Now 'constraint cmd|package' is like 'needs' but sets a constraint
The command to 'needs cmd' and 'constraint cmd' can now take
a subcommand to check.
Add 'constraint|needs eval|expr' to make some constraint checks
simpler.

Avoid unexpected issues by concatenating multiple arguments.
This does create an incompatibility with early versions, but
it is generally trivial to convert existing code to one of two forms:
1. expr {$a + $b} -- usually correct
2. expr "$a + $b" -- usually incorrect

This means that instead of just [list index 2+1], we can now do
[list index end-$n*2+1]
This applies to:
lindex, linsert, lreplace, lset, lrange, lsort, regexp, regsub
string index,first,last,range
Also add tests for both direct integer expressions and indexes.
Still needs doc update.

For convenience, many commands now accept integer expressions
rather than only simple integers.
These are:
loop, range, incr, string repeat, lrepeat, pack, unpack, rand
This simplifies many cases where previously expr {} or $() was required.
e.g.
foreach i [range 4+1 2*$b] { ... }
string repeat 2**$n a

It is especially convenient to add -1 for something like:
lindex $list end-$BACK-1
or:
string range $str $p $p+$len-1

If the pattern begins with -, the internal invocation of regexp
will treat the pattern as an option. Fix this by adding -- to the
internal invocation of regexp.

aio [open], as well as similar commands return the name of the
created command. If this is done in the non-global namespace, the
returned name is implicitly scoped to the current namespace while
the actual command is created in the global namespace. Thus [close]
does not work when invoked in that namespace.
The solution is to return a fully qualified name, such as ::aio.handle3
Note that this may also be a problem for similar command such as
[proc] and [alias] that return command names.

Now an octal literal needs to be explicitly indicated with a leading
0o or 0O, otherwise the number is treated as decimal.
This patch also adds support for binary literals.
e.g. 0b101 0B1101

This was completely wrong. The arg order was wrong such that
when test constraints were specifed the test was always skipped!

Much closer to tcltest now, including constraints.
Try to get all appropriate tests running under both Jim and Tcl.
