  Log Message:
  -----------
  Replace 'struct ucontext' with 'ucontext_t' type

glibc used to have:

   typedef struct ucontext { ... } ucontext_t;

glibc now has:

   typedef struct ucontext_t { ... } ucontext_t;

(See https://sourceware.org/bugzilla/show_bug.cgi?id=21457
 for detail and rationale for the glibc change)

However, QEMU used "struct ucontext" in declarations. This is a
private name and compatibility cannot be guaranteed. Switch to
only using the standardized type name.
