bug#10410: guile: uri module confused by domain names starting with numbers, ipv6 addresses

Hello

I have noticed that the (web uri) module does not handle domain names
that start with numbers:

scheme@(guile-user)> (string->uri "http://123.com";)
$1 = #f
scheme@(guile-user)> (build-uri 'http #:host "123.com")
web/uri.scm:85:6: In procedure build-uri:
web/uri.scm:85:6: Throw to key `uri-error' with args `("Expected valid
host: ~s" ("123.com"))'.


Also, `string->uri' does not handle ipv6 addresses:

scheme@(guile-user)> (string->uri "http://[2001:db8::1]";)
$2 = #f


Attached patch implements support for domain names that start with
numbers by correcting the
regular expressions used by `valid-host?' as well as some related tests.

`string->uri' requires similar changes to support the ipv6 address
literals.  I'm yet to found a very elegant way to do this though it is
easy enough to simply butcher `authority-pat'.
