this fixes a problem found by obnox where the -L path for CUPS was put
before the path to internal libraries. The install path for CUPS
happened to be the same as for a old system libtevent, which meant we
linked against the old tevent instead of the correct one from our
private library paths.
The problem was that we were adding the -L paths directly to the
ldflags. The waf core code (in ccroot.py) only adds more paths if they
are not there already. So by adding it in ldflags it was not added at
the end of the list. The fix is just to not do the -L processing in
wafsamba and let the waf core do it in the right order

This library was tiny - containing just two public functions than were
themselves trivial. The amount of overhead this causes isn't really worth the
benefits of sharing the code with other projects like OpenChange. In addition, this code
isn't really generically useful anyway, as it can only load from the module path
set for Samba at configure time.
Adding a new library was breaking the API/ABI anyway, so OpenChange had to be
updated to cope with the new situation one way or another. I've added a simpler
(compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.

when we change our build rules to move a C file, we need to remove the
old ('stale') .so and .o files from the build directory, or they may
be used as part of the new build, which means that old code will be
linked in.
This expands the list of stale files that we remove on rule changes to
include .so and .o files

having the git version in our version.h in the build tree is annoying
for developers, as every time you commit or rebase you need to spend
several minutes re-linking. This changes it to use the git version
only on install, which is much more useful as when you actually
install the binaries you may be using them in a way that reporting the
version is useful

this fixes 'make bin/smbd' to work correctly with the waf build. It
didn't work before as smbd is actually 'smbd/smbd' internally and we
tried to use the target name 'smbd'. The new approach reads the
symlink to get the right target.
This also speeds up the null build by quite a lot
the SAMBA_SCRIPT() function was not always triggering correctly. The
base problem was that we were using a target outside the build
tree. This implements a simpler solution where we just create the
links directly in SAMBA_SCRIPT() rather than creating a waf task

Normally under UNIX, uninitialized non-static global variables get
placed in the "common" section, where they are merged at link time.
This means if two C files define "int debug", they will end up
referring to the same variable. Or if one does "float level" and the
other does "int level" you'll get an accidental union.
Such bugs can be hard to track down; fortunately GCC offers
-fno-common to disable this feature. It didn't reveal any places
which need fixing, however).

the s3 waf build will use this to say that we should allow public
headers that contain references to non-public headers. In the s4 build
that is not allowed, but the s3 build does not yet have clean public

This function is a wrapper around waf's check_python_header.
It avoids searching more than once for the headers bringing a small
speed improvement and a better lisibility of the logs.
But it's mainly to avoid a nasty bug when python libraries are in path
pointed by python_LIBPL (ie. /usr/local/lib/python2.6/config/) instead
of python_LIBDIR (ie. /usr/local/lib).
On the first call waf will correctly find that in order to link with
python libs it needs to add -L$python_LIBPL.
But on the next calls of check_python_headers, waf will use both the
current library path value (ie. -L/usr/local/lib/python2.6/config) and
-L$python_LIBDIR (ie. /usr/local/lib/) which will make him beleive that
python libraries are in $python_LIBDIR which at the end will make the
final link test fails in check_python_headers as it will not use the
good directory.
So by avoiding calling check_python_headers more than once we avoid
making waf fooling itself.

This changes our version-script generation to use the ABI files that
are saved in git with each version number change of our public
libraries.
We use these ABI files to generate a linker version script that gives
the exact version number that each symbol was introduced. This
provides us with automatic fine grained symbol versioning.

This enables symbol version on our libraries, if the system supports
it
If the library is a public library, then set the symbol version based
on the major number. If it is a private library then set it based on
the full version number (which will include the git hash if
available).
This ensures that applications using our libraries don't use symbols
from other libraries that they may be linked to. It also ensures we
only use the right version of any private libraries.
Note that the linker ends up generating both a version and unversioned
symbol for all symbols. This means existing users of our public
libraries will continue to work, with symbols resolved to the
unversioned symbol. When applications are re-linked they will bind to
the specific symbol version.

Fix the library extension from .so to .sl
Add full path to library when linking this is needed due to a strange
behavior of HP-UX:
This command: gcc demo demo.c -L dir1/dir2/ -lsomelib

Somehow like a partial rpath, it has the first impact of fooling waf
detection of wether the plateform support libraries or not (leading to
being unable to compile samba on HPUX) and the impact of having non
