FRIGN b6b977f63d Audit tar(1), add DIRFIRST-flag to recurse()
I've been wanting to do this for a while now, as tar(1) used to
be one of messiest and cruftiest tools.
First off, before walking through the audit, I'll talk about
what the DIRFIRST-flag for recurse() does.
It basically calls fn() on the first-level-dir before calling
it's subentries. It's necessary here, because else the order
of the tar-files would've been wrong (it would try to create
dir/file before creating dir/).

Now, to the audit:
1)  Update manpage, fix mistake that compression is also available
    for compressing. It's only available for extracting.
2)  Define the major, minor and makedev macros from glibc by ourselves.
    No need to rely on them, as they are common sense.

decomp()
3)  Simple refactorization.

putoctal()
4)  Add a truncation check for snprintf().

archive()
5)  BUGFIX: Add checks to any checkable function, don't blindly call
    them, this is harmful and there are 100 ways to exploit that.
6)  Use estrlcpy() instead of snprintf() wherever possible, fix
    alignment.
7)  BUGFIX: Terminate the result-buffer of readlink(), check if
    it even succeeded.
8)  Fix sizeof()-formatting.

unarchive()
9)  BUGFIX: Add checks to any checkable function, don't blindly call
    them, this is harmful and there are 100 ways to exploit that.
10) BUGFIX: strtoul can happily return negative numbers. Add checks
    for that and also if the full string has been processed.
11) Remove calls to perror(). We have eprintf, use it.
12) BUGFIX: "minor = strtoul(h->mode, 0, 8);". We need h->minor of
    course.
13) Fix typo "usupported", remove fprintf-call.

print()
14) Check fread().

xt()
15) Get rid of snprintf-magic. Use estrlcat().
16) BUGFIX: check for ferror() on the tarfile.

usage()
17) Update it. The old usage() was like 1000 years old.

main()
18) Add DIRFIRST-flag to the recursor.
19) Don't print usage() when a mode is re-set. We allow this in
    general.
20) Add function checks and fix error messages.
21) Add tarfilename-global for proper error-messages.

sbase - suckless unix tools
===========================

sbase  is a  collection of  unix  tools that  are inherently  portable
across UNIX and UNIX-like systems.

The following tools are implemented ('*' == finished, '#' == UTF-8 support,
'=' == implicit UTF-8 support, '|' == audited, () == petty flag):

The  complement of  sbase  is  ubase[1] which  is  Linux-specific  and
provides all  the non-portable tools.   Together they are  intended to
form a base system similar to busybox but much smaller and suckless.

Building
--------

To  build sbase,  simply  type  make.  You  may  have  to fiddle  with
config.mk depending on your system.

You  can  also  build  sbase-box,  which  generates  a  single  binary
containing  all  the  required  tools.    You  can  then  symlink  the
individual tools to sbase-box or run: make sbase-box-install

Ideally you will  want to statically link sbase.  If  you are on Linux
we recommend using musl-libc[2].

Portability
-----------

sbase has been  compiled on a variety of  different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.

Various combinations of operating  systems and architectures have also
been built.

You can build sbase with gcc, clang, tcc, nwcc and pcc.
