agp: Handle multiple devices more gracefully
Currently agp(4) effectively assumes that only one driver instance

alias of /dev/agpgart0 for compatibility.

pci: Don't try to read cfg registers of non-existing devices
Instead of returning 0xffs some controllers, such as Layerscape generate
an external exception when someone attempts to read any register
of config space of a non-existing device other than PCIR_VENDOR.
This causes a kernel panic.
Fix it by bailing during device enumeration if a device vendor register
returns invalid value. (0xffff)
Use this opportunity to replace some hardcoded values with a macro.
I believe that this change won't have any unintended side-effects since
it is safe to assume that vendor == 0xffff -> hdr_type == 0xffff.

ldconfig(8): check for no-args command line after options are parsed
Default action for ldconfig is specified as -R AKA 'append', and for
no-args (without options changing default actions), ldconfig should
append empty list of directories to current list. But because the check
was done before options were parsed out, presence of any option turned
off default rescan.
As result, innocently-looked commands like `ldconfig -v' were interpreted
as setting directory hints list to one specified on the command line,
i.e. empty.
Use bool.
Use local variables instead of static.
Remove non-functional debugging override of hints file path.
Use explicit exit() instead of return from main.
Minor style tweaks.
