Add support for basic shflags semantics
...
The shflags command-line flags library creates variables at runtime
with a few well-defined functions. This causes shellcheck to spit out
lots of warnings about unassigned variables, as well as miss warnings
about unused flag variables.
We can address this with two parts:
1. Pretend that the shflags global variables are predefined like other
shell variables so that shellcheck doesn't expect users to set them.
2. Treat DEFINE_string, DEFINE_int, etc. as new commands that create
variables, similar to the existing read, local, mapfile, etc.
Part 1 can theoretically be addresssed without this by following sourced
files, but that doesn't help if people are otherwise not following
external sources.
The new behavior is on by default, similar to automatic bats test
behavior.

SC2250: New optional check for braces around variable references
...
Always using braces makes it harder to accidentally change a variable by
pasting other text next to it, but the warning is off by default because
it's definitely a style preference. Omit special and positional
variables from the check because appending additional characters to them
already doesn't change parsing.

Track whether braces were present in T_DollarBraced
...
References of the form $var and ${var} both map to the same structure in
the AST, which prevents any later analysis functions from distinguishing
them. In preparation for adding checks that need this info, add a Bool
to T_DollarBraced that tracks whether the braces were seen at parsing
time and update all references so that this change is a no-op.

Add option to look for sources in alternate root paths

Add a new optional flag "-r|--root ROOTPATHS", where ROOTPATHS is a
colon separated list of paths, that will look for external sources in
alternate roots.
This is particular useful when the run-time environment does not fully
match the development environment. The #shellcheck source=file directive
is useful, but has its limitations in certain scenarios. Also, in many
cases the directive could be removed from scripts when the root flag is
used.

#!/bin/bash
source /etc/foo/config
Example usage where etc/foo/config exists in skel/foo:
# shellcheck -x -r skel/foo:skel/core example.bash

Realign virtual tabs when applying fix
...
Fix an off-by-one error, in the case that is commented `should never happen`.
It happens when the end of a range is the at the end of a line.
In that case we should update the real column count (probably just by +1)
instead of returning it.
I modified makeNonVirtual to use a helper, realign, that works on
Ranged. That way we can share the code to realign a PositionedComment
and also a Replacement.

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
