- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

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

Also add $FreeBSD$ to a few files to keep svn happy.

Change a char that is used as an index into an array into an unisgned char.
Add a missing new style function definition.

Fix type mismatch between char * and unsigned char *. C guarantees that
the values of the characters here are positive, so it's safe to index arrays
with them.

It was pointed out[0] that ctags(1) uses some potentially dangerous
system(3) calls where user-supplied data is used with no sanity
checking. Since ctags(1) is not setuid and is not likely to be used
in a privileged situation, this is not a big deal. However, the
fix is relatively easy and less ugly than the current code, let's be
safe. (I'm sure there are about 2^134 other system(3) calls like this
out there.)

ANSIify function definitions to avoid a warning.

Sort entries by locale collating order when -x is specified.

Create tags for typedefs, structs, unions and enums by default (imply the
-t option). Make a new option, -T, to revert to the old behaviour.

Avoid buffer overrun when identifies or filenames are extremely long.

Exit non-zero if the tags file cannot be opened.

remove __P

Remove unused #includes. lex -> Lex, yacc -> Yacc, ... Some .Nm to .Em
conversions. Sort #includes. Spelling. use errx() instead of err() when
explicit message is given.

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Use __FBSDID().

WARNS=2 fixup.

Add $FreeBSD$

MFC after: 2 weeks

Add braces to avoid ambigious else.

Tweaks to allow compiling -Wall (mostly adding "const" to char rcsid[]).

-Wall cleanup.

Add usage string. Typo in man page.

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

Add newline, closes bin/1433
