- 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.

Add a check for supported bases and set errno (userland) or panic

* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for

shot-term TODO:
- enable multibyte locales. this includes loadable locale modules
(#ifdef DLRUNE).
- populate LC_CTYPE definition files.
- other functions such as iconv()
- make libc functions more friendly with multibyte.
- multilingualize other LC_xx
- torture tests
XXX don't forget to "make depend" when you rebuild libc, multibyte.c is
moved from lib/libc/stdlib to lib/libc/locale.
(also from freebsd). comment out references to reallocf with .\"XXX"
for now. i also fixed some roff misuse as well.
replace calloc(3), free(3) and realloc(3) with links to malloc(3)
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).
