Adds leaner error-reporting functions for simple cases, and documents the
purpose of the different facilities available in QEMU.
Although not all printf+exit/abort are replaced with the proper functions, a few
are ported as an example.
Changes in v6
=============
* Rebase on 074d1cc [David Gibson].
* Fix typo in documentation [Eric Blake].
* Clarify when to use fatal/abort [Eric Blake].
Changes in v5
=============
* Fix typo in documentation [Eric Blake].
Changes in v4
=============
* Introduce 'error_report_fatal()' and 'error_report_abort()' functions
[suggested by Thomas Huth].
* Repalce all existing uses of 'error_setg(error_fatal)' and
'error_setg(error_abort)' with 'error_report_fatal()' and
'error_report_abort()'.
* Replace all uses of 'exit()' with 'error_report_fatal()' in 'target-ppc'.
* Replace all uses of 'abort()' with 'error_report_abort()' in 'target-ppc'.
Changes in v3
=============
* Drop special object 'error_warn' in favour of raw 'error_report()'
[suggested by Markus Armbruster].
Changes in v2
=============
* Split in two patches.
* Explicitly add a warning error object.
