| Use the same CPU recogition method for FreeBSD 3 as for the other FreeBSD
| versions. (The FreeBSD and FreeBSD-elf Configure entries were identical.)

Because Ulf overlooked the ELF vs. a.out difference, i.e. the two entries were
_NOT_ identical! This way OpenSSL 0.9.4 at least compiles again under FreeBSD
2 and 3. For 0.9.5-dev I'll try to fix the stuff in a more general way to also
allow FreeBSD 4 and other variants.

because it could confuse people (which then send us bug reports)...

even more and I consider this more a useful feature request than a release
showstopper.

LFs into CRLFs when forwarding data from stdin to the TLS connection.
This is necessary for properly talking HTTP.
Because of the code freeze this change is by default disabled for now;
without -DAPPS_CRLF, the code is exactly as before.

with some 0.9.4 changes.

"openssl gendsa -help" now prints the usage summary, not error
messages that now file -help was found.

while implementing and using it.

command shell which means that redirecttion needs backslashes in the paths.

(because now SSL_new makes a copy).

the remainder left in %edx. Here is the resulting performance improvement
matrix (improvement as a result of this *and* previous tune-up committed
two days ago). The results were obtained by profiling the "div" part of
the crypto/bn/bnspeed.c.

CPU	BN_div	bn_div_words	overall	comment
------------------------------------------------------------------------
PII	+16%	accumulated by	+2-3%	PII multiplies damn fast! Taking
		inlining		multiplication out of the loop
					didn't make too much difference.
					Eliminating of the multiplication
					involved in remainder calculation
					is the major factor.

Pentium	+45%	accumulated by	+7-9%	mull isn't that fast and replacing
		inlining		multiplications with additions in
					the loop has more visible effect:-)

MIPS	+75%	+12%		+20-25%	In addition to the taking mults
R10000					out of the loop (giving 12% in the
					asm/mips3.s) three mults were
					eliminated in BN_div.

Alpha	+30%	+50%		+10-15%	Same as above. But remember that
EV4					bn_div_words is a C implementation.
					It takes 4 Alpha mults in C to do
					the same thing as 1 MIPS mult in
					assembler does. So the effect (50%)
					is more impressive. But not the
					overall one... Well, if Alpha
					bn_mul_add would be implemented
					in assembler overall improvement
					would be closer to MIPS...

loop body and replace 'em with addition/subtraction.
