wait queue primitives implementation using pthread API

modify top-level lnet/include/libcfs/libcfs.h,kp30.h,portals_utils.h
files to conditionally include header files for solaris port.

create Solaris port files and shared posix-*.[ch] files for both
Linux and Solaris ports.

The posix-*.[ch] files are currently noop
(posix threads API calls should be added there).

Allow user-level OST build. This patch adds --enable-uoss configure switch, .am
files are modified to include OST and obdfilter subdirectories in user-level

move configuration of capa/pag/gss back to lustre-core.

basic support for PAG, ported from HEAD.

more fixes of configuration of capability and gss.

hmac checking in lustre-core.m4 break kerneless building. move to
lustre-build-linux.m4 and use existing LB_LINUX_CONFIG.

add LC_CONFIG_SPLIT in lustre-build.m4

on both b_new_cmd and b1_5, it's obviously not working for some cases:
http://buffalo.lustre.org:8080/display_report.pl?report_id=278455
I am not sure why though.  It would seem like lustre.spec.in is not getting
processed by configure, but all indications are that it is.  Why is the
@RPM_LIBIAM_PATH@ substitution not being done then?

- replace all memcmp of fids by lu_fid_eq;
- allocate new fid for create case in ll_revalidate_it() in case of doing "goto do_lookup";
- removed needless lmv_fld_lookup() in lmv;
- fixed lmv_obj refcount management in error cases;
- comments are adjusted to be coherent with 80 columns style.

Add --disable-readline option, make it the default for --enable-bgl.

r=adilger
Some implicit options when --enable-bgl is specified.

r=+adilger
Add an --enable-bgl flag for future BGL specific tunings and disable the -m64
compiler flag checking if set.

remove unused LC_CONFIG_QUOTA in lustre-build.m4.

remove check for if_dqblk/dqinfo.
change parameters type from int to __u32, since it's used
in ioctl. and make it align. (according to Andreas' advice)

Landing LNET (b1_4_newconfig)

add makefile for  standalone quota.
