configure.ac: add a generic --enable-debug, replace --enable-hashmap-debug

There will be more debugging options later.
 --enable-debug will enable them all.
 --enable-debug=hashmap will enable only hashmap debugging.

Also rename the C #define to ENABLE_DEBUG_* pattern.

NOTE: We add the debugging code to hashmap.{c,h} but do not
add the option in configure.ac.  We may do so at a later time.
