Standalone library for fts functions.
From man 3 fts: The fts functions are provided for traversing file
hierarchies. A simple overview is that the fts_open() function returns
a "handle" on a file hierarchy, which is then supplied to the other fts
functions. The function fts_read() returns a pointer to a structure
describing one of the files in the file hierarchy. The function
fts_children() returns a pointer to a linked list of structures, each
of which describes one of the files contained in a directory in the
hierarchy. fts conforms to 4.4BSD.
fts is usually provided by the system's libc, as glibc and uClibc do. However, musl does not and hence the need for a standalone version. This code was adopted from OpenBSD 5.7 and modified slightly to build in Linux.
