Import of SSLeay-0.9.0b with RSA and IDEA stubbed + OpenBSD build

functionality for shared libs.

Note that routines such as sslv2_init and friends that use RSA will
not work due to lack of RSA in this library.

Needs documentation and help from ports for easy upgrade to full
functionality where legally possible.

+The perl scripts in this directory are my 'hack' to generate
+multiple different assembler formats via the one origional script.
+
+The way to use this library is to start with adding the path to this directory
+and then include it.
+
+push(@INC,"perlasm","../../perlasm");
+require "x86asm.pl";
+
+The first thing we do is setup the file and type of assember
+
+&asm_init($ARGV[0],$0);
+
+The first argument is the 'type'.  Currently
+'cpp', 'sol', 'a.out', 'elf' or 'win32'.
+Argument 2 is the file name.
+
+The reciprocal function is
+&asm_finish() which should be called at the end.
+
+There are 2 main 'packages'. x86ms.pl, which is the microsoft assembler,
+and x86unix.pl which is the unix (gas) version.
+
+Functions of interest are:
+&external_label("des_SPtrans");	declare and external variable
+&LB(reg);			Low byte for a register
+&HB(reg);			High byte for a register
+&BP(off,base,index,scale)	Byte pointer addressing
+&DWP(off,base,index,scale)	Word pointer addressing
+&stack_push(num)		Basically a 'sub esp, num*4' with extra
+&stack_pop(num)			inverse of stack_push
+&function_begin(name,extra)	Start a function with pushing of
+				edi, esi, ebx and ebp.  extra is extra win32
+				external info that may be required.
+&function_begin_B(name,extra)	Same as norma function_begin but no pushing.
+&function_end(name)		Call at end of function.
+&function_end_A(name)		Standard pop and ret, for use inside functions
+&function_end_B(name)		Call at end but with poping or 'ret'.
+&swtmp(num)			Address on stack temp word.
+&wparam(num)			Parameter number num, that was push
+				in C convention.  This all works over pushes
+				and pops.
+&comment("hello there")		Put in a comment.
+&label("loop")			Refer to a label, normally a jmp target.
+&set_label("loop")		Set a label at this point.
+&data_word(word)		Put in a word of data.
+
+So how does this all hold together?  Given
+
+int calc(int len, int *data)
+	{
+	int i,j=0;
+
+	for (i=0; i<len; i++)
+		{
+		j+=other(data[i]);
+		}
+	}
+
+So a very simple version of this function could be coded as
+
+	push(@INC,"perlasm","../../perlasm");
+	require "x86asm.pl";
+	
+	&asm_init($ARGV[0],"cacl.pl");
+
+	&external_label("other");
+
+	$tmp1=	"eax";
+	$j=	"edi";
+	$data=	"esi";
+	$i=	"ebp";
+
+	&comment("a simple function");
+	&function_begin("calc");
+	&mov(	$data,		&wparam(1)); # data
+	&xor(	$j,		$j);
+	&xor(	$i,		$i);
+
+	&set_label("loop");
+	&cmp(	$i,		&wparam(0));
+	&jge(	&label("end"));
+
+	&mov(	$tmp1,		&DWP(0,$data,$i,4));
+	&push(	$tmp1);
+	&call(	"other");
+	&add(	$j,		"eax");
+	&pop(	$tmp1);
+	&inc(	$i);
+	&jmp(	&label("loop"));
+
+	&set_label("end");
+	&mov(	"eax",		$j);
+
+	&function_end("calc");
+
+	&asm_finish();
+
+The above example is very very unoptimised but gives an idea of how
+things work.
+
+There is also a cbc mode function generator in cbc.pl
+
+&cbc(	$name,
+	$encrypt_function_name,
+	$decrypt_function_name,
+	$true_if_byte_swap_needed,
+	$parameter_number_for_iv,
+	$parameter_number_for_encrypt_flag,
+	$first_parameter_to_pass,
+	$second_parameter_to_pass,
+	$third_parameter_to_pass);
+
+So for example, given
+void BF_encrypt(BF_LONG *data,BF_KEY *key);
+void BF_decrypt(BF_LONG *data,BF_KEY *key);
+void BF_cbc_encrypt(unsigned char *in, unsigned char *out, long length,
+        BF_KEY *ks, unsigned char *iv, int enc);
+
+&cbc("BF_cbc_encrypt","BF_encrypt","BF_encrypt",1,4,5,3,-1,-1);
+
+&cbc("des_ncbc_encrypt","des_encrypt","des_encrypt",0,4,5,3,5,-1);
+&cbc("des_ede3_cbc_encrypt","des_encrypt3","des_decrypt3",0,6,7,3,4,5);
