FTS_LOGICAL sets FTS_NOCHDIR; otherwise have to save full path each time
it indirects through a symlink. Instead of doing getwd/chdir's, open an fd
and do an fchdir; wastes an fd per open stream. Fix ftschildren() -- redid
most of the directory handling logic, special case first node in case it gets
called before ftsread does a chdir to the subdirectory. Minor changes to path
handling in fts_build.

redo the way the initial linked list of "roots" is set up; broke
if you called ftsread multiple times in the same program.

add FTS_XDEV; don't cross mount points

change the names from foo to fts_foo

put pathnames into netdb.h

document how to reparse arguments

fix the resolver addresses to be as before if an error occurs

new calling convention for strsep, takes char **

don't do a putchar on unknown inode...

simplify rounding, KNF
