interimap: fix handling of mod-sequence values greater or equal than 2 << 63.
SQLite processes every INTEGER values as a 8-byte signed integer, so we
need to manually do the conversion from/to uint64_t client-side if we
don't want to overflow or receive floats.

We could also do the same trick for local/remote UIDs, UIDVALITY and
UIDNEXT values to slim the database down at the expense of pre/post-
processing. (Values of SQLite's INTEGER class are 1, 2, 3, 4, 6, or 8
bytes signed integers depending on the manitudes, so we could save some
space for values ≥2³¹.) But that seems a little overkill.
