431618cef6 lite2: remove auto update (#4535)
We first introduced auto-update as a separate struct AutoClient, which
was wrapping Client and calling Update periodically.

// AutoClient can auto update itself by fetching headers every N seconds.
type AutoClient struct {
    base         *Client
    updatePeriod time.Duration
    quit         chan struct{}

    trustedHeaders chan *types.SignedHeader
    errs           chan error
}

// NewAutoClient creates a new client and starts a polling goroutine.
func NewAutoClient(base *Client, updatePeriod time.Duration) *AutoClient {
    c := &AutoClient{
        base:           base,
        updatePeriod:   updatePeriod,
        quit:           make(chan struct{}),
        trustedHeaders: make(chan *types.SignedHeader),
        errs:           make(chan error),
    }
    go c.autoUpdate()
    return c
}

// TrustedHeaders returns a channel onto which new trusted headers are posted.
func (c *AutoClient) TrustedHeaders() <-chan *types.SignedHeader {
    return c.trustedHeaders
}

// Err returns a channel onto which errors are posted.
func (c *AutoClient) Errs() <-chan error {
    return c.errs
}

// Stop stops the client.
func (c *AutoClient) Stop() {
    close(c.quit)
}

func (c *AutoClient) autoUpdate() {
    ticker := time.NewTicker(c.updatePeriod)
    defer ticker.Stop()

    for {
        select {
        case <-ticker.C:
            lastTrustedHeight, err := c.base.LastTrustedHeight()
            if err != nil {
                c.errs <- err
                continue
            }

            if lastTrustedHeight == -1 {
                // no headers yet => wait
                continue
            }

            newTrustedHeader, err := c.base.Update(time.Now())
            if err != nil {
                c.errs <- err
                continue
            }

            if newTrustedHeader != nil {
                 c.trustedHeaders <- newTrustedHeader
            }
        case <-c.quit:
            return
        }
    }
}

Later we merged it into the Client itself with the assumption that most clients will want it.

But now I am not sure. Neither IBC nor cosmos/relayer are using it. It increases complexity (Start/Stop methods).

That said, I think it makes sense to remove it until we see a need for it (until we better understand usage behavior). We can always introduce it later 😅. Maybe in the form of AutoClient.

6daea31f50 lite2: remove expiration checks on functions that don't require them (#4477)
closes: #4455

Verifying backwards checks that the trustedHeader hasn't expired both before and after the loop in case of verifying many headers (a longer operation), but not during the loop itself.

TrustedHeader() no longer checks whether the header saved in the store has expired.

Tests have been updated to reflect the changes

## Commits:

* verify headers backwards out of trust period

* removed expiration check in trusted header func

* modified tests to reflect changes

* wrote new tests for backwards verification

* modified TrustedHeader and TrustedValSet functions

* condensed test functions

* condensed test functions further

* fix build error

* update doc

* add comments

* remove unnecessary declaration

* extract latestHeight check into a separate func

c4f7256766 lite2: store current validator set (#4472)
Before we were storing trustedHeader (height=1) and trustedNextVals
(height=2).

After this change, we will be storing trustedHeader (height=1) and
trustedVals (height=1). This a) simplifies the code b) fixes #4399
inconsistent pairing issue c) gives a relayer access to the current
validator set #4470.

The only downside is more jumps during bisection. If validator set
changes between trustedHeader and the next header (by 2/3 or more), the
light client will be forced to download the next header and check that
2/3+ signed the transition. But we don't expect validator set change too
much and too often, so it's an acceptable compromise.

Closes #4470 and #4399

4bfec797e8 cli: debug sub-command (#4227)
## Issue

Implement a new subcommand: tendermint debug. This subcommand itself has two subcommands:

    $ tendermint debug kill <pid> </path/to/out.zip> --home=</path/to/app.d>

Writes debug info into a compressed archive. The archive will contain the following:

├── config.toml
├── consensus_state.json
├── net_info.json
├── stacktrace.out
├── status.json
└── wal

The Tendermint process will be killed.

    $ tendermint debug dump </path/to/out> --home=</path/to/app.d>

This command will perform similar to kill except it only polls the node and dumps debugging data every frequency seconds to a compressed archive under a given destination directory. Each archive will contain:

├── consensus_state.json
├── goroutine.out
├── heap.out
├── net_info.json
├── status.json
└── wal

Note:

    goroutine.out and heap.out will only be written if a profile address is provided and is operational.
    This command is blocking and will log any error.

replaces: #3327
closes: #3249

## Commits:

* Implement debug tool command stubs

* Implement net getters and zip logic

* Update zip dir API and add home flag

* Add simple godocs for kill aux functions
