400704d038 Added macro BX_FATAL() that works like BX_PANIC(), but with hardcoded action
"fatal". It can be used for all cases when there is no workaroud present to
avoid application crash or incorrect simulation behaviour. As a first step now
using BX_FATAL() for some data structure size and bit field errors.

7eee83a1d9 Some work on the logio code.
- Show message box (modified ask dialog) in method fatal() if not called after
  ask dialog or pressing power button.
- Removed code for unsupported actions "ask" and "fatal" from info() method.
- Some related small code cleanups.

b9b9082e86 Rewrite of the "ask" and "warn" dialog framework.
- Added new symbol BX_SYNC_EVT_LOG_DLG and method log_dlg() in siminterface to
  handle the cases "ask", "warn" and "quit".
- Added support to change action from "warn" to "report in the "warn" dialog
  (sdl2, win32 and wx).
- TODO: Add quit message box for the log action "fatal" and add BX_FATAL()
  macro for all cases where continuing after BX_PANIC would be dangerous.

b85e582f44 Always put va_start() and va_end() around formatted output. Since fatal() never
returns, the va_end() must appear after vsnprintf(). That seems to fix the
recently reported "format string vulnerability", so please verify this fix.
