Instead of having a null pointer, use a dummy array which just
says the array is empty. This helps in multiple places of the code
which would otherwise need explicitly need to check first if the
array exists. This has been cause of multiple seg.faults in the
past as the array check is easily omitted.
This also removes (or fixes) all existing checks accordingly.
previously they might have been skipped on certain situations.
this also fixes some other reverse dependency enforcements and
implements new "pending" state for locked name.
this way we never change cwd, and relative filenames are always
parsed consistently. this also helps filename construction in many
places. this patch also changes '--root' to override location of
all configuration to be in the new root. previously it depended
on the file which one was used.
apk --help will list the generic options only and give a list of commands
To get the details for a spefic command, 'apk command --help' should be used.

This will also fix a bug that left an empty file in destination dir when
source file did not exist in repository.
There are still issues with paths longer than 255 chars.
