* service/dap: remove deadlock in TestLaunchDebugRequest
Fixes#2746
* terminal: fix TestScopePrefix flakiness
When there are more than 10 frames api.PrintStack will prefix the
output with spaces to right justify the frame number, which confuses
TestScopePrefix.
* _scripts: pass -buildvcs for Go 1.18 and later on TeamCity
Go 1.18 will try to stamp builds with the VCS version, this doesn't
work on TeamCity because the checkout isn't a valid repository (but
looks like it).
Pass -buildvcs=false to disable this feature.
* proc: switch to goroutine stack if first frame's func can not be found
If the first frame on the system stack can not be resolved to a
function switch directly to the goroutine stack.
