remove quit_sage() command from all.py top level #8784
Description
It is stupid that it is this easy to accidentally destabilize and segfault Sage. Also, having a function "quit_sage()" available at the sage: prompt by default that does not quit sage, is dumb.

The fix is to rename quit_sage() somehow and change all code that calls it.
