Jonas Ådahl 4ebc55f2b3 Make libmutter and friends parallel installable 
In order to minimize the amount of breakage, while at the same time
making it easier to make backward incompatible changes needed to
continue turning libmutter into a capable Wayland compositor, make the
libmutter and friends (libmutter-clutter, libmutter-cogl*) parallel
installable by adding a version number to the name. This changes
various filenames, for example what previously was libmutter.so is now
libmutter-0.so (assuming the version for now is 0), and
libmutter-clutter-1.0.so is now libmutter-clutter-0.so. The pkg-config
filenames and GObject introspection has been renamed to reflect this as
well.

This enables a downstream compositor rely on a specific version of the
libmutter API, while gracefully handling API/ABI changes by having to
update to the new version at their own pace.

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.
#
# Possible status values are: git, snapshot or release
