When the function was later reused for racks, rows and locations, this logic didn't deliver working URLs. Add necessary checks such that this feature only tries to work when it can work, add a date format mouse hint, add minimal reporting of RackCode parsing errors and move some code around for clarity.

Subject: [PATCH 045/138] put usort_portlist() right (GH #199)

The input to sortPortList() is an array of arrays, if it is an array of
anything else the function (since commit 07d22ce) will use array_fetch()
on the elements anyway, causing issues downstream. Vladimir Sukhonosov
had reported numerous PHP warnings in this regard.

Fix usort_portlist() to feed proper argument into sortPortList().

Subject: [PATCH 046/138] check argument type in array_fetch()

If the argument is not an array, it is a bug in the code as arguments to
that function come from other functions, not directly from user input.
Raise an exception before the broken code makes any [more] damage. Add
more tests.

Subject: [PATCH 050/138] omit the PHP closing tag at EOF in all PHP files

"If a file is pure PHP code, it is preferable to omit the PHP closing tag
at the end of the file. This prevents accidental whitespace or new lines
being added after the PHP closing tag, which may cause unwanted effects
because PHP will start output buffering when there is no intention from
the programmer to send any output at that point in the script."

Subject: [PATCH 052/138] RTSNMPDevice: handle SNMP versions stricter

There is no gain in assuming that if SNMP version is not 1, not 2 and
not 3, it means it is 1. Keep it simple.

Subject: [PATCH 053/138] only use the PHP opening tag once per file

There used to be a few code blocks that switched PHP interpreting on and
off with PHP tags, convert those to use either heredoc or plain echo as
that is the usual syntax for this purpose elsewhere in the code. Fixup
some indentation while at it.

* renderInstallerHTML()
* renderInterfaceHTML()
* renderIndex()
* dragon()
* renderSNMPPortFinder()
* renderPopupHTML()
* printStatic404()
* renderUpgraderHTML()
