Joseph Myers e78dc67889 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.
