Refactor, replace deprecated setfsent() & C:o with setmntent()

Browse Source 
The setfsent() family of APIs was never standardized and on Linux only
GLIBC implement them.  We've tried to overcome this limitation, and to
support uClibc/uClibc-ng and musl libc, by providing replacements APIs
in helpers.c.

However, and since we want to support alternative /etc/fstab files, the
setmntent() family of APIs is more widespread and supports reading from
any fstab or mtab file.
