This patch enables the eBPF tracer backend to parse the ID of the
Goroutine which hit the uprobe. This implementation is specific to AMD64
and will have to be generalized further in order to be used on other
architectures.

Works around https://github.com/golang/go/issues/47367.

* proc: support new Go 1.17 panic/defer mechanism

Go 1.17 will create wrappers for deferred calls that take arguments.
Change defer reading code so that wrappers are automatically unwrapped.

Also the deferred function is called directly by runtime.gopanic, without going through runtime.callN which means that sometimes when a panic happens the stack is either:

0. deferred function call
1. deferred call wrapper
2. runtime.gopanic

or:

0. deferred function call
1. runtime.gopanic

instead of always being:

0. deferred function call
1. runtime.callN
2. runtime.gopanic

the isPanicCall check is changed accordingly.

* test: miscellaneous minor test fixes for Go 1.17

* proc: resolve inlined calls when stepping out of runtime.breakpoint

Calls to runtime.Breakpoint are inlined in Go 1.17 when inlining is
enabled, resolve inlined calls in stepInstructionOut.

* proc: add support for debugCallV2 with regabi

This change adds support for the new debug call protocol which had to
change for the new register ABI introduced in Go 1.17.

Summary of changes:
- Abstracts over the debug call version depending on the Go version
  found in the binary.
- Uses R12 instead of RAX as the debug protocol register when the binary
  is from Go 1.17 or later.
- Creates a variable directly from the DWARF entry for function
  arguments to support passing arguments however the ABI expects.
- Computes a very conservative stack frame size for the call when
  injecting a call into a Go process whose version is >=1.17.

* TeamCity: enable tests on go-tip

* goversion: version compatibility bump

* TeamCity: fix go-tip builds on macOS/arm64
Co-authored-by: NMichael Anthony Knyszek <mknyszek@google.com>

Delete tests for old versions of Go that are no longer run, remove skip
from tests that seemingly work.

* TeamCity: change test matrix and test scripts

Changes test matrix to test:

* 1.13 through 1.16 on linux/amd64
* 1.15, 1.16 on windows/amd64
* 1.15 on linux/386

Also includes tests on go-tip for windows/amd64 and linux/amd64
(currently disabled, but can be turned on in a PR).

Changes test scripts to automatically select the latest patch version
of Go.

* CI: remove Travis-CI and Appveyor configuration

* add -json flag when running tests on TeamCity

* introduce TeamCity builds

* restore gdbserial constants for 386

Otherwise compilation fails.

* skip TestAttachRequest on Windows as it never finishes

* run tests on 1.16beta1
