* Switch remaining old-style PHP 5.4 `Array(...)` declarations to `[...]`
* Update variable names getting rid hungarian notation prefixes (e.g.
`str_`, `i_`, etc).
* Allow cluster seeds to be passed on the command-line instead of soley
relying on either a node environment variable or our
tests/nodes/nodemap file. This should make it easier to run ad-hoc
cluster tests by specifying just a single seed.
* Add some diagnostics for when we can't find a suitable cluster to run
our tests against indicating exactly where we looked for the env var
and node file.
* Refactor RedisArray tests to use our newer TestSuite assertions.
* Allow `RedisArray` ports to be specified on the command-line as well.
* Various formatting fixes.
* More robust KeyDB detection.
In the `package.xml` file we have `arrays.md` instead of `array.md`: that breaks the compilation with pecl:
ERROR: file /path/to/phpredis/arrays.md does not exist
