/*
** Print an error message, rollback all databases, and quit.  These
** routines never return and produce a non-zero process exit status.
**
** The main difference between fossil_fatal() and fossil_panic() is that
** fossil_panic() makes an entry in the error log whereas fossil_fatal()
** does not. On POSIX platforms, if there is not error log, then both
** routines work similarly with respect to user-visible effects.  Hence,
** the routines are interchangable for commands and only act differently
** when processing web pages. On the Windows platform, fossil_panic()
** also displays a pop-up stating that an error has occured and allowing
** just-in-time debugging to commence. On all platforms, fossil_panic()
** ends execution with a SIGABRT signal, bypassing atexit processing.
**
** Use fossil_fatal() for malformed inputs that should be reported back
** to the user, but which do not represent a configuration problem or bug.
**
** Use fossil_panic() for any kind of error that should be brought to the
** attention of the system administrator or Fossil developers. It is to
** be avoided for ordinary errors of usage, data entry, or I/O errors.
