/**
* URIs are essentially structured names for things -- anything. This interface
* provides accessors to get the most basic components of an URI.
* If you need to change some parts of the URI use nsIURIMutator.
* Subclasses, including nsIURL, impose greater structure on the URI.
*
* This interface follows Tim Berners-Lee's URI spec (RFC3986) [1], where the
* basic URI components are defined as such:
* <pre>
* \ / \ / \ / \ /\ / \ / \ /
* - --------------- ------ -------- ------- --- -
* | | | | | | |
* | | | | FilePath Query Ref
* | | | Port \ /
* | | Host / ------------
* | UserPass / |
* Scheme / Path
* \ /
* --------------------------------
* |
* PrePath
* </pre>
* The definition of the URI components has been extended to allow for
* internationalized domain names [2] and the more generic IRI structure [3].

* nsIURI - interface for an uniform resource identifier w/ i18n support.

* AUTF8String attributes may contain unescaped UTF-8 characters.
* Consumers should be careful to escape the UTF-8 strings as necessary, but
* should always try to "display" the UTF-8 version as provided by this
* interface.
*
* AUTF8String attributes may also contain escaped characters.
*
* Unescaping URI segments is unadvised unless there is intimate
* knowledge of the underlying charset or there is no plan to display (or
* otherwise enforce a charset on) the resulting URI substring.
*
* The correct way to create an nsIURI from a string is via
* nsIIOService.newURI.
*
* NOTE: nsBinaryInputStream::ReadObject contains a hackaround to intercept the
* old (pre-gecko6) nsIURI IID and swap in the current IID instead, in order
* for sessionstore to work after an upgrade. If this IID is revved further,
* we will need to add additional checks there for all intermediate IIDs, until
* ContentPrincipal is fixed to serialize its URIs as nsISupports (bug 662693).
