* app_hooks: add display_error; can be used by atlas to override our dialog box * lots of small fixes (mostly pertaining to headers) * debug: clean up display_error, protect from reentrancy, fix a few edge cases (e.g. error message from dtor -> exit pressed -> suppress all subsequent errors) * delay_load: add warning: NLSO ctors are unreliable since we're compiling into static lib This was SVN commit r4009.
