New structure lvm (used as an alias to cmd_context), new type definition lvm_t for the lvm handle. Added functions lvm_create, lvm_destroy and lvm_reload_config using the new handle. Modified test/api/test.c: Use new lvm.h header file and lvm_t handle. Removed lib/lvm2.h Author: Thomas Woerner <twoerner@redhat.com>
