* dap: handle SetVariable requests
The handler invokes debugger.SetVariableInScope, except for
string type variables. For which, we rely on the `call` command.
Moved the call expression handling logic to the new `doCall`
function, so it can be reused by the SetVariable requenst
handler.
With this PR, every successful SetVariable request triggers
a StoppedEvent - that's a hack to reset the variablesHandle
map internally and notify the client of this change. It will
be nice if we can just update cached data corresponding to
the updated variable. But I cannot find an easy and safe way
to achieve this yet.
Also fixed a small bug in the call expression evaluation -
Previously, dlv dap returned an error "Unable to evaluate
expression: call stopped" if the call expression is for
variable assignment. (e.g. "call animal = "rabbit").
* dap: address comments from aarzilli
resetHandlesForStop & sendStoppedEvent unconditionally after
call command is left as a TODO - This is an existing code path
(just refactored) and an preexisting bug. Fixing it here
requires updates in TestEvaluateCallRequest and I prefer
addressing it in a separate cl.
Disabled call injection testing on arm64. Separated TestSetVariable
into two, one that doesn't involve call injection and another that
may involve call injection.
Fixed variableByName by removing unnecessary recursion.
* dap: address polina's comments
- removed the hard reset for every variable set
- added tests for various variable types
- added tests that involves interrupted function calls. (breakpoint/panic)
And,
- changed to utilize EvalVariableInScope to access the variable instead
of searching the children by name.
- changed to utilize evaluate requests when verifying whether the variable
is changed as expected in testing. Since now we avoid resetting the variable
handles after variable reset, either we need to trigger scope changes
explicitly, or stop depending on the variables request.
* dap: address comments
- Discuss the problem around the current doCall implementation
and the implication.
- Refine the description on how VS Code handles after setVariable
and evaluate request (there could be followup scopes/evaluate requests).
- Use the explicit line numbers for breakpoints in the SetVariable tests.
- Do not use errors.Is - we could've used golang.org/x/xerrors polyfill
but that's an additional dependency, and we will remove this check once
tests that depend on old behavior are fixed.

* service/dap: support pause request
* service/dap: validate the client configurations in initialize request (#2435)
The client can specify certain configurations in the initialize request.
For example, pathFormat determines the pathFormat. We do not currently
support configuring pathFormat, linesStartAt1, or columnsStartAt1, so
we report an error if the client attempts to set these to an
unsupported value.
* TeamCity: fix Windows builds (#2467)
Bintray is shutting down and the URL we used to install mingw is no
longer available. Use chocolatey instead.
* proc/native: low level support for watchpoints in linux/amd64 (#2301)
Adds the low-level support for watchpoints (aka data breakpoints) to
the native linux/amd64 backend.
Does not add user interface or functioning support for watchpoints
on stack variables.
Updates #279

daptest has type assertion functions that panic
if the read response/event message is not
the expected type. This is not only against the
recommended style guideline (Don't Panic, Useful
Test Failures, ...), but also it prevents from
quickly diagnosing test failures occurred in remote
CIs.
This PR changes the type assertion to the two
return value type assertion, and t.Fatal with details
if the type is not expected.
service/dap/daptest/main.go is a program that auto
generates those assertion functions in resp.go.
Run `go generate` from the service/dap directory
to update resp.go.
The client can specify certain configurations in the initialize request.
For example, pathFormat determines the pathFormat. We do not currently
support configuring pathFormat, linesStartAt1, or columnsStartAt1, so

unsupported value.

This helps avoid spurious error logs when the client disconnects, when
