/**
* Parses URI.
*
* This is a general URL parser. It's typically used for HTTP. Support
* for the bonus syntax needed by SIP is provided. The whirlwhind tour
* of the URI rabbit hole is as follows:
*
* /foo.html
* //justine.local/foo.html
* http://justine.local/foo.html
* http://bettersearchengine.local/search.cgi?q=my%20query
* file:///etc/passwd
* gs://bucket/object.txt
* zip:///usr/share/zoneinfo/GMT
* sip:127.0.0.1:5060;lr
* sip:+12125650666@gateway.example
* sip:bob%20barker:priceisright@[dead:beef::666]:5060;isup-oli=00
* data:video/mpeg;base64,gigabytesofhex
*
* This parser operates on slices rather than C strings. It performs
* slicing and validation only. Operations like turning "%20"→" " or
* "80"→80 and perfect hashing can be done later, if needed.
*
* The Uri object is owned by the caller; it has a lifecycle like the
* following:
*
* struct Uri uri;
* memset(&uri, 0, sizeof(uri));
*
* uriparse(&uri, s1, strlen(s1));
* CHECK_EQ(kUriSchemeHttp, urischeme(uri->scheme, s1));
*
* uriparse(&uri, s2, strlen(s2));
* printf("host = %`.*s\n", uri->host.n, s2 + uri->host.i);
*
* Inner arrays may be granted memory by the caller. The uri->𝐴.i field
* is cleared at the mark of this function. No more than uri->𝐴.n items
* can be inserted. If we need more than that, then ENOMEM is returned
* rather than dynamically extending uri->𝐴.p. However, if uri->𝐴.n==0,
* we assume caller doesn't care about uri->𝐴 and its data is discarded.
*
* @param uri is owned by caller
* @param p is caller-owned uri string; won't copy/alias/mutate
* @return 0 on success, or -1 w/ errno
* @see RFC2396: Uniform Resource Identifiers (URI): Generic Syntax
* @see RFC3261: SIP: Session Initiation Protocol
