package kit: Add pre-uninstall scripts feature.

Just like post-install scripts which run shortly after a package is
installed, pre-uninstall scripts are run just before a package is
removed. Implements enhancement #13427

* Fix script exit code handling vs script launch errors.
* Bump package and repo file version numbers due to new attribute,
unfortunately makes new .hpkg files not backwards compatible.
* Add pre-uninstall functionality, mostly cloning the post-install
except in a few places.
* Discover that _RunQueuedScripts() is never called, a future TODO:?
* Update package documentation for pre-uninstall scripts, and use of
the boot/post-install directory.

hpkg format: Add attributes for declaring settings files

Global and user settings files can be declared. For global ones an
update policy can be specified. If not specified, the settings file is
not included in the package, but created by the program (or user) later.
If an update type is specified, it defines what to do with the settings
file when updating the package to a newer version.

User settings files are never included in the package; they are always
created by the program or the user. If the package contains a template/
default settings file, it can be declared, but for informative purposes
only.

* 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

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.
