[PATCH v3 2/4] quote: add quote_path() flag to ignore config

[Justin Tobler <jltobler@gmail.com>]

The `quote_path()` function invokes `quote_c_style_counted()` to handle
quoting. This means the output `quote_path()` is ultimately affected by
`core.quotePath` configuration. In a subsequent commit, `quote_path()`
will be used in a scenario where the output should remain consistent
regardless of the current configuration.

Introduce the `QUOTE_PATH_IGNORE_CONFIG` flag for `quote_path()`which
when set instructs the underlying `quote_c_style_counted()` to also
ignore the `core.quotePath` configuration when executed.
