Allows for a user to specify the breakpoint condition directly
when creating the breakpoint. The new syntax looks like the
following:
```
break <name> <locspec> [if <expression>]
```
Also updates docs to include more examples and locspec description
instead of directing users to the online / source documentation.
Change FindLocation so it can return a substitute location expression
and propagate it to pkg/terminal/command.
When breakpoints are set using the syntax :<lineno> or +<lineno>
produce a substitute location expression that doesn't depend on having
a valid scope and can be used to restore the breakpoint.
Fixes#3423
A series of interconnected changes to both the terminal command
'config', DAP command 'dlv config', quality of life improvements to how
substitute-path works, and better documentation.
- Let 'config substitute-path' show the current substitute path rules
- Add a -clear command to 'config substitute-path'
- Support 'config-debug-info-directories'
- rewrite SubstitutePath to be platform independent (see below)
- document path substitution more
Regarding the rewrite of SubstitutePath: the previous version used
runtime.GOOS and filepath.IsAbs to determine which filepath separator to use
and if matching should be case insensitive. This is wrong in all situations
where the client and server run on different OSes, when examining core files
and when cross-compilation is involved.
The new version of SubstitutePath checks the rules and the input path to
determine if Windows is involved in the process, if it looks like it is it
switches to case-insensitive matching. It uses a lax version of
filepath.IsAbs to determine if a path is absolute and tries to avoid having
to select a path separator as much as possible

The compiler produces ABI compatibility wrappers for some functions.
We have changed the support for breakpoints to allow a single logical
breakpoint to correspond to multiple physical breakpoints, take
advantage of that to set breakpoints on both the ABI wrapper and the
real function.
Fixes#3296
Changes FindLocation to support multiple targets and adds an AddrPid
member to api.Breakpoint so that clients can set breakpoints by address
when multiple targets are connected (but at them moment this field is
ignored).
Updates #1653
Updates #2551
This changes adds the support to replace relative paths sources with "" as rapresenting current directory.
For example:
Rule like '{from: "", to: "/my/project"}' will map path "src/my/code.go" into "/my/project/src/my/code.go"
Rule like '{from: "/my/project", to: ""}' will map path "/my/project/src/my/code.go" into "src/my/code.go"
Fixes#3082
In order to support substituting a single file within
a larger package, and not substituting a directory wholesale,
this commit introduces the ability for SubstitutePath
to replace individual file paths if there is an exact match.
This behavior is backwards-compatible with the previous
configuration.
Fixes#3074
Go 1.19 also formats doc comments according to the new godoc syntax.
Some of our comments, especially unexported symbols did not conform to
the godoc syntax and therefore are mangled by 'go fmt'.
This PR runs 'go fmt' from go1.19 on everything and manually fixes the
problems.

* proc,locspec: support setting breakpoints by func name on generic funcs
Changes proc.Function to parse function names correctly when they
contain instantiation lists and locspec to match generic functions.
* vendor: update golang.org/x/tools
The old version of golang.org/x/tools is incompatible with the new
iexport format.
* Reformat pkg/locspec documentation so that it is formatted correctly
by godoc/pkgsite
* Unexport some types and variables in proc that don't need to be
exported.
* cmd/dlv,debugger: Improve dlv trace and trace command output
This patch improves the `dlv trace` subcommand output by reducing the
noise that is generated and providing clearer more concise information.
Also adds new tests closing a gap in our testing (we previously never
really tested this subcommand).
This patch also fixes the `dlv trace` REPL command to behave like the
subcommand in certain situations. If the tracepoint is for a function,
we now show function arguements and return values properly.
Also makes the overall output of the trace subcommand clearer.
Fixes#2027
