Made innodb to compile more cleanly with debugging options
enabled. Fixed a few bugs and found a few possible bugs, which
I hope Heikki will check. Comments needs to be fixed too. Some
while() functions should be changed to do ... until for documenting
purposes, because some of them must and will be processed at least
once, or a variable would be used uninitialized.

Regards,
Jani
