Add a new API that allows the caller to skip any forced probing, which
may require slow i2c to a remote display, and only report the currently
active mode and encoder for a Connector. This is often the information
of interest and is much, much faster than re-retrieving the link status
and EDIDs, e.g. if the caller only wishes to count the number of active
outputs.
v2: Fix error path to avoid double free after a failed GETCONNECTOR
ioctl.
v3: Daniel strongly disapproved of my disjoint in behaviour between
GetConnector and GetConnectorCurrent, and considering how best to make a
drop in replacement for drmmode_output_init() convinced me keeping the
API as consistent as possible was the right approach.
v4: Avoid probing on the second calls to GETCONNECTOR for unconnected
outputs.

... minus test/ttmtest. The latter is not really hooked up with the
actual build.
This will give us 66 warnings on a distribution build of which
- 12 -Wunused-variable
- 11 -Wunused-function
- 19 -Wmissing-prototypes
and a few -Wswitch-enum, -Wtype-limits etc.
Adding the CFLAGS gives some exposure to these so that we can fix them.

Use same names as the kernel, makes it easier to identify
connectors in the common case.

Install test programs is useful in cross compilation case. By default
the behavior is the same and test programs aren't installed in $bindir.
If --enable-install-test-programs is set then test programs are
installed in $bindir.

Add mode setting files to libdrm, including xf86drmMode.* and the new
drm_mode.h header. Also add a couple of tests to sanity check the
kernel interfaces and update code to support them.
