Add x86_debug_reg_state to gdbserver
This commit introduces a new function, x86_debug_reg_state, that
shared x86 code can use to access the local mirror of a process's
debug registers. This function already existed in GDB and was
in use by GDB's x86_linux_prepare_to_resume. An equivalent was
written for gdbserver and gdbserver's x86_linux_prepare_to_resume
was modified to use it.
gdb/ChangeLog:
* x86-nat.h (x86_debug_reg_state): Move declaration to...
* nat/x86-dregs.h (x86_debug_reg_state): New declaration.
gdb/gdbserver/ChangeLog:
* linux-x86-low.c (x86_debug_reg_state): New function.
(x86_linux_prepare_to_resume): Use the above.
