The database format allows multiple lines to be stored in a single
record, to reduce the number of rows in the database. This change
allows reading such records, though there is not yet any code which
can write them. This change also adds a test that will benefit from
this record compression.

I copied the code from various dependencies in go-moremath
into a single 'internal/stats' package. That package is at the top
level of the repo because I expect to pull much of benchcmp
into an importable package.

For golang/go#14304.

The MySQL protocol requires 1-3 synchronous round-trips for every
INSERT statement; to reduce the overhead, we now batch up 900 label
INSERT statments at a time. This makes a massive difference;
TestQuery previously ran in 108s; with this change, it now runs in 5s.

We were also affected by golang/go#15606; since we now generate a new INSERT
statement for every record, we are sidestepping that issue.

The MySQL protocol and database/sql require several round-trips to
execute queries with placeholders. Setting interpolateParams will
cause the mysql client library to interpolate the arguments and issue
a single string query to the server, reducing the number of round
trips. See
