Octal escape sequences are expanded to bytes, not characters, and multiple
are required for a multibyte character.
The valid escape sequences in %b strings are slightly different from the
escape sequences in the format string.
but \0ddd in a %b argument, with a length restriction of 3 octal digits
in either case. This seems silly, but it needs to be right so it's possible
to write an octal escape followed by an ordinary digit. Solaris printf(1)
and GNU printf(1) also behave this way.
Example: "printf '\0752'" now produces "=2" instead of garbage.
When L is omitted, double precision is used, so printf(1) gives
reproducable results. When L is specified, long double precision is
used, which may improve precision, depending on the machine.
possible to print the thousands separator in the locale setups that
have one, by something like this:
$ env -i LC_NUMERIC=en_US.ISO8859-1 ./printf "%'0.2f\n" 12345
12,345.00

This bug has been around for 22 months... either nobody uses printf
with floating-point values, or people are forgetting to check their
return codes.

Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

Exit with nonzero status if a conversion failed.
Play nice if used as a shell builtin (currently disabled).

processing them.
- \c escape to immediately stop output (similar to echo's \c)
- \0NNN should be allowed for octal character escapes (instead of just \NNN)
- %b conversion, which is like %s but interprets \n \t etc. inside the
string is missing.
And I may not be any poet, but in lieu of an in-tree regression test:
ref5% ./printf '%s%b%b%c%s%d\n' 'PR' '\0072' '\t' '3' '56' 0x10

MFC after: 1 week
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.
used so often that it's worth keeping it as a builtin.
Now that all the printf invocations from within the system startup
scripts, we can safely remove it.

No MFC is planned so far because it may break compatibility and
violate POLA.
