debian/Makefile.am: remove noinst_SCRIPT completely

noinst_SCRIPT makes the postinst maintainer script being regenerated when
re-building the disted tarball, but we do not dist the .in for the Debian
directory.
debian/Makefile.am: add compat file to the disted tarball
configure.in: remove gobject and gmodule dependency

These are not really required by libzorpll itself.
gitignore: add INSTALL and m4 directory
configure.in: support silent mode in Makefiles
src/thread: remove thread pool related unused code

The thread pool code has been removed long ago, so this patch removes
the obsolete command line options, too.
Call PRI callback on HUP

The code path handling the HUP did not call the pri callback. If only
PRI was being watched on a socket on which an ERR/HUP arrives, the
socket will be removed from the poll and always marked as processable
instead. As the pri callback is not called, the socket will not be
processed, causing the polling code to loop indefinitely.
Fix compile error
src/packetbuf: add new constructor initializing the buffer from a GString

This comes handy for the Telnet proxy, for example.
src/packetbuf: add z_pktbuf_put_string() function to append a string to the buffer

This is useful when appending constant string literals to the buffer.
