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.

package kit: some fixes for multi-version support

* Use enums/constants/functions instead of preprocessor macros.
* Missing include in PackageInfoAttributeValue.h.
* PackageReaderImpl::Init(): Check version before header size and
return B_MISMATCHED_VALUES instead of B_BAD_DATA, if the version
doesn't match. This allows callers to determine the condition and
try a reader for a different version. A more flexible interface for
that case would be nice, but since we want to support the old package
version only temporarily, the current solution should be good enough.
