Remove ambiguity in rand_pool_add[_end] return value

When these two functions returned zero, it could mean:

1. that an error occured.  In their case, the error is an overflow of
   the pool, i.e. the correct response from the caller would be to
   stop trying to fill the pool.
2. that there isn't enought entropy acquired yet, i.e. the correct
   response from the caller would be to try and add more entropy to
   the pool.

Because of this ambiguity, the returned zero turns out to be useless.
This change makes the returned value more consistent.  1 means the
addition of new entropy was successful, 0 means it wasn't.  To know if
the pool has been filled enough, the caller will have to call some
other function, such as rand_pool_entropy_available().

Don't use CPP in Configurations/unix-Makefile.tmpl

We started using $(CPP) instead of $(CC) -E, with the assumption that
CPP would be predefined.  This is, however, not always true, and
rather depends on the 'make' implementation.  Furthermore, on
platforms where CPP=cpp or something else other than '$(CC) -E',
there's a risk that it won't understand machine specific flags that we
pass to it.  So it turns out that trying to use $(CPP) was a mistake,
and we therefore revert that use back to using $(CC) -E directly.

Fix a bug in ecp_nistp224.c.

felem_neg does not produce an output within the tight bounds suitable
for felem_contract. This affects build configurations which set
enable-ec_nistp_64_gcc_128.

point_double and point_add, in the non-z*_is_zero cases, tolerate and
fix up the wider bounds, so this only affects point_add calls where the
other point is infinity. Thus it only affects the final addition in
arbitrary-point multiplication, giving the wrong y-coordinate. This is a
no-op for ECDH and ECDSA, which only use the x-coordinate of
arbitrary-point operations.

Note: ecp_nistp521.c has the same issue in that the documented
preconditions are violated by the test case. I have not addressed this
in this PR. ecp_nistp521.c does not immediately produce the wrong

be conservative, or have the bounds analysis and comments reworked for

Fix a text canonicalisation bug in CMS

Where a CMS detached signature is used with text content the text goes
through a canonicalisation process first prior to signing or verifying a
signature. This process strips trailing space at the end of lines, converts
line terminators to CRLF and removes additional trailing line terminators
at the end of a file. A bug in the canonicalisation process meant that
some characters, such as form-feed, were incorrectly treated as whitespace
and removed. This is contrary to the specification (RFC5485). This fix
could mean that detached text data signed with an earlier version of
OpenSSL 1.1.0 may fail to verify using the fixed version, or text data
signed with a fixed OpenSSL may fail to verify with an earlier version of
OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data
and use the "-binary" flag (for the "cms" command line application) or set
the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).

Allow NULL for some _free routines.

Based on the description in https://github.com/openssl/openssl/pull/5757,
this re-implements the "allow NULL to be passed" behavior of a number of
xxx_free routines.  I also fixed up some egregious formatting errors
that were nearby.
