[SVN-4896] Review crash-safety of new temporary files

• Type: Improvement

Description

Audit the new code and verify that all temporary files are created in a crash-safe way; that is: in such a way that if libsvn_wc is SIGKILL'd during an operation (during or after hydrating and before dehydrating), then the temporary file will be deleted by svn at some point in the future.

E.g., if libsvn_wc is killled halfway through hydrating a 10GB file, make sure the 5GB tempfile won't just be left behind forever, but will be deleted by svn later.
