Subject: OCSP library tidy. Use extension to encode OCSP extensions instead of doing
X-Git-Tag: OpenSSL_0_9_8k^2~1074
X-Git-Url: https://git.openssl.org/?p=openssl.git;a=commitdiff_plain;h=fb596f3bb78bcbeb6831a6454c481563708ef2b3

OCSP library tidy. Use extension to encode OCSP extensions instead of doing
it manually. Make OCSP_CERTID_dup() a real function instead of a macro.
