package kit: Add API for parsing resolvable expression strings

* Add BPackageInfo::ParseResolvableExpressionString().
* Add BPackageResolvableExpression constructor and SetTo() taking an
expression string.

BPackageResolvableExpression: Add Matches()

Checks if the given BPackageResolvable respectively the BPackageVersion
pair satisfies the expression.

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)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40405 a95241bf-73f2-0310-859d-f6bbb57e9c96

* rename AsString() methods to ToString() as suggested by Ingo
(following the naming used by other classes)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40356 a95241bf-73f2-0310-859d-f6bbb57e9c96

* made resolvable expression operator an enum instead of a string
* fixed a couple of copy'n'paste bugs during parsing of resolvable
expression lists (they were all added as 'requires')


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40353 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added some missing method implementations in BPackageResolvable
and BPackageResolvableExpression
* switched GetAsString() to a AsString() as that's much more convenient
and nothing can go wrong anyway


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40347 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added type-support to BPackageResolvable
* split BPackageResolvable, BPackageResolvableExpression
and BPackageVersion into separate files
