libselinux: rename hashtab functions
Browse files Browse the repository at this point in the history 
In commit d95bc8b ("libselinux: migrating hashtab from
policycoreutils") and commit 4a42050 ("libselinux: adapting hashtab
to libselinux"), the hashtab implementation was copied to libselinux.
Since the same functions exist in libsepol (e.g., hashtab_create,
hashtab_destroy, etc), a compilation error is raised when both libraries
are included statically.

Prefix the libselinux internal implementation with "selinux_".
