Update third_party/waf/ to 2.0.4 to bring us closer to Python 3
This change requires a number of changes in buildtools/ too.

binutils 2.31 is going to change how shared libraries are linked, such
that they always provide their own local definitions of the _end, _edata
and _bss_start symbols. This would all be fine, except for shared
libraries that export all symbols be default. (Rather than just
exporting those symbols that form part of their API).
According to binutils developers, we should only export the symbols we
explicitly want to be used. We don't use this principle for all our
libraries and deliberately don't want to have ABI versioning control for
all of them, so the change I introduce here is to explicitly mark those
symbols that will always be added by default linker configuration with
binutils 2.31 as local. Right now these are '_end', '_edata', and
'__bss_start' symbols.

Utilities for Python libraries are built for a specific Python
version. Starting with Python 3, the Python version is recorded
in the shared library filename as an ABI tag, e.g. "pytalloc.cpython-34m.so.
The exact version doesn't matter for Samba's ABI check.
Replace the ABI tag with a simpler one that just records the major
version of Python.

Only filter out the symbol when positive match was not found and there is
negative match.
ABI signature file generator worked incorrectly for cases when mixture of
positive and negative matches were provided. This resulted in generating empty
signature file for libpdb since there was no catch-all positive match anymore.
Commit 9ba44cc610426fb558b49aa9680b5bdf55c29082 removed explicit '*' positive
match and corresponding vscript generator adds '*' by default if global match
list is empty, so this commit introduces feature parity into signature
generator.

abi_match keyword for samba libraries allows to selectively
apply ABI versions. samba_abi.py implied !sym to be used to
say 'all symbols but this one' but the actual demotion
of !sym to the local scope was not implemented.
Now abi_match='!sym' properly moves symbol to a local scope.
Signature parsing for structure objects was broken. Existing regexp
was greedingly cutting off additional curly brackets that belonged to
the first and last structure member.
This information has always been in the linked wiki page, but put it
in the build to unblock developers using platforms with slightly
different GDB output.
We can also assist this by improving the string normalisiation in the
ABI checker when example errors are provided.
It is better to build with the waf build and the full testsuite than
to avoid the waf build or not to use the developer options simply to
skip the ABI checker.

any new symbols.
The version entries also appear in the symbol table and removing them
(we always add an entry for the current version) breaks the ABI.
SAMBA_LIBRARY('libsmb/smbclient') can now be built, which
distinguishes it from the binary 'smbclient'

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.

- use 'va_list' instead of 'struct __va_list_tag *'
Using the C name for va_list is preferable
- add support for negative ABI name matches in abi_match=. That is
used to exlude ldb_*module_ops from the ldb ABI
- don't include the ldb module ops or backend ops in the ABI
