Ruslan Ermilov 40e7fc1a20 More potential buffer overflow fixes.
o Fixed `nfrontp' calculations in output_data().  If `remaining' is
  initially zero, it was possible for `nfrontp' to be decremented.

Noticed by:	dillon

o Replaced leaking writenet() with output_datalen():

:  * writenet
:  *
:  * Just a handy little function to write a bit of raw data to the net.
:  * It will force a transmit of the buffer if necessary
:  *
:  * arguments
:  *    ptr - A pointer to a character string to write
:  *    len - How many bytes to write
:  */
: 	void
: writenet(ptr, len)
: 	register unsigned char *ptr;
: 	register int len;
: {
: 	/* flush buffer if no room for new data) */
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 	if ((&netobuf[BUFSIZ] - nfrontp) < len) {
: 		/* if this fails, don't worry, buffer is a little big */
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 		netflush();
: 	}
:
: 	memmove(nfrontp, ptr, len);
: 	nfrontp += len;
:
: }  /* end of writenet */

What an irony!  :-)

o Optimized output_datalen() a bit.

$FreeBSD$

This directory is for the EXACT same use as src/contrib, except it
holds crypto sources.  In other words, this holds raw sources obtained
from various third party vendors, with FreeBSD patches applied.  No
compilation is done from this directory, it is all done from the
src/secure directory.  The separation between src/contrib and src/crypto
is the result of an old USA law, which made these sources export
controlled, so they had to be kept separate.
