We added @error_warn some two years ago in commit 3ffef1a55c (error:
add global &error_warn destination). It has multiple issues:
* error.h's big comment was not updated for it.
* Function contracts were not updated for it.
* ERRP_GUARD() is unaware of @error_warn, and fails to mask it from
error_prepend() and such. These crash on @error_warn, as pointed
out by Akihiko Odaki.
All fixable. However, after more than two years, we had just of 15
uses, of which the last few patches removed seven as unclean or
otherwise undesirable, adding back five elsewhere. I didn't look
closely enough at the remaining seven to decide whether they are
desirable or not.
I don't think this feature earns its keep. Drop it.

Headers in include/sysemu/ are not only related to system
*emulation*, they are also used by virtualization. Rename
as system/ which is clearer.
Files renamed manually then mechanical change using sed tool.
