We calculate the size required for the ServerKeyExchange message and then
call BUF_MEM_grow_clean() on the buffer. However we fail to take account of
2 bytes required for the signature algorithm and 2 bytes for the signature
length, i.e. we could overflow by 4 bytes. In reality this won't happen
because the buffer is pre-allocated to a large size that means it should be
big enough anyway.

Now that INCLUDE considers both the source and build trees, no need
for the rel2abs perl fragment hacks any more.
Reviewed-by: NRich Salz <rsalz@openssl.org>

INCLUDE statements in build.info files were source tree centric.  That
meant that to get include directory specs in the build tree, we had to
resort to perl fragments that specified the build tree include paths
as absolute ones.

This change has the INCLUDE statement consider both the source and
build tree for any include directory.  It means that there may be some
extra unnecessary include paths, but it also makes life simpler for
anyone who makes changes in the build.info files.

When the proxy cert code was initially added, some application authors
wanted to get them verified without having to change their code, so a
check of the env var OPENSSL_ALLOW_PROXY_CERTS was added.

Since then, the use of this variable has become irrelevant, as it's
likely that code has been changed since, so it's time it gets removed.
