Add library functions that allow to communicate with z/OSMF REST services
using libcurl.
Following three functions are added:
lzds_rest_get_enq()
to obtain an ENQ that will mark a dataset as in use to z/OS until
it is released again
lzds_rest_release_enq()
to release an ENQ and mark a dataset as no longer in use to z/OS
lzds_rest_ping()
to ping a z/OSMF REST server to check if it accessible
or to refresh an ENQ and prevent it from a timeout after 10 minutes

Reading DASD specific sysfs attributes should be collected in one
library. Move get_host_access_count() to libdasd/dasd_sys.
Remove the old implementation and update any user accordingly.
Also, fix the build order for zdsfs.

Enable zdsfs to access datasets that were created after zdsfs was
mounted without the need to remount zdsfs.
This is done by re-reading the VTOC with every readdir system call.
To ensure a consistent VTOC state the DASD device is reserved for
every VTOC read and released afterwards.

Since now util_list_new() internally fails for out-of-memory situations,
we can also remove some NULL pointer checks.
