Add --blocklist-file option (#2097)

Update Item to hold a `clang::SourceLocation` and use this to allow
blocklisting based on filename.

The existing code has a special case that always maps <stdint.h> integer
types to corresponding Rust integer types, even if the C types are
blocklisted.  To match this special case behaviour, also treat these
C <stdint.h> types as being eligible for derived Copy/Clone/Debug
traits.

Fixes #2096
