* Introduce BPackageWriterParameters which comprises all parameters
for package creation, currently flags and compression level. Such an
object can be passed to BPackageWriter::Init() and is passed on to
PackageWriterImpl and WriterImplBase.
* PackageFileHeapWriter: Add compressionLevel property and pass the
value on to ZlibCompressor.
* package add/create: Add options -0 ... -9 to specify the compression
level to be used.
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.
* 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.
* ... to avoid confusion with the preRelease property. It's also called
"revision" in the HaikuPorts recipes.
* Update libsolv package. Was necessary due to the BPackageVersion
change, but also includes a few more changes.
The attribute is intended for simplifying package building. The
package's install path will be used for the package's .self package
symlink, allowing installation to a temporary directory when building
the package.
Add flags parameter to BPackageWriter::Init() (and the private
implementation classes) to indicate that an existing package file shall
be updated instead of created. Currently that always happens in-place.
* 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.
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)

types and defines of HPKG
* added header, magic and version for haiku repository format
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40370 a95241bf-73f2-0310-859d-f6bbb57e9c96
* added kernel-compatible datatypes for reading package info attribute
values (PackageInfoAttributeValue.h) - these will be used at a later
stage by the package-fs to transport those attributes to userland
when asked to do so (by ioctl)
* implemented parsing of package info attributes in PackageReaderImpl
* added support for compressed package attribute section to
PackageReaderImpl
* completed the writing of package info attributes in PackageWriterImpl
and fixed a couple of bugs exposed by parsing
* adjusted 'package list' to show the package info attributes as they
are found
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40354 a95241bf-73f2-0310-859d-f6bbb57e9c96
* added my own copyright to a couple of files that I changed

public and private API (still far from ideal, but a start):
* moved several HPKG-classes into the public namespace BPackageKit::HPKG
* added fImpl-wrappers around PackageReader and PackageWriter to hide
most of the gory details
* adjusted 'package'-binary and packagefs accordingly
