Fix behaviour of 'package_repo update':

* Instead of copying over the repository info from the source
repository, we need to read the repository info from a repository
info file corresponding to the target repository. Among other
problems, copying over the repository info from the source repo
put the wrong repository URL into the new repository, which in
turn caused the package resolution done by Haiku's build system to
fail (it tried to download packages from the wrong URL).
Additionally, I have updated the incorrect repository on the server, so
building Haiku-x86 should work again.

Add command 'update' to package_repo.

* 'update' takes an existing repository and a package list file and then
creates a new repository from that, avoiding expensive
checksum-recomputations where possible

Implemented repository writing:
* fleshed out RepositoryWriterImpl
* renamed BRepositoryHeader to BRepositoryInfo (in accordance with
BPackageInfo)
* adjusted BRepositoryInfo to be able to parse itself from a
driver_settings file
* added package_repo binary (only 'create' works as of yet)
