In addition to "on codes ..."
it is now possible to trap on errorcode with
"trap sublist ..."

e.g.

try {
  ...
} trap CHILDSTATUS {msg opts} {
  ...
}

bootstrap jimsh doesn't have garbage collection, so move

When a reference is used as a command name (e.g. in oo.tcl) it
is created in the global namespace as ::<reference...

The current check for references that are commands with a reference
count of 1 doesn't take this into account so these references
were not being garbage collected.

Don't try to dup2() a file descriptor that is already
correct. This can happen if, for example, stdin is closed
and exec redirects stdin from a file, thus opening the input

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

jim.h now includes JIM_ABI_VERSION that should be incremented whenever
the ABI changes. Then all loadable modules should call Jim_CheckAbiVersion()
to make sure they are loaded against the correct version.

Add Jim_PackageProvideCheck() that does both Jim_CheckAbiVersion()
and Jim_PackageProvide() to simplify the implementation of loadable extensions.

Also rename the "big" sqlite3 extension to just sqlite to avoid a naming conflict with
the smaller jim-sqlite3 extension.

If no 'check' is provided, we assume that the checks passed.
If pkg-config is specified, but no other check, use 'check false'
to ensure the module is disable if the pkg-config checks don't pass.

also built, and add a dependency on libhiredis-dev to 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
