	Some dependency resolver enhancements and bug fixes.

	* src/pkgbase.h (pkgXmlNode::GetContainerAttribute): New method;
	declare it.

	* src/pkgdeps.cpp (pkgXmlNode::GetContainerAttribute): Implement it;
	it is used to retrieve package name attributes from the containing
	'package' element, when given a pointer to a 'release' element by...
	(assert_unmatched, assert_installed): ...these new static functions.
	(pkgXmlDocument::Schedule): Use them to reconstruct and register
	dependency reference data for previously installed packages which are
	no longer included in the distribution manifest.

	Improve scheduling of package processing requests.

	* src/pkgexec.cpp (pkgXmlDocument::Schedule): Inspect entire `actions'

	Work around an autoconf bug (reported by Stefano Sabatini).

	* Makefile.in (VPATH): Use @top_srcdir@ instead of ${srcdir}; current
	autoconf incorrectly elides references to @srcdir@ and ${srcdir} when
	substituting within a VPATH specification for building `in-source'.
	Also, prefer colons to blanks as path name separators, for improved
	portability to non-GNU implementations of make; (recommendation by

	Include alias search, when matching component package name.

	* src/keyword.c (has_keyword): Rearrange argument declarations for
	more natural order; update all callers accordingly.  Simplify; compare

	the look-up name, after stripping, matches any specified alias name
	for the containing package.

	the installed package image.

	* src/pkgkeys.h (defaults_key): New key; declare it.
	* src/pkgkeys.c: Some cosmetic formatting (tabulation) adjustments.
	(defaults_key): Implement it; it refers to the `defaults.xml' file.

	* src/climain.cpp (climain): Check `profile_key' for accessibility of
	the `profile.xml' file; if [! R_OK] emit a diagnostic warning, fall

	Add preliminary support for future `-reinstall' option.

	* src/pkgexec.cpp (pkgActionItem::Execute) [ACTION_INSTALL]: Force

	variable; it stores a pointer to a dynamically allocated local copy of
	the invariant `version' argument, to facilitate correct parsing.
	(pkgVersionInfo::build_string): Likewise; it provides similar handling
	for the invariant `build' argument.
	(pkgVersionInfo::Free): New private inline method; it provides a NULL
