lint and KNF

weren't checking high enough in the tree for cycles; get rid of the
savelink stuff and just add another pointer field to the FTSENT structure

prototype internal routines

set level before calling fts_stat during fts_open, cycle detection uses it

fts_load no longer has any return value

don't set XDEV dev_t until have stat'd the root of the tree

change to return to starting node before postorder return of root
nodes; move chdir calls from fts_load to fts_read. Nasty.

#define root and root's parent fts_level values in <fts.h>
delete hack to make root DNE error FTS_ERR instead of FTS_NS, the usual return

rework to set errno on fts_info error cases, return names from unsearchable
directories

ANSI; #ifdef out code to delete trailing slashes from user path

wasn't resetting errno for fts_children call of fts_build for
unsearchable directories

use macros to set/read options
rename functions/fields to POSIX names
make comments consistently use capital letters
get rid of global variable stream and pass around current stream pointer
don't cast free to void
add FTS__NOINSTR flag, instead of using 0 as "no user instructions"
allow fts_children call for FTS_{D,DNR,DNX} instead of just FTS_D
change fts_build so that fts_children can read FTS_DNX directories
make fts_stat return FTS_NS on stat failure, not FTS_ERR
make fts_stat unset errno on FTS_{NS,SLNONE} conditions

don't bother stating the root paths, if FTS_NOSTAT set

delete FTS_MULTIPLE

do post-order visit if FTS_SKIP or FTS_XDEV apply to preorder visit

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

remove permissions checking code, let the kernel do it. This means
that FTS_{DNR,DNX} are not returned until post-order directory visit.

add fchdir; reduce number of cd's, do all cd's in fts_build
