rework config.h stuff a little, fixing up numerous ifdefs etc. added some more for potentially smaller builds.

make the 'identify' command assume that a single decimal number is not an address (allowing it to be handled as a user id).
qcc: support default initialisers in function calls.
tweak filesystem code to try to flush individual files instead of discarding the entire fs hash.
fix 'snap' stuff.
other tweaks...
