pkcs11test is passing all tests
Browse files Browse the repository at this point in the history 
Changes
    - wc_HmacInit aware of devId
    - Creation and calling of WP11_Ec_ProvisionedKey_Sign
    - pkcs11test.c changes required due to provisioned key.
    - pkcs11test.c macros guards for SHA224

Stuff that might need to be reverted.
    - NewObject AddObject un-static-ed
    - wp11_Slot_Init disabled code.
    - Call wolfSSL_Init and wolfSSL_CTX_new() in WP11_Library_Init()
    - WP11_Slot_OpenSession disabled code.

This is a work in progress.
