<li>Report the name of specific [CHECK] constraints that fail.
<li>In the command-line shell, use popen() instead of fopen() if the first
character of the argument to the ".output" command is "|".
<li>Make use of OVERLAPPED in the windows [VFS] to avoid some system calls
and thereby obtain a performance improvement.
<li>More aggressive optimization of the AND operator when one side or the
other is always false.
<li>Add the [SQLITE_RTREE_INT_ONLY] compile-time option to force the
[rtree | R*Tree Extension Module] to use integer instead of
floating point values for both storage and computation.
<li>Enhance the [PRAGMA integrity_check] command to use much less memory when
processing multi-gigabyte databases.
<li>New interfaces added to the test_quota.c add-on module.
<li>Added the ".trace" dot-command to the command-line shell.
