Unify/cleanup usage of hash_set/unset_mem by tunnels (VPP-1117)
Move the functions hash_set_key_copy() and hash_unset_key_free() which are dupilicated in various tunnel support code modules to hash.h as hash_set_mem_alloc() and hash_unset_mem_free() to be used by all. Change-Id: I40723cabe29072ab7feb1804c221f28606d8e4fe Signed-off-by: John Lo <loj@cisco.com> (cherry picked from commit e6bfeab1c352ae73a19361c038e2a06a58c035db)
