In HandleEntry() create the file/directory with sufficient permissions
for the user and set the archived permissions in HandleEntryDone(). This
makes sure child attributes and entries can be created.
* Match the attribute in a loop, use an attribute ID switch, do the
"seen" checks without the switch.
* Explicitly handle the case when encountering an unknown attribute.
* Use braces instead of brackets for lists.
* Semicolons and newlines separate items now. Remove handling for comma.
* Allow '\'' as quotation character.
* Remove assignment after variable name.
This should make the .PackageInfo format driver settings compatible, but
not vice versa. It is still stricter.
To avoid a clash with the regular version or an extra attribute level we
use the "package:provides.compatible" package attribute instead of
"package:version.major".
* The version string pattern is now:
<major>[.<minor>[.<micro>]][-<pre>][-<release>]
* Introduce B_HPKG_ATTRIBUTE_ID_PACKAGE_VERSION_PRE_RELEASE package
attribute.
* Add "preRelease" field to BPackageVersionData.
* Add "preRelease" property to BPackageVersion and packagefs's Version.
* Adjust package reader and writer code accordingly.
* Add utility class AutoPackageAttributes and AttributeCookie subclass
AutoPackageAttributeCookie.
* UnpackingAttributeCookie::Open() does now try to create a
AutoPackageAttributeCookie, when it doesn't find the attribute in the
PackageNode.
* Adjust UnpackingAttributeDirectoryCookie to also list auto-generated
attributes.
Currently the only supported attribute is "SYS:PACKAGE", which is the
file name of the package containing the node.
Added trivial implementation for AttributeCookie::Close() and
AttributeDirectoryCookie::Close() and removed the identical Close()
implementations in derived classes.
* Add ResolvableFamily and DependencyFamily classes for grouping equally
named resolvables/dependencies.
* Add hash tables to PackageFSRoot to track resolvables and
dependencies. That is done in {Add,Remove}Package.
* Resolvable does now have a list of Dependency objects, the ones it
satisfies.
* PackageLinksListener: Rename methods from *Directory*() to *Node*()
and change parameter to Node*. Also add a *Changed() method.
* PackageLinkDirectory: Update only when necessary and what is necessary
(currently only the self link).
