eaeb33abd4 liblvm: Save off and restore umask values
lvm has a default umask value in the config file that defaults
to 0077 which lvm changes to during normal operation.  This
causes a problem when the code is used as a library with
liblvm as it is changing the umask for the process.  This
patch saves off the current umask, sets to what is specified
in the config file and restores it what it was on library
function call exit.

The user is now free to change the umask in their application at
anytime including between library calls.

This fix address BZ:
https://bugzilla.redhat.com/show_bug.cgi?id=1012113

Tested by setting umask to 0777 and running the python unit
test and verifying that umask is still same value as expected
at the test completion and with a successful run.

fe5b538c14 lvm2app: Reset buffer after retrieving error message
The error buffer will stack error messages which is fine.  However,
once you retrieve the error messages it doesn't make sense to keep
appending for each additional error message when running in the
context of a library call.

This patch clears and resets the buffer after the user retrieves
the error message.

50db109e20 liblvm: Moved additional pv resize code
The pv resize code required that a lvm_vg_write be done
to commit the change.  When the method to add the ability
to list all PVs, including ones that are not assocated with
a VG we had no way for the user to make the change persistent.
Thus additional resize code was move and now liblvm calls into
a resize function that does indeed write the changes out, thus
not requiring the user to explicitly write out he changes.

f65dd341a5 locking: Make it possible to pass down an LV to activation code.
Previously, we have relied on UUIDs alone, and on lvmcache to make getting a
"new copy" of VG metadata fast. If the code which triggers the activation has
the correct VG metadata at hand (the version which is currently on disk), it can
now hand it to the activation code directly.

386886f71c config: refer to config nodes using assigned IDs
For example, the old call and reference:

  find_config_tree_str(cmd, "devices/dir", DEFAULT_DEV_DIR)

...now becomes:

  find_config_tree_str(cmd, devices_dir_CFG)

So we're referring to the named configuration ID instead
of passing the configuration path and the default value
is taken from central config definition in config_settings.h
automatically.
