Vidar Holen f187382a0c Add bats support 
This is motivated by the fact that the popularity of bats is increasing
since the creation of bats-core/bats-core.

The code is a cherry-pick of koalaman/shellcheck/bats branch.

Fix koalaman/shellcheck#417.

Ng Zhi An 95a8cf93c9 Add check for ambiguous nullary test 
Given an input like `if [[ $(a) ]]; then ...`, this is a implicit `-n` test,
so it works like `if [[ -n $(a) ]]; then ...`. Users might confuse this for
a check for the exit code of the command a, which should be tested with:

    if a; then
        ...

We warn the user to be more explicity and specifity the `-n`.

Fixes #1416

Ng Zhi An 07f04e13ce Understand array variable declaration in read (fixes #679 fixes #1272) 
It used to only treat all trailing variables in read as varaible
declarings, but an array variable can be declared in other positions:

    read -a foo -r

foo is a declared variable, and multiple such variables can be declared.
