* implement xmill compression for index read/write, tested
  with a remote repo
* start writing an option to force update of a repo

  new --until option to build command

  option, at any rate. who knows who might need them?
  we don't like to hide info. that's for wussies.

 ayrıca buildfarm'da arada bir aldığımız race conditional hatanın (NonType object has no attribute: split) sebebini de buldum ve fix ettim.. urllib'i alnından öpüyoruz..

* small fixes for fetcher (explicitly check perms for dest file)
* packagedb: method call fix

  skip downloading if sha1sum matches
* apply integrity check for index (fix #2340)
* some small improvements to fetcher
  * fix: check write access to destination file 
    if it already exists (permissions may change)
  

       let's not delete files like barbarians :)
* add sha1sum creation support to file ops, and endow
  index creation with this property, also start coding
  other index enhancements

       by finding which repo the guy is from
* fix: remove item from, dr, too

fixed now. it's too silly to explain.

  when a repo is removed
* fix: delete empty entries after removal of a repo

* fix: do not try to init dbenv unnecessarily

* fix: use itembyrepodb in sourcedb
* fix: make pkgtosrc db repo-aware 

is coming from another distribution (and just
what is a distribution here?) pending fix: we need a
global id for repositories (not user specified)
* fix: invalidate everything. goddamn it. (kidding)
* fix: itembyrepodb: has_key when repo given, needs guard 
statement, and fix typo in method name...

* fix: remove log files, too. due to a bug in bsddb3 we can't use dbremove

* fix: wrong msg in packagedb use

* fix: get rebuild-db to work again
* fix: note that LockedDBShelf doesn't return True if not equal to None (why
the hell???)
* __str__ function for Version

  degradation observed, scalable in the number of repos.
* generalize decode/encode method in dbshelve
* fix: user interface init must come first
* fix: do not try to read autoxml file if xmlfile_support not available
* various other small fixes

 Gerekli olmadığına inandığımız *.a dosyalarını paketlerin içine almayıp otomatik yaratılan ayrı bir pakete koyalım dedik..

 --create-static diye bir parametre ekledim. Şimdilik özellikle istenmediği sürece *-static paketleri oluşturulmuyor. Fakat depo'daki eksikleri düzelttikten sonra bunu öntanımlı seçenek haline getirip getirmemeyi tartışabiliriz.

  her seferinde yapılması gerekmeyen işleri __init__ içerisine taşı + build sisteminin relative destination dir'ler ile düzgün çalışmasını sağla.
