SPARC sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in the SPARC
sys/ucontext.h header. These are similar to changes made previous to
other sys/ucontext.h headers, where the SPARC header was excluded from
those previous patches because of its complexity.
Tested for SPARC with build-many-glibcs.py.
