Amit fd34511314 Switch to Go 1.23 and fix CI failures
Some new upcoming changes require us to use Go 1.23. However, if we switch to Go 1.23 some
new linter errors are showing up. This commit fixes most of the errors and adds an
exclusion for integer overflow errors.

Hamza El-Saawy 3c9576c934 Update go1.21 and CI (#315)
* Update to go 1.21

Use `atomic.Bool` stdlib instead of including our own.

Include `tools\mkwinsyscall` updates from go-winio/283 to switch to
`syscallN`.
Note: removed `// TODO` about `print`/`ln`, since the latter adds spaces
between args when printing, which is undesired.

Also update CI to run steps on windows-2022 instead of windows-2019,
similar to our hcsshim CI.

Hamza El-Saawy 9f0d5dc7d2 Switch from sycall to windows (#295)
Where ever possible, use `golang.org/x/sys/windows` instead of `syscall`
(which has been deprecated since go1.11).

Using `windows.LocalFree` requires using `unsafe.Pointer`, which ensures
that the Go garbage collector does not try to free memory pre-maturely
if it was previously declared as a pointer.

Since `syscall.Handle` is part of API for `vhd` package, it was left
unchanged.

For security descriptor functions, switch to using
`windows.SECURITY_DESCRIPTOR` to avoid unnecessary byte manipulation and
panics due to missing input validation and error checking.

Hamza El-Saawy 19a9f656e1 Update tests; run fuzzing (#294)
Run fuzzing tests in CI.

Use race detector when running tests.

Add missing `t.Helper()` calls.

Update test helpers in `pkg/bindfilter` to use `RtlGetNtVersionNumbers`
instead of reading registry, and skip tests if not running as admin.

Gabriel dd5de6900b Add some basic bind filter functions (#274)
* Add some basic bind filter functions

This change adds the ability to mount a a single folder or a volume
inside another folder, using the bind filter API.

While the API allows mounting multiple sources inside a single mount
point, acting as an overlay, we disable this functionality in the ApplyFileBinding
function.
