[PATCH 0/5 v7] Common code cleanups (first four, and one new)

[Gary Benson <gbenson@redhat.com>]

Hi all,

This series contains updated versions of the first four common
cleanups patches I last posted Monday, and a new patch to deal
with issues regarding the debug_hw_points flag.

Patches 1-3 are unchanged from their previous versions.

The debug_hw_points code was moved from patch 4 into patch 5.
Patch 4 now contains only the new functions debug_printf and
debug_vprintf.  It is otherwise unchanged from the previous
version.

Patch 5 is a new patch.  gdbserver has a flag, debug_hw_points,
that switches on some debug printing in the x86 and AArch64 Linux
ports.  GDB's x86 and AArch64 Linux also define debug_hw_points,
with identical meaning, accessed via "maint set/show show-debug-regs".
GDB's Linux MIPS port also has "maint set/show show-debug-regs",
but there the variable is called maint_show_dr.  In some ports the
flag is static to one file, in other ports and in gdbserver it is
global.  Patch 5 defines one global for this, show_debug_regs, in
common-debug.h.  All other definitions are removed, and all ports
are modified to use the new global.

Is this ok to commit?

Doug, if patches 1-4 are ok please let me know (regardless of the
status of 5) so I can commit them.  (If all five are ok then great!)

Thanks,
Gary
