New test added in CL 14611045 causes a deadlock when
running the tests with -cpu=n,n because the fakedb
driver always waits when opening a new connection after
running TestConnectionLeak.  Reset its state after.

Please note the slight rewording for append: The spec now
requires that append reuses the underlying array if it is
sufficiently large. Per majority sentiment.

This is technically a language change but the current
implementation always worked this way.

Fixes #5818.
Fixes #5180.

CL 10726044 introduced a race condition which causes connections
to be leaked under certain circumstances. If SetMaxOpenConns is
used, the application eventually deadlocks. Otherwise, the number
of open connections just keep growing indefinitely.

Fixes #6593

Add a check at the end of every test to make sure
there are no leaked connections after running a test.

Avoid incorrectly decrementing the number of open connections
when the driver connection ends up it a bad state (numOpen was
decremented twice).

Prevent leaking a Rows struct (which ends up leaking a
connection) in Row.Scan() when a *RawBytes destination is
improperly used.

Close the Rows struct in TestRowsColumns.

Fixes #6595.

The preamble may want to #define some special symbols
and then #include <sys/types.h> itself. The builtin prolog
also #includes <sys/types.h>, which would break such a
preamble (because the second #include will be a no-op).

The use of sys/types.h in the builtin prolog is new since Go 1.1,
so this should preserve the semantics of more existing cgo
code than we would otherwise.

It also fixes src/pkg/syscall/mkall.sh's use of go tool cgo -godefs
on some Linux systems.

Thanks to fullung@ for identifying the problem.

Fixes #6558.

At the moment, godoc expands the example in the link, but in
