MFC r238780,r238948: find: Implement real -ignore_readdir_race.

If -ignore_readdir_race is present, [ENOENT] errors caused by deleting a
file after find has read its name from a directory are ignored.

Formerly, -ignore_readdir_race did nothing.

MFC r240973: find: Do not pass fd to save current directory to child
processes.

This removes one of the two wrongly passed file descriptors. The other one
appears to be from fts(3).

find: Exit if there is an unknown option.

Ignoring the parameter with the unknown options is unlikely to be what was
intended.

Example:
find -n .

Note that things like
find -n
already caused an exit, equivalent to "find" by itself.

Remove the advertising clause from UCB copyrighted files in usr.bin. This

Move SCCS tags to comments as they were already #if 0'ed.

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

Fix SYNOPSIS and usage().

Fix all WARNS. Checked with "make WARNS=9". Remove unused file.

Fix SCM IDs.

Remove __P().

1) Remove -Wall from Makefile.
2) WARNs fixes (rename option to lookup_option to avoid shadowing, rename
argv to argv1 to avoid shadowing, const stuff, prototypes, __unused).
3) Remove "register"s.

Implement the following options and primaries:

-E Interpret regular expressions followed by -regex and -iregex op-
tions as extended (modern) regular expressions rather than basic
regular expressions (BRE's). The re_format(7) manual page fully
describes both formats.

-iname pattern
Like -name, but the match is case insensitive.

-ipath pattern
Like -path, but the match is case insensitive.

-regex pattern
True if the whole path of the file matches pattern using regular
expression. To match a file named ``./foo/xyzzy'', you can use
the regular expression ``.*/[xyz]*'' or ``.*/foo/.*'', but not
``xyzzy'' or ``/foo/''.

-iregex pattern
Like -regex, but the match is case insensitive.

These are meant to be compatible with other find(1) implementations
such as GNU's or NetBSD's except regexp library differences.

This patch adds the -mindepth and -maxdepth options to find(1), which
behave as in GNU find (and of course as described in the manual page
diff included). I think these options would be useful for some people.

Some missing $FreeBSD$ tags are also added.

The patch was slightly modified (send-pr mangling of TABS).

Fixed my English fixes.

Fixed disorder and and usage message. Improved English.

Broken in: previous commit

Added a sort option to find(1).

The sort option make it possible to build the locate
database without large (usually 20-100MB) temp files.

Eliminate a variable that is set but never used.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Merge from Lite2 - use new getvfsbyname() and related changes.
understand whiteouts (FTS_W from fts()).

Localize it

Remove trailing whitespace.
