Now that defs.h, server.h and common-defs.h are included via the `-include` option, it is no longer necessary for source files to include them. Remove all the inclusions of these files I could find. Update the generation scripts where relevant. Change-Id: Ia026cff269c1b7ae7386dd3619bc9bb6a5332837 Approved-By: Pedro Alves <pedro@palves.net>

/* The underlying idea is that when a Windows program is terminated by
|
|
a fatal exception, its exit code is the value of that exception, as
|
|
defined by the various EXCEPTION_* symbols in the Windows API
|
|
headers. We thus emulate WTERMSIG etc. by translating the fatal
|
|
exception codes to more-or-less equivalent Posix signals.
|
|
|
|
The translation below is not perfect, because a program could
|
|
legitimately exit normally with a status whose value happens to
|
|
have the high bits set, but that's extremely rare, to say the
|
|
least, and it is deemed such a negligibly small probability of
|
|
false positives is justified by the utility of reporting the
|
|
terminating signal in the "normal" cases. */
