Some applications only support ipv4 so add ipv4only option
to host and hostport datatypes so that for thos applications
that when an IP address is specified only and ipv4 ip address
gets accepted.
The previous versiono of ipaddrport validator only worked for ipv4
due to disallowing colons (:) in ip address which obvious fails for
ipv6. We now instead allow either ipv4 address or an ipv6 address of
the form [<ipv6address>]:port
Some files and pointers to files are not safe to remove without a replacement
file and config pointing to the file. For instance for uhttpd application in
the works, removing the certificate or key config or files without having the
replacements in places renders the WeUI inaccessible.
The only other place where FileUpload is currently used is for wifi certificates
for which the 'safe' handling is also preferred. Therefore make the default for
the FileUpload widget the safe handling and add a property self.unsafeupload that
allows for the old unsafe handling should it prove useful in some case.
Also allow to specify a file already on router instead of uploading a file.

The call to http.formvalue in order to read the csrf token causes
_parse_input to be triggered *before* controllers and cbi maps have
been built. This results in the failure of file uploads because
the file handler is not yet in place when _parse_input gets called,
and it is in _parse_input that POST data is parsed (including files).
To fix this we add the ability to write file fields to temporary
files (using mkstemp and unlink in nixio.file) and use this to
store file data until the filehandler is registered, with a
fallback to reading the file data into memory.
Once the filehandler callback gets registered we iterate
though all previously parsed (saved) files and copy the
data to the file handler, and then close the temporary
file (which finally removes because we unlinked after
creating the file, but didn't close the file so unlink
was deferred).
