MFC r299524

Use strlcpy() instead of strncpy() when copying the encoding value
to ensure that the destination is NUL terminated. Length truncation
of one more character should not be an issue since encoding values
that long are not supported by libc. The destination string is
treated as a NUL terminated string, but it is only passed to strcmp()
for comparison to a set of shorter, fixed length strings, so this
is not a serious problem.

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

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

ANSIfy almost all applications that use WARNS=6.

I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.

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

Make mklocale work again, now that fwrite()'s return codes are different.

getopt(3) returns -1, not EOF.

Make <runefile.h> internal to libc.

Suggested by: phantom

Make the format of LC_CTYPE files architecture independent by
introducing the disk formats for _RuneLocale and friends.

The disk formats do not have (useless) pointers and have 32-bit
quantities instead of rune_t and long. (htonl(3) only works
with 32-bit quantities, so there's no loss).

Bootstrap mklocale(1) when necessary. (Bootstrapping from 4.x
would be trivial (verified), but we no longer provide pre-5.3
source upgrades and this is the first commit to actually break
it.)

Use <runetype.h> instead of <rune.h> since the latter is going away.

Remove explicit support for generating LC_CTYPE data files that specify
the obsolete "UTF2" encoding.

Prefix the names of members of _RuneLocale and its sub-structures
with ``__'' to avoid polluting the namespace. This doesn't change the
documented rune interface at all, but breaks applications that accessed
_RuneLocale directly.

Add gb2312 encoding.

Allow GB18030 locale

Bump WARNS to 6. Add usage(). Use provided xmalloc() instead of malloc().
Use err().

Change fatal to warnx() for unknown encoding

Hardcore supported encodings list

Mark the INVALID keyword as being deprecated since the concept of
"invalid runes" is useless without the rest of the deprecated rune interface.

Use more verbose diagnostics for wrong DIGIT range

Add checks for DIGIT set consistency to prevent common misinterpretation
automatically.
Remove output file on error.
Staticize functions declared as static.

WARNS=4

WARNS=2, de-__P()

Declarations cleanup; make sure externs are in a common header.
Fix declarations, casts and return values.

Usage style sweep: spell "usage" with a small 'u'.
Also change one case of blatant __progname abuse (several more remain)
This commit does not touch anything in src/{contrib,crypto,gnu}/.

o Move NTOHL() and associated macros into <sys/param.h>. These are
deprecated in favor of the POSIX-defined lowercase variants.
o Change all occurrences of NTOHL() and associated marcros in the
source tree to use the lowercase function variants.
o Add missing license bits to sparc64's <machine/endian.h>.
Approved by: jake
o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
complexities associated with having MD (asm and inline) versions, and
having to prevent exposure of these functions in other headers that
happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

Initialize fp in main()

There is a problem in that one cannot use ctype.h at the same time as parts
of the C++ stdlib. Our ctype.h uses symbols of the form _<X> to denote the
various character classes. Our ctype.h also extends the usual ctype.h
offering by adding the "_T" (special) class. Problem is parts of the STL
also use the symbol "_T" as its parameterized type. These two uses are
incompatible.

Thus change the form of the symbols used in ctype to something that fixes
the current problem and is less likely to cause conflicts in the future.
