- do not grow memory by doubling its size
- do not leak previously allocated memory if reallocation fails
- replace while-loop with a single check to make sure
that the requested amount of data fits into the buffer

- Prior to this change no SSL minimum version was set by default at
runtime for PolarSSL. Therefore in most cases PolarSSL would probably
have defaulted to a minimum version of SSLv3 which is no longer secure.
- Remove SSLv3 from SSL default in darwinssl, schannel, cyassl, nss,
openssl effectively making the default TLS 1.x. axTLS is not affected
since it supports only TLS, and gnutls is not affected since it already
defaults to TLS 1.x.
- Update CURLOPT_SSLVERSION doc
... for the local variable name in functions holding the return
code. Using the same name universally makes code easier to read and
follow.
Also, unify code for checking for CURLcode errors with:
if(result) or if(!result)
instead of
if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
It turned out some features were not enabled in the build since for
example url.c #ifdefs on features that are defined on a per-backend
basis but vtls.h didn't include the backend headers.
CURLOPT_CERTINFO was one such feature that was accidentally disabled.
Option --pinnedpubkey takes a path to a public key in DER format and
only connect if it matches (currently only implemented with OpenSSL).
Provides CURLOPT_PINNEDPUBLICKEY for curl_easy_setopt().
Extract a public RSA key from a website like so:
openssl s_client -connect google.com:443 2>&1 < /dev/null | \
sed -n '/-----BEGIN/,/-----END/p' | openssl x509 -noout -pubkey \
| openssl rsa -pubin -outform DER > google.com.der
SecCertificateCopyPublicKey() is not available on iPhone. Use
CopyCertSubject() instead to see if the certificate returned by
SecCertificateCreateWithData() is valid.

Forwards the setting as minimum ssl version (if set) to polarssl. If
the server does not support the requested version the SSL Handshake will
fail.

SecCertificateCreateWithData() returns a non-NULL SecCertificateRef even
if the buffer holds an invalid or corrupt certificate. Call
SecCertificateCopyPublicKey() to make sure cacert is a valid
certificate.
If the --cacert option is used with a CA certificate bundle that
contains multiple CA certificates, iterate through it, adding each
certificate as a trusted root CA.
