package: add ABI version checking

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.
