Subject: [PATCH] Make exported headers use strict posix types
A number of standard posix types are used in exported headers, which
is not allowed if __STRICT_KERNEL_NAMES is defined. In order to
get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers
the default, we have to change them all to safe types.
There are also still some leftovers in reiserfs_fs.h, elfcore.h
and coda.h, but these files have not compiled in user space for
a long time.
This leaves out the various integer types (u_int32_t, uint32_t, u32,
uint and the signed and 8/16/64 bit variants thereof), which we may
want to do in an automated script instead.

This is my previous patch, ported to today's git. It's my last day
before my vacation, so I can't do the usual testing etc. on it.
Hopefully somebody else can take care of this.
