* pkg/terminal: support ctrlz for shell job control
This required forking peterh/liner under the go-delve org and using that
instead since upstream is not open to supporting this feature.
Fixes#2157
* Update liner
* Update liner but correctly this time
* upgrade golang.org/x/tools to 0.1.9
* 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.
We forgot to run typecheckrpc.go periodically and it didn't work
anymore and there were some minor errors in service/rpc2/client.go.
Rewrite typecheckrpc.go using go/packages, so that it works with go1.11
and go.mod, and fix the issues in client.go
