While building software that sets _POSIX_C_SOURCE=200809L and uses
stat.st_mtim for ARM, it was noticed that st_mtim was not defined.
This seems to be because common/bits/stat.h was picked up, which does
not take __USE_XOPEN2K8 as a reason to enable st_mtim and related
fields. This appears to be an oversight, and porting the check from
common-generic/bits/stat.h to other architectures does indeed fix the
build issue.
This patch is based on commit 50bd6d06e ("Fix memory corruption due to
struct stat field").

Rename various spare fields in structs to include a namespace
This should avoid accidental clashes with uses of the __unused symbol
in upstream projects. eg currently it causes a compile error in dhcpcd 8.x
due to their re-use of the __unused symbol as a macro
This follows the style of glibc which does something equivalent

This matches a similar change made to glibc.
No functional changes here.

Fill out the stat structure so that the nanosecond resolution support is
always available. There is a small code size increase for a few ports
(three additional assignments in xstatconv), but otherwise everything
should remain the same.
While we're here, punt __old_kernel_stat from the few headers that still
define it as it is unused in uClibc and causes compile errors after these
nanosecond changes.

__USE_FILE_OFFSET64 is defined. This was the case for all
architectures except those that use packed structures by default
(i.e., CRIS).

type of 'struct stat' and 'struct stat64' so they use consistant types.
This change is the result of a bug I found while trying to use GNU tar. The
problem was caused by our using kernel types within struct stat and trying to
directly compare these values with standard types. Trying an 'if (a < b)' when
'a' is an 'unsigned long' and 'b' is an 'int' leads to very different results
then when comparing entities of the same type (i.e. time_t values)....
Grumble. Nasty stuff, but I'm glad I got this out of the way now.
As a result of this fix, uClibc 0.9.17 will not be binary compatible with
earlier releases. I have always warned people this can and will happen.

directly. Eliminate all the attendant baggage. Fix internal
types to match kernel types more closely.

and to better support each arch. This is a really big patch...
