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.

Only on unix systems, wait for any child process
This was broken with a recent commit, so add an explicit test

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]

- fix popen [open "|pipeline ..."] to return meaningful status in close
(but note that stderr is not captured)
- popen pipelines can now be used as the target of exec redirection
- overally improvements to exec on windows. Now crt file descriptors
are used throughout
- add support for [pid], [wait] and popen on windows
- os.wait is now wait, and integrates with [exec ... &] to be able
to wait for running background tasks
- [socket pipe] is now also [pipe] and is supported on windows
- [file tempfile] is supported on windows
- move duplicated code between jim-aio.c and jim-exec.c to jimiocompat.c
- Fix [exec] on windows to match unix semantics wrt sharing the parent stream
unless redirected rather than using /dev/null
- On windows redirect to or from /dev/null is automatically converted to NUL:
- If signal support is disabled, implement a minimal Jim_SignalId() for exec and wait
- aio now supports getfd, to return the underlying file descriptor.
This is used by exec to support redirection, and allows popen channels
to support exec redirection.

It is necessary to read output from the pipe before waiting
for children to exit to avoid the output filling up and blocking.
The error results still needs to be read after the children have
exited, since it is read from a temp file, not a pipe.
Increase the length of the input to test exec-8.1 to catch
the problem.

This also involves some restructuring of the existing
implementation to allow for as much reuse as possible.

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