[Qemu-devel] [PATCH v3 41/58] json: Replace %I64d, %I64u by %PRId64, %PRIu64

[Markus Armbruster]

Support for %I64d got added in commit 2c0d4b36e7f "json: fix PRId64 on
Win32".  We had to hard-code I64d because we used the lexer's finite
state machine to check interpolations.  No more, so clean this up.

Additional conversion specifications would be easy enough to implement
when needed.
