Finish implementation of --all
* doc/cflow.1: Document the --all --all behavior
* doc/cflow.texi: Likewise.
* src/main.c: Increment all_functions for each -A option.
* src/output.c (tree_output): If one --all option is used, output graphs
for all top-level functions (i.e. functions, not reachable from other ones).
If used twice, output graphs for all global function.
* tests/all.at: New test.
* tests/Makefile.am: Add new test.
* tests/testsuite.at: Likewise.
