Remove dead code
At last unique identifier is now pkgname
Finish changing uniqueid to pkgname
indent
Drop incremental support for pkg update

This was wrong and prevented remote packages from having 2 version of
the same package in the repo
speed up a bit by updating the processbar less often
Adapt use message to the new update system
Don't know how and why c was looked for as a wildcard...
Fix sql error
No need to walk twice on the buffer for updates

This also allows to mmap read-only

Idea from des@
Significant update performance update playing with page_size and cache_size
Dynamically get the proper pagesize
Update to sqlite 3.8.7
As stated by upstream disabling thread safety in sqlite improve perfs
Drop unique key on packages (and fix the one on dependencies)

This also speeds up a bit update and allowing multiple package with the
same name
Update to the new website for audit
