Modify debug macros to have the same format through the codebase and use regular
ifs instead of ifdef.

Style - you are replacing aligned \ continuation with one-space \
continuation.  I don't know if we have a distinct preference, but it's
probably better to leave the style unchanged if checkpatch.pl doesn't
complain about either way.

As that's minor,

[resend, because my first attempt got:

   ----- The following addresses had permanent fatal errors -----
<qemu-devel@nongnu.org>
    (reason: 550 Invalid address in message header)

I think it was complaining about:
CC: open list:X86 <xen-devel@lists.xensource.com>
CC: open list:X86 <kvm@vger.kernel.org>

where the RFCs say you should enclose : inside "", as in:

CC: "open list:X86" <...>

to be fully compliant.]
