* CHANGELOG.
*/
09292004 - Every API that can return a list of strings can now use a
callback mechanism if the application wants to do it's own
allocation or handling on a per-item basis. The guts of those
APIs that create string lists now use the callbacks themselves to
build the lists, too. The callback functionality goes all the way
down to the archivers and platform drivers where appropriate, which
cleans things up and simplifies some internal tasks very nicely.
09262004 - Did the same thing to FileHandles than I did to DirHandles, but
this triggered massive tweaking in physfs.c. A lot of code got
little cleanups, which was nice. Less malloc pressure, too, since
