Clear the naming confusion about "regset" versus "sparc*regset". The
latter was used to represent the *map* of a register set, not the
register set itself, and is thus renamed accordingly.
The following identifiers are renamed:
sparc32_bsd_fpregset => sparc32_bsd_fpregmap
sparc32_linux_core_gregset => sparc32_linux_core_gregmap
sparc32_sol2_fpregset => sparc32_sol2_fpregmap
sparc32_sol2_gregset => sparc32_sol2_gregmap
sparc32_sunos4_fpregset => sparc32_sunos4_fpregmap
sparc32_sunos4_gregset => sparc32_sunos4_gregmap
sparc32nbsd_gregset => sparc32nbsd_gregmap
sparc64_bsd_fpregset => sparc64_bsd_fpregmap
sparc64_linux_core_gregset => sparc64_linux_core_gregmap
sparc64_linux_ptrace_gregset => sparc64_linux_ptrace_gregmap
sparc64_sol2_fpregset => sparc64_sol2_fpregmap
sparc64_sol2_gregset => sparc64_sol2_gregmap
sparc64fbsd_gregset => sparc64fbsd_gregmap
sparc64nbsd_gregset => sparc64nbsd_gregmap
sparc64obsd_core_gregset => sparc64obsd_core_gregmap
sparc64obsd_gregset => sparc64obsd_gregmap
sparc_fpregset => sparc_fpregmap
sparc_gregset => sparc_gregmap
sparc_sol2_fpregset => sparc_sol2_fpregmap
sparc_sol2_gregset => sparc_sol2_gregmap
Also, all local variables 'gregset' and 'fpregset' are renamed to
'gregmap' and 'fpregmap', respectively.
