Added xml patch to mysqldump. 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.

Added xml patch to mysqldump. 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.
