Robert Bragg b380fed23d Make stub winsys into a proper winsys backend 
Instead of the stub winsys being a special case set of #ifdef'd code
used when COGL_HAS_FULL_WINSYS wasn't defined, the stub winsys now
implements a CoglWinsysVtable like all other winsys backends (it's just
that everything is a NOP). This way we can get rid of the
COGL_HAS_FULL_WINSYS define and also the stub winsys can be runtime
selected whereas before it was incompatible with all other winsys
backends.

dnl XXX: If you are making a release then you need to check these
dnl sections:
dnl » API versions
dnl (the pretty numbers that the users see)
dnl
dnl » Interface version details for libtool
dnl (the shared library versioning information)
dnl
dnl » Source code release status
dnl (mark the source code as being part of a "release" or from "git")

dnl Interface version details for libtool
dnl ================================================================
# Note: we don't automatically deduce the libtool version info from
# the pretty version number that users sees. This is because we want
# to update the pretty version number before making a release since it
# can affect the name of our pkg-config file and the naming or
# location of other installed files which we want to be able to verify
# as correct well before making a release.
#
# For reference on how the various numbers should be updated at
# release time these rules are adapted from the libtool info pages:
#
# 1. Update the version information only immediately before a public
# release.
#
# 2. If the library source code has changed at all since the last
# update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
#
# 3. If any interfaces have been added, removed, or changed since the
# last update, increment CURRENT, and set REVISION to 0.
#
# 4. If any interfaces have been added since the last public release,
# then increment AGE.
#
# 5. If any interfaces have been removed since the last public release,
# then set AGE to 0.

# Finally we explicitly track when we are building development source
# from Git vs building source corresponding to a release. As with the
# libtool version info we don't automatically derive this from the
# pretty version number because we want to test the results of
# updating the version number in advance of a release.
