compiler/parse_item.m:
Don't accept `:- external' items.
compiler/prog_item.m:
Require the presence of a pred_or_func flag on external pragmas.
They are specified by `:- pragma external_{pred/func}' pragmas,
which are still supported.
compiler/parse_pragma.m:
When parsing external_{pred/func} pragmas, allow the predicate name
to contain a module qualifier; they were allowed on `:- external' items.
We do require the module qualifier to specify the expected (i.e. the
current) module.
compiler/add_pragma.m:
compiler/parse_tree_out_pragma.m:
compiler/recompilation.version.m:
Conform to the changes above.

Modernize the code where needed, replacing DCGs with state variables.

Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the tests
that check compiler error messages, expect the new line numbers.
browser/cterm.m:
browser/tree234_cc.m:
Import only one module per line.
tests/hard_coded/boyer.m:
Fix something I missed.
tests/valid/*:
Renamed `*.nl' as `*.m'.
Added a few new test cases.
Removed a couple of duplicate test cases.
Fixed up the Mmake file so that `mmake check' now works.
