This is as per the RFC, which says the scheme and path can never be
missing, while the path can be empty. file: [375c07c449] check-in: [3e455c4839] user: js, branch: trunk, size: 10704 [annotate] [blame] [check-ins using] [diff]

The scheme does not allow percent encoding. file: [800b8aa913] check-in: [13ead1212f] user: js, branch: trunk, size: 10413 [annotate] [blame] [check-ins using] [diff]

With a dictionary the order is lost and keys cannot exist more than
once. file: [a21b779d5d] check-in: [bd6dd6dd00] user: js, branch: trunk, size: 10520 [annotate] [blame] [check-ins using] [diff]

These were unavailable in the immutable class, but available in the
mutable subclass. However, Clang 3.4 does not support this. file: [5ffb066ab5] check-in: [dae363ef82] user: js, branch: trunk, size: 5988 [annotate] [blame] [check-ins using] [diff]

This allows retrieving it how it was originally stored, which is useful
for example for query strings, as these often URL-encode allowed
characters in order to allow pairs of the form foo=bar&bar=qux. file: [b9f96c6e08] check-in: [a15b403a11] user: js, branch: trunk, size: 4696 [annotate] [blame] [check-ins using] [diff]

This also means the parameters go away and get folded into the path. file: [f6b587c9bc] check-in: [5f7305c659] user: js, branch: trunk, size: 2452 [annotate] [blame] [check-ins using] [diff]

This removes the special handling dependent on the scheme. file: [514dff27bb] check-in: [0f995db06d] user: js, branch: trunk, size: 2086 [annotate] [blame] [check-ins using] [diff]

Instead, explicitly declare them, as OF_ASSUME_NONNULL_{BEGIN,END} does
not apply to implicit return types. This means that after this commit,
all init methods have a nonnull return type, as they should have. file: [aa49ba568a] check-in: [2f4e0df8be] user: js, branch: trunk, size: 2016 [annotate] [blame] [check-ins using] [diff]
