In one failure case, it used to return -1. That failure case
(CTLOG_new() returning NULL) was not usefully distinct from all of the
other failure cases.

This adds the functions X509_set_proxy_pathlen(), which sets the
internal pc path length cache for a given X509 structure, along with
X509_get_proxy_pathlen(), which retrieves it.

Along with the previously added X509_set_proxy_flag(), this provides
the tools needed to manipulate all the information cached on proxy
certificates, allowing external code to do what's necessary to have
them verified correctly by the libcrypto code.

Since there are a number of function pointers in X509_STORE that might
lead to user code, it makes sense for them to be able to lock the
store while they do their work.

We only add setters for X509_STORE function pointers except for the
verify callback function.  The thought is that the function pointers
in X509_STORE_CTX are a cache for the X509_STORE functions.
Therefore, it's preferable if the user makes the changes in X509_STORE
before X509_STORE_CTX_init is called, and otherwise use the verify
callback to override any results from OpenSSL's internal
calculations.
