name; this is a higher performance alternative to the generic php() SQL
function. (saves parsing the additional function call in the SQL and a call to
zend_is_callable on each function invocation).
Add test for sqlite_create_function().
Fixup proto for sqlite_create_aggregate().
Tweak package file and speling in header file.
Add a test-case for that process.
When encoding binary data, we mark the string with \x01 as its first character.
When returning data via sqlite_fetch_array(), if the first character is \x01,
then we decode the encoding. This behaviour can be turned off by the optional
last parameter to sqlite_fetch_array(), for compatibility with databases
created with other applications.
