config: default option for enable-dri3 is not implemented
The first symptom is the help text:
--enable-dri3 Build XCB DRI3 Extension (default: "$sendfds")
The implementation variable $sendfds leaked into the user interface.
Testing the various user inputs:
<nothing> DRI3 is enabled PASS
--enable-dri3 DRI3 is enabled PASS
--enable-dri3=yes DRI3 is enabled PASS
--enable-dri3=no DRI3 is disabled PASS
--disable-dri3 DRI3 is disabled PASS
--enable-dri3=$sendfds DRI3 is disabled FAIL
This patch implements the usual idiom for features that are enabled by
default if the various conditions are met (sendfds is available).
New help text:
--enable-dri3 Build XCB DRI3 Extension (default: auto)
With the additional user input:
--enable-dri3=auto
which is equivalent to providing no input at all.
