[PATCH v3] routines to generate JSON data

[git@jeffhostetler.com]

From: Jeff Hostetler <jeffhost@microsoft.com>

This is version 3 of my JSON data format routines.

This version addresses the variable name changes in [v2] and adds additional
test cases.  I also changed the BUG() calls to die() to help with testing.

The json-writer routines can be used generate structured data in a JSON-like
format.  I say "JSON-like" because we don't enforce the Unicode/UTF-8
requirement [3,4] on string values.  This was discussed on the mailing list
in the [v1] and [v2] threads, but to summarize here: Git doesn't know if
various fields, such as Unix pathnames and author names, are Unicode or just
8-bit character data, so Git would not know how to properly encode such
fields and the consumer of such output would not know these strings were
encoded (once or twice).  So, until we have a pressing need to generate
proper Unicode data, we avoid it for now.

The initial use for the json-writer routines is for generating telemetry data
for executed Git commands.  Later, we might want to use them in other commands
such as status.
