Replace usages of B_FILE_NOT_FOUND in non-BeOS-API code.

B_FILE_NOT_FOUND was deprecated in BeOS R5 in favor of B_ENTRY_NOT_FOUND,
but it remained in Haiku and was never removed even conditionally, so
we have accumulated a number of usages of it.

This commit changes all the usages of it in new code, applications,
or anything else that BeOS applications will otherwise never see,
and so should be relatively safe.

PackageKit: HPKR BMessage Format Fix

Some older repositories are having problems because
they are configured with a `url` (identifier) form
that is not actually a well-formed URL. This caused
problems when it was then interpreted as the
base-url because it did not start with "http". I
have changed this so that the base-url is not
derived from the url and can be missing.

Resolves #16149

Style fix.

Fix #10610.

Added missing initializer for fContext in PackageInfoErrorListener whose
absence was leading to crashes when generating the error string.

BRepositoryBuilder: Add constructor for pre-init'ed repository

Refactor reusable pkgman code into libpackage

* Move RepositoryBuilder class to libpackage and add B* prefix to name.
* Pull BPackageManager class out of PackageManager and move to
libpackage. The base class is customizable via three handler objects
responsible for transaction handling, request execution, respectively
user interaction.
* Reorganize _ApplyPackageChanges(): Now we first prepare the
transactions for all affected installation locations (downloading
files etc.) and then commit them.
