All C extensions must call Jim_PackageProvide()
make-c-ext ensures that Tcl extensions call Jim_PackageProvide()
if compiled in.

info frame allows access to source file/line for earler call frames
Implement 'stacktrace' to give a live stacktrace
And 'stackdump' to convert a stack trace to readable form
Update 'errorInfo' to use 'stackdump'
Also fix tailcall to retain source info

Also implement 'local' to declare/delete local procs
* Add tests/alias.test for testing alias, current, local
* proc now returns the name of the proc created
* Add helper 'function' to stdlib
Reimplement glob and case to use local procs
* This keeps these internal procs out of the global namespace

Improve the ability to rethrow errors
* Allow return to rethrow an error by accepting '-errorinfo stacktrace'
* Also, 'catch ... opts' now also stores opts(-errorinfo) on error
* Use these to provide better stack traces from 'case' and 'try'
* Implement 'return -level'
Make try/on/finally more Tcl 8.6 compatible
* With support for 'on' handlers and docs
Add support for catch options to try
* Otherwise it's hard to use try to catch signals
Improvements to signal handling
* catch -signal now sets a list of the handled signals as the result
* catch -signal won't execute the body at all if a handled signal is pending
* up to 64 (jim_wide) signals can now be handled
* if catch -signal is nested, the innermost catch will catch the error
* new 'signal catch' allows ignored/blocked signals to be examined and cleared.
* update docs on signal handling
exec should indicate which signal killed the child

*: Add optional arg to catch, opts, like Tcl 8.5 to allow access to the
code given by 'return -code'
*: Use -- to signify end of options to catch
*: 'info returncodes' can give the name of a single code
*: Fix 'case' to handle 'return -code' properly

*: Get rid of JIM_ERR_ADDSTACK and use interp->addStackTrace instead
*: 'return -code error' doesn't add a stack frame
*: Rename _file_copy to {file copy} for better error messages
*: Use 'return -code' to prevent excessive levels in the stack trace
Also rename info_nameofexecutable to {info nameofexecutable}

*: Default to the same as Tcl. Not signal, eval, exit.
*: Use 'catch -exit' to also catch exit.
*: Also map for standard return codes: [info returncodes]
*: Also Jim_ReturnCode()
*: Add Jim_FindByName() for searching in a char* array
*: Fix 'info nameofexectutable' if $::jim_argv0 is not set
