/*-
* This function determines how parameters are "inherited" from one structure
* to another. There are several different ways this can happen.
*
* 1. If a child structure needs to have its values initialized from a parent
* they are simply copied across. For example SSL_CTX copied to SSL.
* 2. If the structure should take on values only if they are currently unset.
* For example the values in an SSL structure will take appropriate value
* for SSL servers or clients but only if the application has not set new
* ones.
*
* The "inh_flags" field determines how this function behaves.
*
* Normally any values which are set in the default are not copied from the
* destination and verify flags are ORed together.
*
* If X509_VP_FLAG_DEFAULT is set then anything set in the source is copied
* to the destination. Effectively the values in "to" become default values
* which will be used only if nothing new is set in "from".
*
* If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether
* they are set or not. Flags is still Ored though.
*
* If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead
* of ORed.
*
* If X509_VP_FLAG_LOCKED is set then no values are copied.
*
* If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed
* after the next call.
