• add new --fat-binary-m2 option

  this enables arm64e in the proxychains4 binary additionally to the
  injected library, which already did so with the -m1 option.

• fix potential double-close of file descriptors

  in case of an error condition, both start_chain() and chain_step()
  were closing the fd to be acted upon, without setting it to -1,
  and the function calling them would close them again.
  
  this could affect multi-threaded applications that opened new fds
  between the first and the second close, invalidating those fds
  in the targeted app.
  
  patch loosely based on report and PR by @jhfrontz.

• fix resolving of proxy names with proxy_dns_daemon

  closes #497
  
  in order to make this work, also the change in 2d265582a2
  was required; otherwise the sendto() call from rdns lookup would
  cause the init code to be called from within the init code and
  ultimately hanging on pthread_once().

• disable lazy init if compiler supports GCC constructor attribute

  before we started to use the gcc constructor attribute to load our
  initialization code, each function hook used to check whether the
  initialization was already done, and if not, do it at that point.
  
  this workaround is quite ugly, and creates a circular reference
  if the startup code calls any of the hooked functions.
  
  now we only do the lazy init if the compiler used is not GCC
  compatible.

• fat-binary-m1: use arm64e for dylib, but not for executable

  according to research done by @malash, the proxychains4 binary
  itself isn't allowed to use system-internal arm64e mode; but
  it's possible to add it as a 3rd architecture to the shared
  library (.dylib), and then even inject it into system binaries
  like /usr/bin/curl, which didn't work since the introduction
  of SIP.
  
  therefore, we now create the dylib with all 3 archs, but the
  launcher only with arm64 and x86_64.

• proxy_getaddrinfo(): Fill in ai_socktype if requested

  If the application specifies a protocol but not a socket type,
  normally getaddrinfo will select a corresponding protocol.
  
  Mimic this behavior in our implementation of the function as well.
  We only care about the case we're actually able to proxify
  (SOCK_STREAM / IPPROTO_TCP).
  
  Fixes proxifying pssh.

• introduce HOOKFUNC macro to mark all libc hook functions

  this is currently a NO-OP, but it's already useful in that it
  clearly marks our hook functions that override libc.
  this in preparation of adding support for MacOS 12.0.1 "Monterey",
  which apparently requires a new dynlinker hooking method.

• remove 10 year old workaround for wrong glibc getnameinfo signature

  in ce655fdac8 the getnameinfo function
  was factored into a separate TU to prevent its POSIX signature from
  colliding with GLIBC's wrong prototype. since this has been fixed
  in GLIBC 10 years ago, it should be safe by now.
  undoing the workaround has the advantage that all hooked functions
  are now available in the same place, which is a prerequisite for
  a change i'm about to commit.
  
  if it turns out there's still systems in use that use the old GLIBC
  version with the wrong prototype, we can add a configure check
  dealing with it.

• proxychains.conf: fix localnet documentation

  localnet with hostnames/DNS is not compatible with remote dns - if remote dns
  is activated we get an ip from the remote dns resolver in the connect() call,
  so we don't know whether the destination would match any localnet - except
  from the ANY localnet 0.0.0.0 - in which case we would need to do a real DNS
  lookup with the remote DNS ip involving both the rdns resolver to get the
  original hostname back and then call the native DNS resolver function - for
  which there is only getaddrinfo() when we don't want to support the 5
  different gethostbyname_r() variants in existence, or using getaddrinfo(),
  which in turn requires memory allocation/free() - in other words a huge mess.
  we also can't easily check in the resolver whether an ANY-destination localnet
  is enabled and the port matches, because the resolver might only resolve the
  hostname at this stage, but not the destination port.
