Update test matrix to remove 1.18 and add 1.21, fix build scripts to
deal with the new format returned by:
https://golang.org/VERSION?m=text
which now has an extra second line with the time.
Windows/amd64 builds are not runnning because the current settings.kts
has an implicity requirement to property teamcity.build.systemDir which
does not exist on windows/amd64 agents.

The version of mingw was pinned to 10.2.0 because mingw 11 started
using DWARFv5, which wasn't supported by Go 1.17. We are now testing
only 1.18 and 1.19 and both support DWARFv5 correctly.
* go.mod: update golang.org/x/tools to v0.1.8
Fixes TestGeneratedDoc on go1.18
* TeamCity: bump test matrix
Add 1.18 to test matrix. Remove 1.15 from test matrix and from support range.
* proc,tests: update for regabi on arm64 and 386
Make sure that stacktrace registers always contain the PC register of
the current frame, even though the debug_frame rules might not specify
it on architectures that use a link register.
The PC register is needed to look up loclist entries for variable
evaluation.
* goversion: bump maximum supported Go version to 1.18
* proc: disable asyncpreempt on linux/arm64
Asyncpreempt on linux/arm64 can sometimes restart a sequence of
instructions which will make breakpoint appear to be hit twice in some
cases.
* 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: Michael Anthony Knyszek <mknyszek@google.com>
* 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
