Improve handling for Source: entries

Internal housekeeping to prevent "Use of undefined...." errors
Move filename-extraction into preamble parse; I have yet to see a live use case for always retrieving a file from a remote source.
Don't try to add a null "main" source to the source package; this would add all files in %_topdir/SOURCES to the .sdeb whether they're really listed in a SourceNN: entry or not.

1840	=head1 DESCRIPTION
1841
1842	debbuild attempts to build Debian-friendly semi-native packages from RPM spec files,
1843	RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1844	options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1845	modules should be handled via CPAN+dh-make-perl instead as it's simpler than even tweaking
1846	a .spec template.
1847
1848	As far as possible, the command-line options are identical to those from rpmbuild, although
1849	several rpmbuild options are not supported:
1850
1851	--recompile
1852	--showrc
1853	--buildroot
1854	--clean
1855	--nobuild
1856	--rmsource
1857	--rmspec
1858	--sign
1859	--target
1860
1861	Some of these could probably be trivially added. Feel free to send me a patch. ;)
1862
1863	Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1864	you'll have to make heavy modifications anyway.
1865
1866	If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1867	promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1868
1869	=head1 ASSUMPTIONS
1870
1871	As with rpmbuild, debbuild makes some assumptions about your system.
1872
1873	=over 4
1874
1875	=item *
1876
1877	Either you have rights to do as you please under /usr/src/debian, or you have created a file
1878	~/.debmacros containing a suitable %_topdir definition.
1879
1880	Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1881	where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1882	requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1883	some subdirectories are created automatically as needed, but most are not.
1884
1885	=item *
1886
1887	/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1888	executing shell scripts for much of their functionality. By default, debbuild also creates
1889	install trees under /var/tmp - however this is (almost) entirely under the control of the
1890	package's .spec file.
1891
1892	=item *
1893
1894	If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1895	match, or be suitably symlinked one direction or another so that both programs are effectively
1896	working in the same tree. (Or you could just manually wrestle files around your system.)
1897
1898	You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1899	if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1900	%_topdir macro definition, although there are many more things that rpmbuild can use from
1901	~/.rpmmacros.
1902
1903	=back
1904
1905	=head1 ERRATA
1906
1907	debbuild deliberately does a few things differently from rpm.
1908
1909	=head2 BuildArch or BuildArchitecture
1910
1911	rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
1912	that for all packages. Debian's repository system is fairly heavily designed around the
1913	assumption that a single source package may generate small binary (executable) packages
1914	for each arch, and large binary arch-all packages containing shared data.
1915
1916	debbuild allows this by using the architecture specified by (in order of preference):
1917
1918	=over 4
1919
1920	=item * Host architecture
1921
1922	=item * BuildArch specified in .spec file preamble
1923
1924	=item * "Last specified" BuildArch for packages with several subpackages
1925
1926	=item * BuildArch specified in the %package section for that subpackage
1927
1928	=back
1929
1930	=head2 Finding out what packages should be built (--showpkgs)
1931
1932	rpmbuild does not include any convenient method I know of to list the packages a spec file
1933	will produce. Since I needed this ability for another tool, I added it.
1934
1935	It requires the .spec file for the package, and produces a list of full package filenames
1936	(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
1937	This includes the .sdeb source package.
1938
1939	=head1 AUTHOR
1940
1941	debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1942	current is available at http://www.deepnet.cx/debbuild/.
1943
1944	=head1 BUGS
1945
1946	Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1947	fixing this.
1948
1949	Many macro expansions are unsupported or incompletely supported.
1950
1951	The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1952	environment variables and preprocessing that I haven't needed (yet).
1953
1954	Dcumentation, such as it is, will likely remain perpetually out of date.
1955
1956	%_topdir and the five "working" directories under %_topdir could arguably be created by
1957	debbuild. However, rpmbuild doesn't create these directories either.
1958
1959	=head1 SEE ALSO
1960
1961	rpm(8), rpmbuild(8), and pretty much any document describing how to write a .spec file.
