Split razor_package and razor_entry names into name and flags

split razor_property.name into name, flags, and type bitfields

Change list flags back to 8 bits instead of just 2

improve the list abstraction with "struct list_head" and "struct list"

both structs are actually just uint32_t's in disguise, using bitfields
to avoid the need for explicit bit operations, and using two type names
to hide the RAZOR_IMMEDIATE hack from the public API

Add a list abstraction for package/property lists

split array and hashtable code out into a new file

clean up some duplicated code around calls to add_to_property_pool

pad repo files with 0 bytes, not random memory

so you can do:
./razor import-yum
mv rawhide.repo rawhide.repo.orig
make
./razor import-yum
diff rawhide.repo.orig rawhide.repo

(doesn't work with system.repo at the moment...)
