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.

This means that $variable references and [commands] are not expanded.
This should mitigate security concerns when using the 'integer expression' feature.

It means that you must do:

    string repeat a $i*4

Not:

    string repeat a {$i*4}

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

A command may return NULL, but set an error (e.g. Server closed the connection).
In this case, make sure to return the error.

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 build host doesn't have neither jimsh nor tclsh installed,
during 'configure' the autosetup will build 'autosetup/jimsh0'
inside the source tree. This happens also when out-of-tree build
is used.
Making dirty the source tree during out-of-tree build causes
applications that use jimtcl as submodule (e.g. OpenOCD) to fail
at 'make distcheck'.

Modify 'autosetup-find-tclsh' to build 'jimsh0' in the current
folder. For jimtcl project it would be the root of the source tree
or the root of the out-of-tree build.
Update 'Makefile.in' to search for 'jimsh0' in the new path during
'distclean'.

The generation of this field makes the resulting Tcl.html different between builds,
as it records the time of generation, remove this as it causes jimtcl rpms for different
arches (on RHEL/Fedora) to have a file conflict on Tcl.html.

local regex to jim_regcomp, jim_regexec, etc.
