host matching: handle wildcards with non-standard port (#10)
In OpenSSH, wildcard host pattern entries in a known_hosts file can match
hosts regardless of their port number. However, x/crypto/ssh/knownhosts does
not follow this behavior, instead requiring strict port equality; see bug
https://github.com/golang/go/issues/52056 for background.
This commit implements a workaround in skeema/knownhosts, which is enabled
when using the NewDB constructor. Conceptually, the workaround works like
this:
* At constructor time, when re-reading the known_hosts file (originally to
look for @cert-authority lines), also look for lines that have wildcards
in the host pattern and no port number specified. Track these lines in a
new field of the HostKeyDB struct for later use.
* When a host key callback returns no matches (KeyError with empty Want slice)
and the host had a nonstandard (non-22) port number, try the callback again,
this time manipulating the host arg to be on port 22.
* If this second call returned nil error, that means the host key now matched
a known_hosts entry on port 22, so consider the host as known.
* If this second call returned a KeyError with non-empty Want slice, filter
down the resulting keys to only correspond to lines with known wildcards,
using the preprocessed information from the first step. This ensures we
aren't incorrectly returning non-wildcard entries among the Want slice.
The implementation for the latter 3 bullets gets embedded directly in the
host key callback returned by HostKeyDB.HostKeyCallback, by way of some
nested callback wrapping. This only happens if the first bullet actually
found at least one wildcard in the file.

Merge pull request #9 from skeema/certs-backwards-compat
Backwards-compatible support for @cert-authority, implemented in a new HostKeyDB type, created with constructor NewDB.

Minor adjustments based on initial PR feedback
* Add new exported method HostKeyCallback.ToDB, to provide a mechanism for
callers who want to conditionally enable or disable CA support, while still
using a *HostKeyDB for both cases.
* Clarify many doc string comments.
* Add new exported function WriteKnownHostCA for writing a @cert-authority
line to a known_hosts file. Previously this logic was in a test helper, but
it could be useful to others, so let's export it outside of the tests.

certs: reimplement previous commit to maintain backwards compat
The previous commit d314bf36 added support for @cert-authority lines, but
technically broke backwards compatibility due to changing the return type of
one exported method. This commit adjusts that previous commit's new logic to
restore backwards compatibility, and makes additional changes as follows:
* Introduce new exported type HostKeyDB, which handles @cert-authority lines
correctly and is returned by NewDB; old exported type HostKeyCallback (which
is returned by New) omits that handling. Git-specific use-cases can likely
remain with using New, since Git forges typically don't support CAs. Non-Git
use-cases, such as general-purpose SSH clients, should consider switching to
NewDB to get the CA logic.
* When NewDB re-reads the known_hosts files to implement the CA support, it
only re-reads each file a single time (vs potentially multiple times at
callback execution time in d314bf36), and it reads using buffered IO similar
to x/crypto/ssh/knownhosts.
* This package's PublicKey struct now exports its Cert boolean field, vs
keeping it private in d314bf36.
* Refactor the RSA-to-algo expansion logic to simplify its handling in the CA
situation.
* Add test coverage for all new behaviors and @cert-authority logic.

ci: bump GOVERSION and fix golint
GitHub Actions was configured to use Go 1.17, which is quite old. This commit
bumps it to Go 1.21, which is the older of the two currently-supported Go
versions.
This commit also adjusts the command-line for installing `golint` to be
compatible with more recent Go versions.
Keeping go.mod at 1.17 for now though, unless/until we actually need newer Go
language features. Since github.com/skeema/knownhosts is imported by a lot of
other Go packages, we don't want to force increases to that listed version
unnecessarily.

HostKeyAlgorithms: ensure result never contains duplicates
Currently the behavior of HostKeyAlgorithms never contains duplicates, only by
virtue of golang.org/x/crypto/ssh/knownhosts exposing a maximum of one key per
algorithm in its KeyError.Want slice.
However, that upstream behavior could theoretically change in the future,
especially since golang.org/x/crypto is versioned as a pre-v1 module, and the
one-key-per-type behavior is only documented as a comment (e.g. not part of
any type or function signature).
This commit makes our HostKeyAlgorithms function more robust / future-proof
by ensuring that its result does not contain duplicates, regardless of
upstream behavior.
This means if https://github.com/golang/go/issues/28870 is solved (for example
by https://github.com/golang/crypto/pull/254), there should not be any harm to
our behavior here in github.com/skeema/knownhosts.

tests: memoize the generated test known_hosts file
Previously, several test functions each wrote their own test known_hosts file,
generating different random keys each time. This is slow and CPU-intensive.
This commit changes the test logic to generate random keys once per overall
test process, and re-use those test known_hosts contents across multiple test
functions.

Add several new exported functions and methods
* Add new method HostKeyCallback.HostKeys() for looking up the public keys
for a given host; result is sorted based on known_hosts filename and line
* HostKeyCallback.HostKeyAlgorithms() now uses HostKeyCallback.HostKeys(),
so its result now has a well-defined sort order
* New convenience functions IsHostKeyChanged(), IsHostUnknown(), and
WriteKnownHost(). Ideally this package now provides enough functionality
that it can cover the use-cases of golang.org/x/crypto/ssh/knownhosts
(it should be sufficient to import github.com/skeema/knownhosts alone
without ever needing to also import golang.org/x/crypto/ssh/knownhosts)
