Switch package file accessor classes to use BPositionIO * PackageFileHeap{Reader,Writer} as well as Package{Reader,Writer} and their implementation and super classes do now internally use a BPositionIO instead of a FD to access the package file. This provides more flexibility needed for features to come. * BPackageReader has already grown a new Init() version with a BPositionIO* parameter.

Separate notification from deletion in repository-handlers. * Add NotifyDone() to all repository-attribute handlers and invoke that to notify any listeners. * Unify deletion to a single implementation of Delete() in the base class. Before, the root handler for a repository didn't do that, but just triggered the notification.

Repository file format: group attributes of a package * Introduce new package attribute B_HPKG_ATTRIBUTE_ID_PACKAGE (valid only in a repository file) to group the attributes belonging to a package. * BRepositoryContentHandler: - No longer derive from BPackageContentHandler. - Add hooks HandlePackage() and HandlePackageDone() that bracket the attributes for a package. This is more explicit and robust than handlers having to guess when one package ended and the next began. * BRepositoryCache: Make use of BPackageInfoContentHandler. No need to duplicate the code for reading a package info from package info attributes.

ReaderImplBase: Verify that the attribute type matches ... the one expected for the respective attribute. Before it was possible that e.g. a uint was read and then interpreted as a const char*, if a string was expected for that attribute.

Package/repository file format: Add a minor version header field * Add minor_version to hpkg_header and hpkg_repo_header and make heap_compression uint16. * If the minor version of a package/repository file is greater than the current one unknown attributes are ignored without error. This allows introducing new harmless attributes without making the resulting files unreadable for older package kit versions.

packagefs: Add caching for the package file heap reader * ReaderImplBase: - Add virtual CreateCachedHeapReader() which can create a cached reader based on the given heap reader. - Rename HeapReader() to RawHeapReader() and add HeapReader() for the cached heap reader. - Add DetachHeapReader() to allow a clients to remove the heap reader(s) after deleting the ReaderImplBase object. * packagefs: - Add CachedDataReader class, which wraps a given BAbstractBufferedDataReader and provides caching for it using a VMCache. The implementation is based on the IOCache implementation. - Use CachedDataReader to wrap the heap reader. For file data that means they are cached twice -- in the heap reader cache and in the file cache -- but due to the heap reader using a VMCache as well, the pages will be recycled automatically anyway. For attribute data the cache should be very helpful, since they weren't cached at all before.

hpkg format: compress the whole heap Instead of handling compression for individual file/attribute data we do now compress the whole heap where they are stored. This significantly improves compression ratios. We still divide the uncompressed data into 64 KiB chunks and use a chunk offset array for the compressed chunks to allow for quick random access without too much overhead. The tradeoff is a limited possible compression ratio -- i.e. we won't be as good as tar.gz (though surprisingly with my test archives we did better than zip). The other package file sections (package attributes and TOC) are no longer compressed individually. Their uncompressed data are simply pushed onto the heap where the usual compression strategy applies. To simplify things the repository format has been changed in the same manner although it doesn't otherwise use the heap, since it only stores meta data. Due to the data compression having been exposed in public and private API, this change touches a lot of package kit using code, including packagefs and the boot loader packagefs support. The latter two haven't been tested yet. Moreover packagefs needs a new kind of cache so we avoid re-reading the same heap chunk for two different data items it contains.

They are invoked to bracket package file section, so the handler can discriminate which section the attributes belong to. HandleSectionStart() features a return parameter _handleSection, which allows to handler to pick which sections it wants to handle. * "package dump" does now print the section names.

Largish adjustments to PackagerReaderImpl and package attribute handling: * package attributes are now compatible with the low level attribute handling of other HPKG attributes (such that 'package dump' now shows package attributes, too) * dropped type names from hpkg format, the attributes were identified by IDs already and this simplifies the code considerably. Type names are now handled in BLowLevelPackageHandler only. * instead of rolling their own mechanism, high-level package attributes handling is now implemented via a corresonding set of AttributeHandler-subclasses * adjusted package writer to only write package attributes that are needed (empty ones are left out) git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40466 a95241bf-73f2-0310-859d-f6bbb57e9c96
