Implement mark & sweep garbage collection as suggested by Enami Tsugutomo
...
on "current-users" mailing list. Garbage collection is performed if:
1.) We previously allocated memory for the environment array which
is no longer used because the application overwrote "environ".
2.) We find a non-NULL pointer in the allocated environment array after
the end of the environment. This happens if the applications attempts
to clear the environment with something like "environ[0] = NULL;".

Improve and simplify implementation of *env(3) functions:
...
- Use RB tree to keep track of memory allocated via setenv(3) as
suggested by Enami Tsugutomo in private e-mail.
This simplifies the code a lot as we no longer need to keep the size
of "environ" in sync with an array of allocated environment variables.
It also makes it possible to free environment variables in unsetenv(3)
if something has changed the order of the "environ" array.
- Fix a bug in getenv(3) and getenv_r(3) which would return bogus
results e.g. for " getenv("A=B") " if an environment variable "A"
with value "B=C" exists.
- Clean up the internal functions:
- Don't expose the read/write lock for the environment to other parts
of "libc". Provide locking functions instead.
- Use "bool" to report success or failure.
- Use "ssize_t" or "size_t" instead of "int" for indexes.
- Provide internal functions with simpler interfaces e.g. don't
combine return values and reference arguments.
- Don't copy "environ" into an allocated block unless we really need
to grow it.
Code reviewed by Joerg Sonnenberger and Christos Zoulas, tested by
Joerg Sonnenberger and me. These changes also fix problems in
zsh 4.3.* and pam_ssh according to Joerg.

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.

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.

Fix several end cases:
...
o If a long option looks like an ambiguous abbreviation of two or more long
options, but all the possible interpretations would return the same
value, then just return that value without complaining that it's
ambiguous.
o If a long option could be interpreted either as an exact match for one
long option, or as an abbreviation for one or more other long options,
then treat it as the exact match.
These changes align NetBSD's getopt_long(3) with the current behavior of
GNU getopt_long(3), the de facto standard, and FreeBSD's getopt_long(3).

Rewrite erand48() to put the random bits into the mantissa by simple

(for ieee doubles only -- vax can't use it, so the old version
needs to stay around)
This removes the dependency on ldexp() which also didn't participate in
the usual __RENAME game, thus lead to confusion.
In addition, this version is almost 3 times as fast for me.
