[Qemu-devel] [PATCH for-4.0 v7 02/27] qapi: do not define enumeration value explicitly

[Marc-André Lureau]

The C standard has the initial value at 0 and the subsequent values
incremented by 1. No need to set this explicitely.

This will prevent from artificial "gaps" when compiling out some enum
values and having unnecessarily large MAX values & enums arrays, or
simplifying iterating over valid enum values.

Whenever config-host.h is changed, all the enum/types are recompiled.
