Ok, people are probably going to hate me for this... This commit changes the
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.
