Fixes#4802. The Go HTTP server has a global panic handler for requests, so it was not as severe as first thought.
This fix can still panic, since we try to send a `500` response - if that happens, the Go HTTP server will terminate the connection. Otherwise, the client will get a 200 response, which we should avoid. I'm sort of torn on whether it's even necessary to include this fix, instead of just letting the HTTP server deal with it.
* blockchain/v2: fix excessive CPU usage due to spinning on closed channels (#4761)
The event loop uses a `select` on multiple channels. However, reading from a closed channel in Go always yields the channel's zero value. The processor and scheduler close their channels when done, and since these channels are always ready to receive, the event loop keeps spinning on them.
This changes `routine.terminate()` to not close the channel, and also removes `stopDemux` and instead uses `events` channel closure to signal event loop termination.
Fixes#4687.
* blockchain/v2: respect fast_sync option (#4772)
Not thoroughly tested, but seems to work. Will do further testing as this is integrated with state sync.
Fixes#4688.
* lite: fix HTTP provider error handling
Fixes#4739, kind of. See #4740 for the proper fix.

Reduce the number of targets and make the buildsystem more
flexible by parsing the TENDERMINT_BUILD_OPTIONS command
line variable (a-la Debian, inspired by dpkg-buildpackage's
DEB_BUILD_OPTIONS), e.g:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb'
replaces the old:
$ make install_c
Options can be mix&match'd, e.g.:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb race nostrip'
Three options are available:
- nostrip: don't strip debugging symbols nor DWARF tables.
- cleveldb: use cleveldb as db backend instead of goleveldb;
it switches on the CGO_ENABLED Go environment variale.
- race: pass -race to go build and enable data race detection.
This changeset is a port of gaia pull request: cosmos/gaia#363.

- Move core stateless validation of the Header type to a ValidateBasic method.
- Call header.ValidateBasic during a SignedHeader validation.
- Call header.ValidateBasic during a PhantomValidatorEvidence validation.
- Call header.ValidateBasic during a LunaticValidatorEvidence validation.
lite tests are skipped since the package is deprecated, no need to waste time on it

Followup from #4588. Allow the first `SaveBlock()` call in an empty block store to be at any height, to start from a truncated block history. Subsequent `SaveBlock()` calls must be for contiguous blocks.

The service logging can be a bit unclear. For example, with state sync it would log:
```
I[2020-04-20|08:40:47.366] Starting StateSync module=statesync impl=Reactor
I[2020-04-20|08:40:47.834] Starting state sync module=statesync
```
Where the first message is the reactor service startup, and the second message is the start of the actual state sync process. This clarifies the first message by changing it to `Starting StateSync service`.

I believe this is appropriate. Anything else that needs to be updated?

## Description
The minor release process is changing in order to not have major release changes sitting in the pull request tab.
This changes from taking master and releasing from master to creating a branch that you cherry-pick commits into.
There are two options on labeling which pull requests to include in a minor release:
1. Use the label `R:minor` to know which pull requests to include then remove the label when those pull requests have been included in a release.
2. Create an Issue where pull request numbers are added. then the issue is closed when the release is done.
this process should be followed after 0.33.3

Fixes an issue reported in https://github.com/tendermint/tendermint/issues/4595#issuecomment-612667441.
Not sure if this is sufficient to fully remove the reactor, but it fixes the immediate problem.

How to use it:
```
$ . <(tendermint completion)
```
Note that the completion command does not show up in the help screen,
though it comes with its own --help option.
This is a port of the feature provided by cosmos-sdk.
