Just for those, who want to build their own apache shell code for
testing purposes, this snip might be of some use. It uses the still
open tcp connections to the server to spawn the shells, so that no
backconnect is needed. Of course, it does not give remote root but
only httpd user privs. And you should send "exec 1>&0" as first
command if you want to see remote shell stdout.

Are there any ideas how to make the code more robust (currently
raciness due to frequent syscalls is problematid), smaller or add
features (I thought using the libc GOT, but this made code larger and
I do not know if that would make code much more portable)?

PS: There is no use to compile or run it, it is just embedded into .c
file for compilation (too lazy to look up gcc args for .S assem)
before insertion into vectors.
