update README for 4.3 release

the central dns resolver function proxy_gethostbyname() used
to iterate over the gethostent() db (/etc/hosts) on each dns
request.
since this is not threadsafe, we synchronized access to it
previously using mutexes. the parsing of this file is slow,
and blocking all threads to do it even moreso.
since gethostent_r() is only available on a few platforms,
i decided to read the hostent db once and then use a quick
in-memory lookup on further usage.

+ some further refactoring.

-ProxyChains ver 3.1 README
-======================
+ProxyChains ver 4.3 README
+==========================
 
-This is Unix version only.
+  ProxyChains is a UNIX program, that hooks network-related libc functions
+  in dynamically linked programs via a preloaded DLL and redirects the
+  connections through SOCKS4a/5 or HTTP proxies.
 
-How to mess with sources - How to Install : read INSTALL !!!!!!
+*********** ATTENTION ***********
 
-This program forces any tcp connection made by any given tcp client
-to follow through proxy (or proxy chain). It is a kind of proxifier.
-It acts like sockscap / permeo / eborder driver ( intercepts TCP calls )
-It is FREE.
+  this program works only on dynamically linked programs.
+  also both proxychains and the program to call must use
+  the same dynamic linker (i.e. same libc).
+  why ? because in order to hook to libc functions like
+  connect(), dynamic loader facilities are used, namely
+  dl_sym() and LD_PRELOAD.
 
-This version (3.x) introduces support for DNS resolving through proxy 
-it supports SOCKS4, SOCKS5 and HTTP CONNECT proxy servers.
-Auth-types: socks - "user/pass" , http - "basic".
+*********************************
+
+*** Installation ***
+
+  # needs a working C compiler, preferably gcc
+  ./configure
+  make
+  [optional] sudo make install
+
+  if you dont install, you can use proxychains from the build directory
+  like this: ./proxychains4 -f src/proxychains.conf telnet google.com 80
+
+Changelog:
+----------
+
+Version 4.3:
+- fixes programs that do dns-lookups in child processes (fork()ed),
+  like irssi. to achieve this, support for compilation without pthreads
+  was sacrified.
+- fixes thread safety for gethostent() calls.
+- improved DNS handling speed, since hostent db is cached.
+
+Version 4.2:
+- fixes compilation issues with ubuntu 12.04 toolchain
+- fixes segfault in rare codepath
+
+Version 4.1 
+- support for mac os x (all archs)
+- all internal functions are threadsafe when compiled with -DTHREAD_SAFE 
+  (default).
+
+Version 4.0
+- replaced dnsresolver script (which required a dynamically linked "dig" 
+  binary to be present) with remote DNS lookup.
+  this speeds up any operation involving DNS, as the old script had to use TCP.
+  additionally it allows to use .onion urls when used with TOR.
+- removed broken autoconf build system with a simple Makefile.
+  there's a ./configure script though for convenience.
+  it also adds support for a config file passed via command line switches/
+  environment variables.
+
+Version 3.0
+- support for DNS resolving through proxy 
+  supports SOCKS4, SOCKS5 and HTTP CONNECT proxy servers.
+  Auth-types: socks - "user/pass" , http - "basic".

 Configuration:
+--------------
+
 proxychains looks for config file in following order:
-1)	./proxychains.conf
-2)	$(HOME)/.proxychains/proxychains.conf
-3)	/etc/proxychains.conf  **
+1)	file listed in environment variable ${PROXYCHAINS_CONF_FILE} or
+	provided as a -f argument to proxychains script or binary.
+2)	./proxychains.conf
+3)	$(HOME)/.proxychains/proxychains.conf
+4)	/etc/proxychains.conf  **
 
 **see more in /etc/proxychains.conf
 
 Usage Example:
 
-	bash$ proxychains telnet targethost.com
+	$ proxychains telnet targethost.com
 
 in this example it will run telnet through proxy(or chained proxies)
 specified by proxychains.conf
 
 Usage Example:
 
-	bash$ proxyresolv targethost.com
+      	$ proxychains -f /etc/proxychains-other.conf targethost2.com
+
+in this example it will use different configuration file then proxychains.conf 
+to connect to targethost2.com host.
+
+Usage Example:
+
+	$ proxyresolv targethost.com
 
 in this example it will resolve targethost.com through proxy(or chained proxies)
 specified by proxychains.conf
 
-NOTE: 
-to run suid/sgid programs(like ssh) through proxychains you have to be root

+Glibc2 also has reentrant versions gethostent_r(), gethostbyaddr_r(),
+gethostbyname_r() and gethostbyname2_r(). 
+
+The caller supplies a hostent structure ret which will be filled in on success, 
+and a temporary work buffer buf of size buflen. 
+After the call, result will point to the result on success. 
+In case of an error or if no entry is found result will be NULL. 
+The functions return 0 on success and a nonzero error number on failure. 
+In addition to the errors returned by the nonreentrant versions of these functions, 
+if buf is too small, the functions will return ERANGE, and the call should be retried 
+with a larger buffer. 
+The global variable h_errno is not modified, but the address of a variable in which 
+to store error numbers is passed in h_errnop.
