traces: provide a means to get short m4 traces
Let --trace=m4-early dump all the logs from the start (as --trace=m4
used to do), and have --trace=m4 now start traces only when actually
working of the user's grammar.
Can make a big difference in the case of small inputs. E.g.
$ bison -S tests/testsuite.dir/001/input.m4 tests/testsuite.dir/001/input.y --trace=m4 |& wc
3952 19446 251068
$ bison -S tests/testsuite.dir/001/input.m4 tests/testsuite.dir/001/input.y --trace=m4-early |& wc
19491 131904 1830495
* data/skeletons/traceon.m4: New.
* src/getargs.h, src/getargs.c: Introduce --trace=m4-early.
* src/output.c (output_skeleton): Adjust for --trace=m4 and --trace=m4-early.
