diet libc

32-bit uid/gid support, rand48, thread-safe versions of many functions, adjtime, and many bugfixes.

x86 math routines, a stdio rewrite, no more need for kernel headers, an iconv implementation, openpty, and much more.

This release includes a lot of additions and fixes. The most important ones are
IPv6 DNS routines, a regular expression engine, Sun RPC, realpath, mntent,
scandir, and alphasort, integration of libpthread.a in the build tree,
getserv*, and optional usage of "domain" and "search" from /etc/resolv.conf.
The diet libc can now link openssl, openssh, links, the zsh, busybox, and
several popular Web servers.

Moved object and library files into a separate
directory (bin-$ARCH). Added diet program and a
man page to assist in compiling and linking
against the diet libc. Added fnmatch. Fixed a few
bugs.

This is a major upgrade with numerous new features and fixes. A few highlights include a gethostby{name,addr} with DNS support, crypt, qsort, bsearch, linker warnings, ungetc, an experimental pthreads implementation, kernel 2.0 and 2.2 backwards-compatibility for large file support, support for /etc/localtime (including daylight saving time), pseudo-locale support for ctype based on weak ELF symbols, and much more.
