Switch from urlparse() to urlsplit()

Hi ! This improves the middleware performance by roughly 1-5% (depending on the use case) by replacing urlib.parse.urlparse usage by the almost equivalent urlib.parse.urlsplit which perform 2x faster.

In [5]: %timeit urlparse("https://docs.djangoproject.com/en/4.1/;deprecated=true?q=1&e=2#123")
1.27 µs ± 5.06 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each)

In [6]: %timeit urlsplit("https://docs.djangoproject.com/en/4.1/;deprecated=true?q=1&e=2#123")
671 ns ± 4.21 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each)

This is really a slight improvement but since middleware are processed every request, small performance improvements adds up.

I saw Anthony's video too, I was idly wondering if there was any usage in the open source projects I maintain, thanks for tracking this down.
