libv4l2: Add plugin support to libv4l
A libv4l2 plugin will sit in between libv4l2 itself and the actual
/dev/video device node a fd refers to. It will be called each time
libv4l2 wants to do an operation (read/write/ioctl) on the actual
/dev/video node in question.
Changes before merge by Hans de Goede:
-export libv4l2_default_dev_ops for apps which directly use libv4lconvert
-use libv4l2_default_dev_ops in qv4l2 rather then defining our own there
-swap 1st 2 arguments to v4l2_plugin_cleanup to match v4l2_plugin_init order
-v4l2_plugin_init: return the address of the plugins devops, rather then
always returning the address of the default dev_ops and overriding the
individual default dev_ops with those of the plugin. The latter is a bad idea
when multiple /dev/video devices are opened in the same process space as
they may use different plugins
-use $LIBDIR/libv4l/plugins as pluginsdir instead of hardcoded
/usr/lib/libv4l/plugins

Start of 0.9.x devel cycle
v4l-utils follows the classic odd unstable / even stable release numbering,
this is the start of a new 0.9.x dev cycle leading to a 0.10.x (or maybe a
1.x) release. The plan for 0.9.x is to:
1) Keep the libv4l1 and libv4l2 ABI's compatible with 0.8.x
2) Change the libv4lconvert ABI, changing the soname to libv4lconvert.so.1
(from libv4lconvert.so.0), this is needed to be able to add plugin
support to libv4l2
3) Allow for somewhat more adventurous changes, until later in the 0.9.x
cycle, when things should stabilize again
Note WRT 2), that there is no promise of a stable libv4lconvert.so.1 ABI
until 0.10.0 is released!
