c-icap: new package

[Thomas:
 - Remove trailing whitespace everywhere
 - Rewrap the Config.in help text
 - Fix Config.in comment, the proper text for BR2_PREFER_STATIC_LIB is
   "dynamic library", not "libdl library"
 - Use a PID file in the init script
 - Show OK / FAIL when stopping the service
 - Remove the largefile/IPv6 handling in c-icap.mk, since they are now
   mandatory. We therefore pass --enable-large-files and --enable-ipv6
   unconditionally.
 - Remove the reference to a non-existing
   C_ICAP_INSTALL_TARGET_CONFIGS install target hook.
 - Install the init script unconditionally.
 - Remove unneeded example configuration files (*.default) from /etc,
   and fixup the c-icap.conf so that the default values work with
   Buildroot
 - Properly handle the *-config scripts installed by c-icap.
 - Add hash file.]

+	  c-icap is an implementation of an ICAP server. It can be
+	  used with HTTP proxies that support the ICAP protocol to
+	  implement content adaptation and filtering services.  Most
+	  of the commercial HTTP proxies must support the ICAP
+	  protocol.  The open source Squid 3.x proxy server supports
+	  it.
