stddef.h: Introduce sizeof_field()
The size of fields within a structure is needed in a few places in the
kernel already, and will be needed for the usercopy whitelisting when
declaring whitelist regions within structures. This creates a dedicated
macro and redefines offsetofend() to use it.
Existing usage, ignoring the 1200+ lustre assert uses:
$ git grep -E 'sizeof\(\(\((struct )?[a-zA-Z_]+ \*\)0\)->' | \
grep -v staging/lustre | wc -l
65
