Modified (quite a bit!) patch from John Coggeshall.
It compiles, but it otherwise untested.
session.save_path == path to actual database file for the session.
eg: session.save_path=/tmp/mysite-session.db
Cleaner approach for setting THREADSAFE and NDEBUG for bundled libsqlite.
Tested with: static, shared and shared with separate build roots under a
non-zts build only.
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.
function with a similar name.
Change sqlite_query() to use the same mechanism as the unbuffered query; this
moves the bulk of the memory allocations into the ZE memory manager, and will
hopefully be more efficient and less at risk of leaks.
