This PR makes Tendermint Architectural Overview not visible mainly because there are todos and it duplicates some information.

## Description

Fix a bunch of old and broken links in markdown files.

Possibly fixes #4842. I'm not familiar with the doc generation pipeline, but other images under `imgs/` seem to work so just cargo-culting it.

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.

Closes #4202

- nobody's supporting them
- users who want to try TM should use pre-build binaries
- devs should be able to install using git clone (or use Vagrant)
- validators don't use them (my guess)

Why:
original fork is abandoned and not supported anymore.

Changes:
- LevelDB 1.19 (LevelDB and Snappy are both compiled and linked statically, so while you will not need them installed on your target machine, you should have a roughly compatible version of libstdc++.)
- snappy and lz4 libs included by default
