• remove THREAD_SAFE ifdefs. from now on, pthreads are required.

  additionally we have some explicit init and deinit routines for
  core.c now, so that we dont need to share variables with
  libproxychains.c.

• use mutexes also to protect the pipe communication

  wasn't threadsafe before.

• preliminary first fork-safe version

  instead of allocating memory in the child, we now use the allocator
  thread to do all the necessary allocations himself.
  additionally we provide a clean API to query the ip <-> dns mapping.
  these functions connect via a pipe to the allocator thread, and
  exchange messages.
  
  further cleanup is needed, but it seems to work so far.
  thread-safety is not yet guaranteed.
  
  closes #1

• failed attempt to use shared memory for the ip <-> dns mapping

  this is in order to get irssi, which forks for DNS lookups,
  and similar programs, to work as intended.
  
  in a previous attempt i learned that shared memory created in a
  child process is not visible to the parent;
  in this attempt i spin off a thread from the parent which listens
  on a pipe and manages the shared memory allocation from the parent
  address-space. however this doesnt work as expected:
  memory allocated in the parent after the child forked is not visi-
  ble to the child as well.
  
  so what happens is: irssi starts a child process, the thread allocs
  memory and hands it to the child, the child attempts to write and
  segfaults. however irssi doesnt crash. since now the memory is
  already allocated, doing the dns lookup again will succeed.
  
  i.e. the dns lookup works now in irssi by luck.
  all but the first dns lookups will suceed.
  
  however this is not good enough for me to be satisfied, i commit
  this only for documentation purposes.

• main.c: fixed forgotten initialization for second loop using i

  this caused the combination of -q -f somefile to not find the dll
  in the current dir, because it started iterating the directory
  list with 2 instead of 0.

• add RcB tags to core.h

  this is handy as it allows me to do quick testprograms using my RcB program,
  without specifying dozens of things on the command line.

• gethostbyaddr hook: also set aliases.

  i inspected behaviour of libc's and they all seem to set a valid
  h_aliases pointer, of which the first one should be NULL, if no
  aliases exist.

• fix issues with pthread and dlsym symbols on ubuntu 12.04

  for some reason, the linker needs --no-as-needed for both
  libdl and libpthread.
  
  closes #4
  
  thanks to @tomsawyer for discovering this.
  
  the proposed -pthread change was not needed though,
  and this is a good thing since it seems not portable.

• fix bug which lead to segfault in ubuntu 12.04 telnet

  it called gethostbyname and expected that the h->h_name was set.
  
  this code path here which gets only active if the passed name
  equals the gethostname() result failed to set a couple of values.
  
  additionally fixed usage of strncpy, which causes the entire
  memory buffer to be written, even when the string is much shorter.
  
  a similar bugfix was independently discovered by semion laptev, but my
  version is threadsafe - his version introduces a new static buffer,
  even though we have plenty of thread-safe space reserved exactly
  for this usage case, thus causing a regression.
