fd5cb0acea A little libc namespace housekeeping exercise: 
* Make vfprintf_unlocked() an internal function, c.f. __svfscanf_unlocked().
* Add internal names for arc4random(), endnetpath(), fhstatvfs(),
  fstatvfs(), mkstemp(), shquote(), statvfs(), taddr2uaddr(), uaddr2taddr(),
  uuid_create_nil(), uuid_is_nil(), and wcwidth().
* Include namespace.h where supposed to.

b2f782612f Completely rework how tools/compat is done. Purge all uses/references to 
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

db594c6591 After discussion with christos, turn fgetstr() into an internal function. 
Its API in inherently non-threadsafe (and it depends on certain properties
of the underlying stdio implementation), so it shouldn't be a first-class
function for general use, polluting the application namespace.
Also remove the FLOCKFILE() code from it - this is under control of the
calling function now.
(XXX I'm not sure whether the FLOCKFILE() should be kept in fgetln(),
this function cannot be used in multiple threads anyway. It doesn't
hurt much, and it might prevent corruption of internal FILE structures.)

7fd2c31d41 Add support for scanf "hh" format modifiers - we use it in int_fmtio.h 
for SCNd8 and friends - so we should support it properly (and not only
by pure luck on alignment blind little endian archs - it used the
"h" code path, storing a 16bit int via a byte pointer).

This makes sparc64 pass regress/lib/libc/int_fmtio.

171d653219 Overhaul how `build.sh tools' are used: 
*	Rename "config.h" to "nbtool_config.h" and
	HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
	This makes in more obvious in the source when we're using
	tools/compat/config.h versus "standard autoconf" config.h

    *	Consistently move the inclusion of nbtool_config.h to before
    	<sys/cdefs.h> so that the former can provide __RCSID() (et al),
    	and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
	#if HAVE_NBTOOL_CONFIG_H
	#include "nbtool_config.h"
	#endif
to the top of the source files (for the general case).

6d30f1a3db Disable cancellation on the first lock, too, not just on internal 
recursive locks (Duh).

Disable cancellation around the cond_wait() call, since that's also a
cancellation point. Arguably, that would be better handled with
pthread_cleanup_*(), but stubbing those for libc is difficult, and the
current non-exception-based implementation of cleanup handlers is
probably no faster than disabling and reenabling cancellation.
Finally, it only happens in the slow path where the thread is going to
sleep anyway...

ad09d62fcc Move guts of flockfile()/funlockfile() to __flockfile_internal(), which 
takes an additional argument indicating whether this is an internal caller
taking the lock or an external (application) caller. When making an internal
lock, save the current thread cancellation state and disable cancellation
until the matching unlock. This should prevent canccelled threads from exiting
inside of stdio while holding a file lock and potentially leaving other
parts of the FILE structure in an inconsistent state.

a505fc7826 Fix two bugs: 
1. snprintf(foo, 0. "XXX") is guaranteed not to write in foo by the
   standard (ISO/IEC 9899 7.19.6.5) but our implementation handles this
   as if the buffer has a size of (size_t)-1.

2. snprintf(NULL, 0, "XXX") leaks memory since cantwrite() allocates
   memory if _bf._base == NULL, and this buffer is never freed
   (PR 16483).
