addmntent: Remove unbounded alloca usage from getmntent [BZ#27083]
The addmntent function replicates elements of struct mnt on stack using alloca, which is unsafe. Put characters directly into the stream, escaping them as they're being written out. Also add a test to check all escaped characters with addmntent and getmntent.
