proc,proc/*: add StopReason field to Target (#1877)
* proc,proc/*: move SelectedGoroutine to proc.Target, remove PostInitializationSetup

moves SelectedGoroutine, SwitchThread and SwitchGoroutine to
proc.Target, merges PostInitializationSetup with NewTarget.

* proc,proc/*: add StopReason field to Target

Adds a StopReason field to the Target object describing why the target
process is currently stopped. This will be useful for the DAP server
(which needs to report this reason in one of its requests) as well as
making pull request #1785 (reverse step) conformant to the new
architecture.

* proc: collect NewTarget arguments into a struct

*: Go 1.14 support branch (#1727)
* tests: misc test fixes for go1.14

- math.go is now ambiguous due to changes to the go runtime so specify
  that we mean our own math.go in _fixtures
- go list -m requires vendor-mode to be disabled so pass '-mod=' to it
  in case user has GOFLAGS=-mod=vendor
- update version of go/packages, required to work with go 1.14 (and
  executed go mod vendor)
- Increased goroutine migration in one development version of Go 1.14
  revealed a problem with TestCheckpoints in command_test.go and
  rr_test.go. The tests were always wrong because Restart(checkpoint)
  doesn't change the current thread but we can't assume that when the
  checkpoint was taken the current goroutine was running on the same
  thread.

* goversion: update maximum supported version

* Makefile: disable testing lldb-server backend on linux with Go 1.14

There seems to be some incompatibility with lldb-server version 6.0.0
on linux and Go 1.14.

* proc/gdbserial: better handling of signals

- if multiple signals are received simultaneously propagate all of them to the
  target threads instead of only one.
- debugserver will drop an interrupt request if a target thread simultaneously
  receives a signal, handle this situation.

* dwarf/line: normalize backslashes for windows executables

Starting with Go 1.14 the compiler sometimes emits backslashes as well
as forward slashes in debug_line, normalize everything to / for
conformity with the behavior of previous versions.

* proc/native: partial support for Windows async preempt mechanism

See https://github.com/golang/go/issues/36494 for a description of why
full support for 1.14 under windows is problematic.

* proc/native: disable Go 1.14 async preemption on Windows
