06b8fee542 Allow $DM_DEV_DIR envvar to override default of "/dev". 
* dmsetup/dmsetup.c (DEV_PATH): Remove definition.
(parse_loop_device_name): Add parameter: dev_dir.
Declare the "dev" parameter to be "const".
Use dev_dir, not DEV_PATH.  Handle the case in which dev_dir
does not end in a "/".
(_get_abspath): Declare "path" parameter "const", to match.
(_process_losetup_switches): Add parameter: dev_dir.
Pass dev_dir to parse_loop_device_name.
(_process_switches): Add parameter: dev_dir.
Pass dev_dir to _process_losetup_switches.
(main): Set dev_dir from the DM_DEV_DIR envvar, else to "/dev".
Call dm_set_dev_dir.
* lib/libdm-common.c (dm_set_dev_dir): Rewrite to be careful
about boundary conditions, now that dev_dir may be tainted.
* man/dmsetup.8: Mention $DM_DEV_DIR.

4ab5b20654 Arrange for "make clean" to remove the symlink, too. 
* make.tmpl.in ($(VERSIONED_SHLIB)): Move rule to...
* lib/Makefile.in ($(VERSIONED_SHLIB)): ...here, removing the
$(interface)/ prefix.

78ecdf8d65 Create a symlink, e.g., libdevmapper.so.1.02, in the build dir, 
alongside the .so file.  This helps build dynamically linked LVM.

* lib/Makefile.in (VERSIONED_SHLIB): Define.
* make.tmpl.in (TARGETS): Append $(VERSIONED_SHLIB).
($(VERSIONED_SHLIB)): New rule.

5469414bf8 Timeout event implementation: 
The daemon side of this is mostly the same as the patch I sent out.  To select
a timeout period different than the default and to get the timeout period,
I added two library calls, dm_set_event_timeout() and dm_get_event_timeout().
If people are against them, the other option is to tack extra arguments onto
dm_regiser_for_event() and dm_get_registered_device().  I also added a
-t option to dmevent, so people can try out timeouts.
