Don't use kernel's ATTR_* attributes over the network since the client and MDS
may run different kernels. Instead, use MDS_ATTR_* attributes (defined in
lustre_idl.h) for sa_valid.

Add LNET router traceability for debug purposes

If a checksum failure occurs with a router as part of the IO path, the NID of
the last router that forwarded the bulk data is printed so it can be
identified.

introduced.

- enable all traces and debugs by default to not hurt anyone who not aware of this and allow customers gather all logs by default;
- added compile warning for case CDEBUG is disabled;
- fixes in configure keys, using AC_ARG_ENABLE(feature) implies that bash variable names is $enable_feature.

Implements following configure keys:

--disable-libcfs-cdebug - disable libcfs CDEBUG, CWARN - enabled by default
--enable-libcfs-trace - enable libcfs ENTRY/EXIT - disabled by default
--disable-libcfs-assert - disable libcfs LASSERT, LASSERTF - enabled by default

Cmd3 found that disabling all of this contributes to performance at the range of 10-15%. This is inspected many times. Lustre source code is checked by hands for possible side effects from disabling LASSERT, etc. If you have any problems with this - please let me know.

Correctly assign microseconds to microsecondsand seconds to seconds.

Bugzilla   : 11684
Description: Added D_NETTRACE for recording network packet history
	     (initially only for ptllnd).  Also a separate userspace
	     ptllnd facility to gather history which should really be
	     covered by D_NETTRACE too, if only CDEBUG recorded history in
	     userspace.
