pkg/proc: do not check decl line for FunctionArguments (#3254)
Fixes a bug where we cannot get locals (including arguments and return
values) from a given scope because the line number state machine ends up
in an invalid state because of this parameter being set to false.

cmd/dlv: match go test behavior when dlv test gets a list of .go files (#3232)
When 'dlv test' is called with a list of files it should match the
behavior of 'go test' and chdir to the directory where the go files are
(if they are all in the same directory).

Fixes #3230

proc/native: fix FreeBSD backend (#3224)
- use PT_SUSPEND/PT_RESUME to control running threads in
  resume/stop/singleStep
- change manual stop signal from SIGTRAP to SIGSTOP to make manual stop
  handling simpler
- change (*nativeProcess).trapWaitInternal to suspend newly created
  threads when we are stepping a thread
- change (*nativeProcess).trapWaitInternal to handle some unhandled
  stop events
- remove misleading (*nativeProcess).waitFast which does not do
  anything different from the normal wait variant
- rewrite (*nativeProcess).stop to only set breakpoints for threads of
  which we have received SIGTRAP
- rewrite (*nativeThread).singleStep to actually execute a single
  instruction and to properly route signals

*: early fixes for go1.20 (#3180)
- updated go/packages to support new export format
- rewrite testinline.go fixture because the compiler got too smart with
  constant folding
- temporarily disable staticcheck on go1.20 because it doesn't support
  the new export format.
- workaround for go.dev/cl/429601

cmd/dlv: Include hidden flag -c for coredumpctl support (#3195)
`coredumpctl` attempts to pass the core file to the debugger through the `-c`
flag. However delve does not support such a flag.

This patch makes it a bool flag so we can receive the coredump file from
`coredumpctl`

cmd/dlv: add --client-addr flag to run dap with a predefined client (#2568)
This adds a new `--client-addr=host:port` flag to `dlv dap`.
If it is supplied, the dap process will dial into the tcp port where
a DAP client is waiting, and work with only the DAP client.
The DAP client is supposed to start the normal DAP message
exchange starting with the 'initialize' request after the dlv dap
process dials in and the connection is set up. 

VS Code Go extension plans to use this mode for

* reliably detecting `dlv dap` readiness. Currently it depends on
watching the log stream. After this PR, it can listen on a network port.
* running `dlv dap` from any terminal (part of RunInTerminal workflow
implementation).

cmd/dlv: dlv version --verbose (#2615)
* cmd/dlv: dlv version --verbose

That prints out runtime/debug.BuildInfo read from the dlv binary.
Users can retrieve the same info using `go version -m <path_to_dlv>`
but I think it is convenient to have.

If dlv was built from cloned delve repo:

```
$ ./dlv version -v
Delve Debugger
Version: 1.7.0
Build: $Id: e353a65161e6ed74952b96bbb62ebfc56090832b $

 dep    github.com/cosiner/argv v0.1.0  h1:BVDiEL32lwHukgJKP87btEPenzrrHUjajs/8yzaqcXg=
...
```

If dlv was built with `go install github.com/go-delve/delve@latest`
with go1.16+, or
`GO111MODULE=on go get github.com/go-delve/delve@latest`
from a clean main module:

```

service/dap: Support for replay and core modes (#2367)
This PR aims to add support for rr replay and core actions from the DAP layer. This basically encloses the following:
New launch modes: replay and core

The following modes are added:

    replay: Replays an rr trace, allowing backwards flows (reverse continue and stepback). Requires a traceDirPath property on launch.json pointing to a valid rr trace directory.
    Equivalent to dlv replay <tracedir> command.
    core: Replays a core dump file, showing its callstack and the file matching the callsite. Requires a coreFilePath property on launch.json pointing to a valid coredump file.
    Equivalent to dlv core <exe> <corefile> command.

Dependencies

To achieve this the following additional changes were made:

    Implement the onStepBackRequest and onReverseContinueRequest methods on service/dap
    Adapt onLaunchRequest with the requried validations and logic for these new modes
    Use CapabilitiesEvent responses to enable the StepBack controls on the supported scenarios (see dicussion here)
    Add the corresponding launch.json support on vs code:
