`mw.loadJsonData` in mw.lua throws an error if the input argument is
not a string. The error message should refer to the type of the input
argument `module`, not that of the variable `arg` (which is usually
undeclared, giving the type `nil`).
This also necessitates updating test `mw.loadJsonData, bad title (1)`
in CommonTests.lua, which checks for the error message if the input
is the number 0; the correct message should say "got number", not
"got nil".

Defense in depth: catch the error early when calling mw.language.new()
with a non-string `code` argument; but also check late when popping
the code off the argument array in case something altered the code
property after construction.

Added escapes for "!" and ";" as well as additional escapes
at beginning and end of string.

In order to avoid misleading the caller, set some title properties to
nil for interwiki links. That value should still be falsey, but can
prevent making unwarranted assumptions about the destination of
interwiki links.
Split from I847ac4b7587b98be06b25fe14765e9efdc7b774d because this
could possibly have effects on existing modules.

This allows conversion of MediaWiki-internal codes to standardized

Using code by David Manura, published at lua-users.org/wiki/StringTrim
Note '\t\r\n\f ' is replaced with '%s', thus '\v' (vertical tab) is added to the characters trimmed by default.

mw.loadData() allows for optimizing the loading Lua tables by requiring
only one parse and lookup. However it's often easier for people to
write/maintain bulk data in JSON rather than Lua tables.
mw.loadJsonData() has roughly the same characteristics as mw.loadData()
and it can be used on JSON content model pages in any namespace.
As noted on the linked bug report, it's possible to already implement
this by writing a wrapper Lua module that loads and parses the JSON
content. But that requires a dummy module for each JSON page, which is
just annoying and inconvenient.
Test cases are copied from the mw.loadData() ones, with a few omissions
for syntax not supported in JSON (e.g. NaN, infinity, etc.).

For the most part, it is a good idea to avoid global variables and use
`local` variables instead. Quoting from the ScopeTutorial[1], "The
general rule is to always use local variables, unless it's necessary for
every part of your program to be able to access the variable (which is
very rare)."
Wikimedia module authors have written "Module:No globals", which errors
on the use of any global variable. On the English Wikipedia, this is
used on 32% of pages (18 million). Wikidata[2] indicates that it's been
copied to 334 other wikis.
Lua itself distributes an extra named "strict.lua"[3], which is what
this is based off of. Similar to bit32.lua, this is a pure-Lua library
that can be imported/enabled with `require( "strict" )` at the top of a
module.
The two changes I made from Lua's strict is to exempt the `arg` key,
which is used internally by Scribunto, and remove `what()`, since we
don't enable access to `debug.getinfo()` for security reasons.
