1) Move all debug preprocessor flags out into make files
2) Add support for remaining preprocessor flags to be set by ENV variables
3) Add support for HAL tracing to include device name

Linux 2.6.24 introduces a sysctl checker that disallows using arbitrary
ctl_name values for sysctl entries. The entries with non-standard
values should set ctl_name to CTL_UNNUMBERED.
On the other hand, using consistent non-zero ctl_name values is required
for older kernels (tested on Linux 2.4.33.3 from Slackware 11).
Thus the solution is to use CTL_UNNUMBERED on Linux 2.6.24+ and the
original values in the older kernels. Move CTL_AUTO and DEV_ATH to
include/compat.h and define them correspondingly.
When copying sysctl entries, check procname for being non-zero, since
ctl_name is zero (CTL_UNNUMBERED) on Linux 2.6.24 and newer.
For the same reason, don't use ctl_name to distinguish entries in
ath_sysctl_template, use extra2 instead.
