[PATCH v2 RESEND 0/5] Support autoloading of non-PCI drivers

From: Thierry Reding <treding at nvidia.com>

This series introduces a new configuration section, OutputClass, which
can be used to match an output device against a set of attributes and
pass in additional configuration. The idea is that each DDX module for
output drivers can ship configuration snippets that give a hint as to
what devices they support.

Patch 1 modifies xf86MatchDriverFromFiles() to behave more like the
other driver enumeration functions. This makes the code in subsequent
patches simpler.

Patch 2 is preparatory work to store the name of a device's kernel
driver for later use.

Patch 3 adds the new OutputClass section that for now only supports
matching by kernel driver name and providing the name of the DDX module
to load for a matching device.

Patch 4 in this series makes use of these configuration snippets to
auto-load drivers for a particular device.

Patch 5 makes an error message more readable and consistent with code
introduced in an earlier patch.

Changes in v2:
- address review comments from Aaron Plattner:
  - drivers matched by OutputClass take precedence over other drivers
  - fix typos in manpage, start sentences on new lines
  - make error messages more readable
