PackageKit: use the correct kernel headers.

The debug build of the packagefs kernel addon failed because user_memcpy had no type.
Using the correct headers for user_memcpy and IS_USER_ADDRESS fixed the issue.

PackageKit: tweak classes used by packagefs to write to user buffers.

when compiled in kernel mode, BMemoryIO::WriteAt() and BBufferDataReader::ReadData()
now check the buffer to write to, and eventually call user_memcpy() instead of memcpy().

Remove BPackageKit::BDataOutput

Use BDataIO instead.

Style fixes, no functional changes

* Pointed out by Axel and Ingo.

Fix more issues detected by gcc4 compiler:

More ssize_t/status_t mixup.

Move ZlibDecompressor to libshared

* This will be used to implement compressed http streams
* Remove the custom BDataOutput class, and use BDataIO instead, for
easier integration with existing code.

Some *DataReader improvements

* BFDDataReader: Add SetFD().
* BBufferDataReader: Derive from BAbstractBufferedDataReader.

package kit: Add BAbstractBufferedDataReader

It doesn't do much in terms of buffering, but defines an interface
buffered readers can implement, namely the additional
ReadDataToOutput() which currently BPackageDataReader specifies.

Split package kit DataReader.cpp

Pull AttributeDataReader and FDDataReader implementations out of
DataReader.cpp into own source files. Thus we can avoid dependencies
(e.g. to fs_attr code) we don't need/want.

Fixed host build issues/warnings

Fixed host build issues/warnings

Refactored hpkg implementation to provide some separation between
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

More work on package kit:
* added class BPackageInfo, which contains packaging attributes of
a package (the values relevant for package management)
* implemented parser (mostly) for reading a BPackageInfo from a config
file (.PackageInfo) in order to pass them on to the PackageWriter
when creating a package
* pulled hpkg-related stuff from bin/package into the package kit
* adjusted packagefs-Volume to skip .PackageInfo files when populating
the mountpoint, as those files shouldn't appear as part of an
activated package
