line".
JSONHandler displays a Source as a group of its non-zero fields.
This replaces the previous design, where source location was always a
string with the format "file:line". The new design gives users more
control over how to output and consume source locations.

This new TCPConn method returns whether the connection is using MPTCP or
if a fallback to TCP has been done, e.g. because the other peer doesn't
support MPTCP.
When working on the new E2E test linked to MPTCP (#56539), it looks like
the user might need to know such info to be able to do some special
actions (report, stop, etc.). This also improves the test to make sure
MPTCP has been used as expected.
Regarding the implementation, from kernel version 5.16, it is possible
to use:
getsockopt(..., SOL_MPTCP, MPTCP_INFO, ...)
and check if EOPNOTSUPP (IPv4) or ENOPROTOOPT (IPv6) is returned. If it
is, it means a fallback to TCP has been done. See this link for more
details:
https://github.com/multipath-tcp/mptcp_net-next/issues/294
Before v5.16, there is no other simple way, from the userspace, to check
if the created socket did a fallback to TCP. Netlink requests could be
done to try to find more details about a specific socket but that seems
quite a heavy machinery. Instead, only the protocol is checked on older
kernels.
The E2E test has been modified to check that the MPTCP connection didn't
do any fallback to TCP, explicitely validating the two methods
(SO_PROTOCOL and MPTCP_INFO) if it is supported by the host.

For #57001, compilers and others tools will need to understand that
a different Go version can be used in different files in a program,
according to the //go:build lines in those files.
This CL adds a GoVersion string field to ast.File, to allow exposing this
per-file Go version information.
For #59033.

For #57001, programs need to be able to deduce the Go version
implied by a given build constraint. GoVersion determines that,
by discarding all build tags other than Go versions and computing
the minimum Go version implied by the resulting expression.
For #59033.

Per https://go.dev/wiki/Deprecated, we must wait until Go 1.21
to mark them deprecated.
