* Add lint and go generate stages to CI
Add CI step to verify `go generate` was run on repo.
Add linter stage to CI along with linter config file,
`.golangci.yml`.
Will likely prefer revive over static-check.
Updated README Contributing section on linting requirements.
Added sequence ordering to make sure lint and go generate stages run
before tests and build.
This way, build and tests are not run on code that could potentially:
1. not build due to `gofmt` issues;
2. contain bugs;
3. have to be re-submitted after issues are fixed; or
4. contain outdated Win32 syscall or other auto-generated files.

* Fixed linter issues
Code changes to satisfy linters:
- Ran `gofmt -s -w` on repo.
- Broke up long lines.
- When possible, changed names with incorrect initialism formatting
- Added exceptions for exported variables.
- Added exceptions for ALL_CAPS_WITH_UNDERSCORES code.
- Switched to using `windows` or `syscall` definitions if possible;
especially if some constants were unused.
- Added `_ =` to satisfy error linter, and acknowledge that errors are
being ignored.
- Switched to using `errors.Is` and `As` in places, elsewhere added
exceptions if error value was known to be `syscall.Errno`.
- Removed bare returns.
- Prevented variables from being overshadowed in certain places
(ignoring cases of overshadowing `err`).
- Renamed variables and functions (eg, `len`, `eventMetadata.bytes`) to
prevent shadowing pre-built functions and imported pacakges.
- Removed unused method receivers.
- Added exceptions to certain unused (unexported) constants and
functions.
- Deleted unused `once` from `pkg/etw.providerMap`.
- Renamed `noop.go` files to `main_other.go` or `doc.go`, to better fit
style recommendations.
- Added exceptions for non-secure use of SHA1 and weak crypto
libraries.
- Replaced `ioutil` with `io` and `os` (and `t.TempDir` in tests).
- Added fully exhaustive checks for `switch` statements in `pkg/etw`.
- Defined constant strings for `tools/mkwinsyscall`.
- Removed unnecessary conversions.
- Made sure `context.Cancel` was called.
Additionally, added `//go:build windows" constraints on files with
unexported code, since linter will complain about unused code on
non-Windows platforms.
Added a stub `main() {}` for `mkwinsyscall` for non-Windows builds, just in
case `//go:generate` directives are added to OS-agnostic files.

* PR: spelling, constants, fuzzing
Moved HVSocket fuzzing tests to separate file with go 1.18 build
constraint.

This may be a theoretical situation, but the tar headers may contain
both the old and new headers, in which case we would be decoding
both.
This patch rewrites the function to try the new headers first, and
return early if found, then fall back to trying the old headers.

Separates out Security Descriptor (SDDL), Extended Attribute (EA) and Reparse tag encoding
code into individual functions so that those functions can be reused in other code (like
CimFS layer writing)

A recent OS change altered how sparse files are represented in backup
streams. This caused backuptar to no longer work with certain files. The
specific behavior that changed is as follows:
- Empty sparse files (size = 0), previously did not have any data or
sparse block streams in the backup stream. Now, they will have a
data stream with size = 0, and no sparse block streams.
- Sparse files with a single allocated range (e.g. a normal file that
has the sparse attribute set) previously would not show as sparse in
the backup stream. Now, they will show as sparse.
The old backuptar behavior assumed that if the sparse flag was set on
the data stream, then there would always be a set of sparse blocks
following. These changes break this assumption, and so require special
handling.
It is unsupported to have a data stream, marked sparse, that contains
file content AND a series of sparse block streams following. As far as
I can tell this is not a valid case for backup streams.
This change also cleans up some code and error messages, and expands on
the test coverage for backuptar.

We also get pre-defined constants instead of carrying our own copies.
However, this changes the public API winio.FileBasicInfo from using
syscall.Filetime to using windows.Filetime, as visible in
backuptar/tar.go.

Since Go 1.6, archive/tar has gained public support for custom PAX
Records, so there's no need to maintain a fork of this library anymore.
We do end up with a fork of the PAX timestamp parsing/formatting
functions, but they are much less likely to change.

This removes the MSWINDOWS.* time fields and uses PAX times directly. I
didn't previously realize that PAX times could be negative, which
eliminates the need to store Windows times in a different format.
This also uses the LIBARCHIVE.creationtime field for creation times to
match OS X behavior.
