5d360b
Make DumpState and endian conversion routines available for arch-specific dump
5d360b
code by moving into dump.h. DumpState will be needed by arch-specific dump
5d360b
code to access target endian information from DumpState->ArchDumpInfo. Also
5d360b
break the dependency of dump.h from stubs/dump.c by creating a separate
5d360b
dump-arch.h.
5d360b
5d360b
This patch doesn't change any functionality.

[ rebased on top of current master branch,
5d360b
  renamed endian helpers to cpu_to_dump{16,32,64},
5d360b
  pass a DumpState * argument to endian helpers,
