2445ce72d2 Be slightly more careful about freeing memory allocated for environment 
variables: only free memory if the current value points to the same
memory area as the allocated block. This will prevent crashes if an
application changes the order of the environment array.

Unfortunately this is still not enough to stop zsh 4.2.* from crashing.
zsh 4.3.* works fine before and after this change.

5cdca2e600 Remember memory used by allocated environment variables instead of 
using a bitmap. This deals with the case where a variable is first
set via setenv(3) or putenv(3), then overwritten by changing
"environ" directory and afterwards overwritten with setenv(3) again.

This stops "zsh" from crashing under NetBSD-current.

e957123b85 PR/43899: Nicolas Joly: setenv(3)/unsetenv(3) memory leak. 
Partial fix: Don't allocate a new string if the length is equal to the
old length, because presumably the old string was also nul terminated
so it has the extra byte needed.
The real fix is to keep an adjunct array of bits, one for each environment
variable and keep track if the entry was allocated or not so that we can
free it in unsetenv.

4c92852a80 remove almost all the ability to build netbsd with an a.out target. 
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format.  ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k.  this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
  down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

64a7d4fa9a 1. hide _CTYPE_PRIVATE section in ctype.h, move them to private header ctype_local.h. 
2. do not use _CTYPE_NUM_CHARS macro to read data from LC_CTYPE(old BSDCTYPE style) database.
   because 1<<CHAR_BIT is MD, so i added MI macro _CTYPE_CACHE_SIZE(1<<8).
3. remove _NB_CACHED_RUNE macro, use _CTYPE_CACHE_SIZE instead.

longer mandated that the directory streams are implemented by using file
descriptors.)

4519228649 Improvements to wording and markup. 
In addition, list more bugs and caveats. Namely, the NetBSD implementation
(like the FreeBSD one where this was ported to) requires that the comparison
keys are allocated dynamically, and that hdestroy() will try to free(3) each
key. This obviously severely limits the portability, given that other
implementations (for example, the Linux one) make no such assumptions. Both
approaches are legitimate, and thus the real bug is in the ambiguity of the
standard.
