Comment (by joemcgill):

 [attachment:"40175.4.diff"] is an iteration on [attachment:"40175.3.diff"]
 which includes the following changes:

 - Removes `application/octet-stream` from the list of supported mime types
 for `exe` files.
 - Rename the filter in `wp_get_file_types()` from `wp_mimes` to
 `wp_file_types`.
 - Rename `wp_maybe_rename_file` to `wp_maybe_fix_image_extension()`.
 - Fixes some bugs when filtering the list of mime types due to the early
 `wp_check_filetype()` check or improper extension renaming.
 - Adds a unit test for GPX files, which also serves as a test for the
 `wp_file_types` filter.

 **TODO:**

 - Implement a deprecation strategy for `wp_get_mime_types()`.
 - Decide how to handle unit tests that fail based on underlying server
 architecture.
