2360ce3551 cleanup: Use lv_is_ macros.
Use lv_is_* macros throughout the code base, introducing
lv_is_pvmove, lv_is_locked, lv_is_converting and lv_is_merging.

lv_is_mirror_type no longer includes pvmove.

13fb02ff1f cleanup: ignore vg_name in /lib
Since  vg_name inside /lib function has already been ignored mostly
except for a few debug prints - make it and official internal API
feature.

vg_name is used only in  /tools while the VG is not yet openned,
and when  lvresize/lvcreate /lib function is called with VG pointer
already being used, then vg_name becomes irrelevant (it's not been
validated anyway).

So any internal user of lvcreate_params and lvresize_params does not
need to set vg_name pointer and may leave it NULL.

998af1a4fb Misc: Change name of lvcreate_params field - s/create_thin_pool/create_pool/
In preparation for other segment types that create and use "pools", we
s/create_thin_pool/create_pool/.  This way it is not awkward when creating
a cachepool, for example, to use "create_thin_pool".

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.
