drh 9291372094 Add interfaces sqlite3_uri_boolean() and sqlite3_uri_int64() which are 
wrappers around sqlite3_uri_parameter() combined with internal routines for
converting strings to booleans and 64-bit integers.

drh 8c24a369a5 Tweaks to the way multiplexSubOpen() works, for backwards compatibility.

on the multiplexWrite() method of the multiplexor.

drh e7d9f13d99 The xTruncate method for the multiplexor now changes surplus overflow 
files to zero-length by default.  Or if the "truncate" query parameter 
is used, it actually deletes the surplus overflow files.  This allows
VACUUM to shrink the database again.

drh 78c0eafb35 Make sure the chunksize in test_multiplex does not cause the pending byte 
to fall near the end of a chunk.  Adjust the chunksize upward as necessary
to prevent this.

And assume all but the last overflow file is the size of the chunk size.

drh c7f946297a Change the SQLITE_EXTRA_INIT routine to take a single argument which is a 
pointer to a string.  Call SQLITE_EXTRA_INIT with a NULL argument.
Fixes to multiplexor to treat the VFS properly in corner cases.  Fix the
initialization of multiplex3.test.
