Andreas Arnez b4fd25c939 SPARC: Rename register maps from "*regset" to "*regmap"
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.

/* This file provids the (temporary) glue between the Solaris SPARC

/* Solaris 7 (Solaris 2.7, SunOS 5.7) and up support two process data
models, the traditional 32-bit data model (ILP32) and the 64-bit
data model (LP64). The format of /proc depends on the data model
of the observer (the controlling process, GDB in our case). The
Solaris header files conveniently define PR_MODEL_NATIVE to the
data model of the controlling process. If its value is
PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit
program.
GNU/Linux uses the same formats as Solaris for its core files (but
not for ptrace(2)). The GNU/Linux headers don't define
PR_MODEL_NATIVE though. Therefore we rely on the __arch64__ define
provided by GCC to determine the appropriate data model.
Note that a 32-bit GDB won't be able to debug a 64-bit target
process using /proc on Solaris. */
