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.

Use the newer and more robust libutil provided function
util_sys_get_dev_addr() to identify a device address for any former user
of u2s_getbusid().

dasdview and libdasd deal with DASD bus ids and should use a definition
for the size. libu2s already provides a definition, which is used by
dasdview. However, the size of 32 is a bit much and the definition
should be part of libdasd.
Including the terminating null byte ('\0') and considering a DASD bus id
length of 8 characters (e.g. 0.0.4711), this leads to a size of 9.
Provide such a definition via libdasd and update any user.

Don't rely on rather arbitrary values for the string buffer size of
different sysfs paths. Instead use util_path_sysfs(), which allocates
the exact amount of memory necessary for a certain path string.
As these path strings are dynamically constructed, potential buffer
overflows can hereby be avoided and make the library functions more
robust.
