Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

Drop ed(1) "crypto"

You should not be using DES. You should not have been using DES for the
past 30 years.

The ed DES-CBC scheme lacked several desirable properties of a sealed
document system, even ignoring DES itself. In particular, it did not
provide the "integrity" cryptographic property (detection of tampering), and
it treated ASCII passwords as 64-bit keys (instead of using a KDF like
scrypt or PBKDF2).

Some general approaches ed(1) users might consider to replace the removed
DES mode:

1. Full disk encryption with something like AES-XTS. This is easy to
conceptualize, design, and implement, and it provides confidentiality for
data at rest. Like CBC, it lacks tampering protection. Examples include
GELI, LUKS, FileVault2.

2. Encrypted overlay ("stackable") filesystems (EncFS, PEFS?, CryptoFS,
others).

3. Native encryption at the filesystem layer. Ext4/F2FS, ZFS, APFS, and
NTFS all have some flavor of this.

4. Storing your files unencrypted. It's not like DES was doing you much
good.

If you have DES-CBC scrambled files produced by ed(1) prior to this change,
you may decrypt them with:

openssl des-cbc -d -iv 0 -K <key in hex> -in <inputfile> -out <plaintext>

Close the input FILE * in read_file() and the output FILE * in write_file()
if read_stream() or write_stream() fails to avoid leaking the FILE.

More -Wmissing-variable-declarations fixes.

In addition to adding `static' where possible:

- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

Fix warnings found by -Wmising-variable-declarations.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.

- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.

Fix some obtuse fprintf tricks in bin/ed.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

Consistently use __FBSDID

o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.
o gc some #ifdef sun ... #endif code

Approved by: arch@, new style(9)

o Correctly define rcsid.
o Add consts where appropriate.
o Rename some variables that were shadowing global declarations.
o Remove register storage-classes.
o Make errmsg a const, so we can just set error messages instead
of using sprintf/strcpy.
o Set WARNS=2

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

-Wall cleaning.

Output line count to stdout. Complies to POSIX.2.

Reviewed by: joerg

You will find enclosed some changes to make gcc -Wall more happy in
/usr/src/bin. Note that some patches are still needed in that directory.

I (Joerg) finished most of Philippe's cleanup. /bin/sh will still
need *allot* of work, however.
