447b543eaf Stopped doing assignments inside expressions.
Who wrote this gem, I wonder?

n -= (e = (e = gunzip_wsize - ((d &= gunzip_wsize - 1) > w ? d : w)) > n ? n : e);

3376298b59 Stop tracking buffer size - it is a constant.
Stop ignoring write errors.
Fix bugs in this line:
rc->buffer_size = read(rc->fd, RC_BUFFER, rc->buffer_size);
(a) should use safe_read()
(b) just ONE short read (e.g. 4 bytes) will make ALL future reads short!

d6772501db tar: fix and sanitize handling of long filenames/linknames
(GNU extensions 'K' and 'L').
We correctly handle them when untarring now, but unfortunately
we still don't use them when tarring! That stupid 100 char limit
is still there!
The biggest problem is that we don't support 'pax' tar format.
Linux kernel tarballs are in this format... shame

d921b2ecc0 Remove bb_ prefixes from xfuncs.c (and a few other places), consolidate
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes...  General cleanup pass.  What I've
been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

b13fee4cbb Since rangecoder is just a bunch of C functions, move it into the one user
(decompress_unlzma.c).  Also a slight #include cleanup, and I've been meaning
to put #include <unistd.h> into libbb.h since it's so darn common...
