The list of strings is used quite frequently and we'd like to reuse
this simple structure for report selection support too. Make it part
of libdevmapper for general reuse throughout the code.
This also simplifies the LVM code a bit since we don't need to
include and manage lvm-types.h anymore (the string list was the
only structure defined there).
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.

Add thin and thin pool lv creation support to lvm library
This is Mohan's thinp patch, re-worked to include suggestions
from Zdenek and Mohan.
V2: Remove const lvm_lv_params_create_thin
Add const lvm_lv_params_skip_zero_get
V3: Changed get/set to use generic functions like current
property
V4: Corrected macro in properties.c
V5: Fixed a bug in liblvm/lvm_lv.c function lvm_lv_create.
incorrectly used pool instead of lv_name when doing the
find_lv_in_vg call.

Add a generic VG property function to lvm2app. Call the internal library
vg_get_property() function. Strings are dup'd internally.
Rework lvm_vg_get_property to return lvm_property_value and require caller
to check 'is_valid' flag. If !is_valid, the caller can check lvm_errno()
for the specific error.
Create a 'get_property' function, local to lvm2app, that factors out
most of the common code that copies the components of lvm_property_type
into lvm_property_value. This allows for a 1-line function for each
of the generic property functions exported by lvm2app.
