f6ba500d6b 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.

Addresses #1597

64c9c83cc8 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.

aa3b709b5d 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.

This ensures that the parser and other places that refer to special
variables can use the same list.

50af8aba29 Add json1 format that ignores tabs 
The new json1 format works just like json except that it treats tabs as
single characters instead of 8-character tabstops.

The main use case is to allow editors to pass -fjson1 so that they can
consume the json output in a character-oriented way without breaking
backwards compatibility.

Also addresses #1048.
