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.

There is no reason to allow a reference to contain leading and/or
trailing white space, so remove this check and simply treat
it as an invalid reference.

In order to test bootstrap jimsh, it is very helpful
if it can pass all the unit tests.
- Set tcl_platform(bootstrap) to 1 for bootstrap jimsh or 0 otherwise
- Use getref to determine in we have references, not ref since we
implement a poor-man's ref for bootstrap jimsh
- bootstrap jimsh package doesn't return a "Can't load package"
message if loading the package fails
- exec tests using [open |command] need pipe
- bootstrap jimsh can't set file times with [file mtime]

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

Hash tables used to store variables are now use Jim_Obj keys rather
than allocated char *, so embedded nulls are supported.
This is generally a performance win as the existing Jim_Obj can be used
as the key.

In case the index is invalid, the string should contain -MAX_INT
