pkcs15: mandatory 'publicKeyCoefficients' in encode/decode public key procedures

http://www.opensc-project.org/pipermail/opensc-devel/2012-November/018586.html
tool: in 'do_apdu' increase size of send/receive buffers
MyEID ECDSA support
compile on Windows, minor codding style issues
release 0.13.0
pkcs15-tool: initialize 'opt_auth_id' consistently.

All the other option values are initialized to NULL, so do the same to
opt_auth_id.

(Although, as they're all static globals, they should be set to 0 at
runtime anyway, I think...)

cardOS: Use information from AlgorithmInfo

In set_security_env, the algorithmInfo structure (from the TokenInfo file of
PKCS#15) is parsed to see, what algorithm IDs are supported for signature
operations.

Using the information from AlgorithmInfo set in set_security_env when
computing signatures.

Fixed incorrect order of code blocks. If neither a reference to rsa_sig nor to
rsa_pure_sig is found in AlogirthmInfo, boths methods are enabled before (and
not after) trying pure_sig
cardOS: compile on Windows

few coding style remarks
pkcs15: regression in e35febe: compute cert length
