Description:
------------
Telling SQLite to open a file of NULL or "" causes it to 
think for a while and then report that the database is 
locked.

The patch at:

http://www.trachtenberg.com/patches/sqlite_open.txt

Makes SQLite return false and provides an error message. 
(BTW, is strcmp(filename, "") the best way to do this?

Reproduce code:
---------------
sqlite_open("");
sqlite_open(NULL);

Expected result:
----------------
Faster reply, better error message.

Actual result:
--------------
PHP Warning:  sqlite_query(): database is locked

Can't you just test whether the filename_len is higher than 0 ??

Yea. Here's an updated version at the same URL.
