After the re-org of the atapi code, it might not be intuitive for a
reader of the code to understand why we're inserting a 'media not
present' state between cd changes.

Some commands are supposed to report a Not Ready Condition (i.e. they require
a medium to be present in order to execute successfully). Instead of
duplicating the check in each command implementation, let's add a flag and
check it before calling the command.
This patch only converts existing checks, it does not introduce new checks for
any of the other commands that can/should report a Not Ready Condition.

The disk size can only change when the medium is changed, and the change
callback takes care of updating s->nb_sectors in this case.

In preparation for a table of function pointers, factor each command out from
ide_atapi_cmd() into its own function.

Besides moving code, this patch only fixes some whitespace issues in the moved
code and makes all functions in atapi.c static which can be static.
